Difference Between Angiosperm and Gymnosperm (Structure)

Plants are divided into two major groups of plants. These are known as gymnosperms and angiosperms. The main Differences Between Angiosperm and Gymnosperm are reproductive structure, seed distribution, and how they reproduce.

These two types of plants are so different that it is difficult to understand how they could be related. However, when one examines all of the characteristics, similarities in structure begin to appear. 

The following paragraphs will explain the Difference Between Angiosperm and Gymnosperm, in order to better elucidate how they are related.


Gymnosperms are seed-bearing plants that don’t produce flowers or fruit. These plants, such as conifers and cycads, reproduce through releasing pollen and ovules into the air. This pollen and ovule mix is then fertilized by insects or wind if they happen to be in the area. 

Gymnosperms were the dominant plant life on Earth for the majority of the Mesozoic Era, but scientists have found fossils dating back to the Carboniferous Period.

Gymnosperm means “naked seed” in Greek. This name refers to the lack of an ovary wall in the seed, i.e. the seed is not fully enclosed by carpels or modified leaves. 

The name is quite fitting because most gymnosperm seeds are indeed naked, and several gymnosperms lack leaves altogether. Gymnosperms are one of three subdivisions of spermatophytes or seed plants.

Gymnosperms are vascular plants that produce seeds but lack flowers and are not flowering plants. This group includes conifers, cycads, Ginkgo, gnetophyte, and other less familiar groups. 

Gymnosperms produce cones, similar to those of flowering plants, but are unrelated to them. 

The female cone of a gymnosperm is not only woody like the female cone of a flowering plant, but is also dry at maturity, with the ovules exposed on the scale surface.

Gymnosperms are seed-producing plants that don’t produce flowers. Because of this, they are sometimes referred to as “naked-seeded” plants. 

Gymnosperms are also sometimes called “naked-seed” plants. The term “gymnosperm” comes from the Greek word “gymnos,” which means “naked seed.”


Angiosperms are plants that have seeds in which the embryo grows in a protective covering. They are the dominant plant form today, especially in the world’s ecosystems. 

They appeared on Earth about 140 million years ago, and the first ones were small, scaly, and grew in water. They were only about a millimeter tall, but since then angiosperms have evolved into the trees, shrubs, and flowers we see today.

An angiosperm is a plant that produces seeds in an ovary instead of an egg. This new type of plant evolved from ancestors that reproduced via spores, like ferns and mosses. 

The first angiosperms appeared on Earth about 130 million years ago. They gave rise to all the plants we have today, including trees, shrubs and flowers.

Angiosperms are flowering plants. They represent the third and final stage of the evolution of plants. The first plants were simple, non-flowering, and grew in water or on land. The second stage was the gymnosperms.

Angiosperms are flowering plants. They have pollen and seeds. They are the dominant plants on Earth today, making up most of the world’s forests.

The Angiosperms are flowering plants. They have seeds instead of spores, and they have petals and produce seeds inside a fruit.

Difference Between Angiosperm and Gymnosperm

What's are the Differences Between Angiosperm and Gymnosperm?

In the present context, the origin and diversification of flowering plants is of fundamental importance for understanding the history of terrestrial ecosystems and the evolution of the biosphere. 

The best-documented and most widely accepted hypothesis is that angiosperms evolved from within a group of gymnosperms during the Early Cretaceous (125–80 million years ago) and diversified subsequently. 

Gymnosperms and angiosperms are two types of seed-bearing plants. The former is a seed-bearing plant that does not produce flowers and the latter is a seed-bearing plant that does produce flowers. 

The major difference between the two lies in the reproductive system they adopt for the distribution of their seeds. This paper discusses the differences between the two reproductive systems and their significance in defining a plant as a Gymnosperm or an Angiosperm.

Gymnosperms and angiosperms, both show many features in common, but also a number of differences. Like all seed plants, they produce flowers to produce seeds that have a hard coating. 

The differences between them lie in the way that the seeds are formed and where they are formed.

Both these groups of plants have innumerable numbers of species. A majority of plants that are found on earth belong to these two groups.

Gymnosperms and Angiosperms, they contain different types of plant cells and have different life cycles. Gymnosperms and Angiosperm plants also have different physical structures and tissues. 

Some people use the term ‘gymnosperm’ to refer to the whole group of plants, including both gymnosperms and angiosperms.

Gymnosperms and Angiosperms are both utilize the process of photosynthesis to produce energy and grow. However, they do have some key differences which set them apart from each other.

The main differences between Gymnosperms and Angiosperms are the reproductive structures, the distribution of seeds, and the way in which they reproduce.

FAQs for Difference Between Angiosperm and Gymnosperm

Q1. What is the difference between angiosperm and gymnosperm xylem?

Ans. The difference between angiosperm and gymnosperm xylem is that angiosperm xylem is composed of vessels, tracheid, and fibers, while gymnosperm xylem is composed of tracheid only.

Angiosperm xylem vessels are larger in diameter than gymnosperm xylem vessels. Angiosperm xylem vessels are also found in perennial plants whereas gymnosperm xylem vessels are found in conifers. 

Angiosperm xylem vessels are also surrounded by a lignified secondary cell wall, while gymnosperm xylem vessels lack a secondary cell wall. 

The secondary cell wall in angiosperm xylem vessels provides structural support, while the lack of a secondary cell wall in gymnosperm xylem vessels means that the cells can expand and contract more, 

Q2. Why are angiosperms better than gymnosperms?

Ans. Angiosperms are better than gymnosperms because angiosperms have fruits whereas gymnosperms don’t have fruits. 

Also, angiosperms have flowers whereas gymnosperms have none. Also, angiosperms are better because they are capable of seed production. 

Also, angiosperms are better because they produce seeds in cones, whereas gymnosperms produce seeds in naked clusters.

Q3. Do we eat gymnosperms?

Ans. Yes, we eat gymnosperms in several forms. Some species are harvested as a dietary supplement. Some have been used as a source of fiber. Some are used in the pharmaceutical industry as a source of starch, cellulose, or other sugar compounds.

Q4. Are angiosperms or gymnosperms more common on Earth?

Ans. Of the two, angiosperms have been found to be more common on Earth. Research has shown that on average angiosperms make up 88% of plants on Earth, with gymnosperms on the other hand making up a mere 12% of plants on Earth. 

The plant kingdom is a very diverse one and on first glance it may seem as if there is little difference between angiosperms and gymnosperms. However, looking beyond the surface reveals two very different types of plants.

Q5. Why are conifers classified as gymnosperms and not angiosperms?

Ans. Conifers are gymnosperms. They’re a group of flowering plants that reproduce using seeds instead of pollen. Angiosperms, on the other hand, are flowering plants that produce their seeds inside an ovary. They produce their seeds using pollen, not seeds, and their ovaries are usually enclosed in a fruit.

Q6. Why angiosperms are called flowering plants?

Ans. There is a general impression that angiosperms are called flowering plants because they have flowers. 

But all flowering plants have flowers, so this cannot be the reason why they are called flowering plants. 

The real reason is that angiosperms have flowers with a certain kind of structure that is only found in angiosperms. This structure is called a flower-like structure, and it consists of a flower-like unit called a flower.

Q7. Do angiosperms produce pollen?

Ans. Yes, angiosperms do produce pollen, and they have a very specific function. Angiosperms produce pollen to pollinate other angiosperms. 

Angiosperm pollen is usually white to light yellow and is produced in large amounts of pollen. Pollination is not a very significant factor in angiosperm reproduction because most are autogamous species.

Q8. Is a pineapple a Gymnosperm?

Ans. The pineapple is a type of flowering plant in the lilies or loranthaceae family. The pineapple is actually classified as a gymnosperm because it shares certain characteristics with them. In this case the pineapple is classified as a gymnosperm because of its cone-bearing inflorescence, which is typically a feature of the gymnosperms, and because of the lack of leafy petioles. The petioles are found on the branches, which is a feature of the angiosperms.

Q9. Do gymnosperms bear fruit?

Ans. What fruit did they bear? The answer is no, not at least for any that we know of. The gymnosperm was an important group during the Paleozoic Era, and some fossils have been found that seem to be plants of the gymnosperm (seed) type. But the gymnosperm has been an evolutionary dead end.

Q10. Do only angiosperms produce fruit?

Ans. Does only angiosperm (=flowering plants) produce fruit? Plant reproductive mode can be examined at multiple scales, ranging from the individual (trees, herbaceous perennials and annuals, and grasses) to the community (ecosystems). 

A phylogenetic analysis of flowering plants (angiosperms) revealed that, within angiosperms, there are three major reproductive modes, termed autogamous, facultative, and obligate (i.e., hermaphroditic). The autogamous mode involves pollen and/or pollen tubes that land and develop on a receptive stigmatic surface, and is thus the most common mode of reproduction in flowering plants.

Q11. Do angiosperms have chlorophyll?

Ans. No. The presence of chlorophyll in angiosperms does not imply that the plant has a green or vascular tissue. The photosynthetic pigments in plants are chlorophylls, but these pigments are not necessarily located in tissues that are vascular, or photosynthetic. 

When the term “green plant” is used, it usually means a plant having a green vascular tissue – i.e., having a central vascular cylinder surrounded by phloem parenchyma, typically in association with bundles of xylem fibers.

Q12. Do gymnosperms have chlorophyll?

Ans. Yes, gymnosperms have chlorophyll, and it doesn’t have the same function as in angiosperm photosynthetic mechanism. Chlorophyll in gymnosperms is needed for light-mediated energy transfer. It doesn’t play a role in greening the plant as in angiosperms. 

Q13. How do gymnosperms reproduce?

Ans. Gymnosperms reproduce through the production of pollen. Pollen is carried by wind to the stigmas of the trees on which the pollen lands and is dispersed within the pollens. 

When this happens, the pollen grains fuse together in a flower, releasing the pollen and the pollen tube that contains the pollen, which has now germinated. 

The pollen tube then travels up the axis of the ovule, making a hole in the membrane of the ovule via which it enters the ovule.

Q14. Do gymnosperms pollinate?

Ans. Do gymnosperms pollinate? A recent study suggests that they do not, but further investigation may shed more light on the subject. 

The following study sought to evaluate whether gymnosperms (the plant group to which conifers and angiosperms belong) have reproductive strategies similar to angiosperms. 

This was done by comparing the mating systems of the two groups, and by determining whether or not the pollination strategies of gymnosperms could be explained by the pollination biology of angiosperms.

Q15. Did angiosperms evolved from gymnosperms?

Ans. The story of the angiosperms (flowering plants) evolving from gymnosperms (non-flowering plants) has been controversial for more than a century. The two groups of plants are very different in structure and function today. 

Although there are many differences, these can be accommodated by different evolutionary steps. 

In the first step, gymnosperm and angiosperm ancestors were similar, and that similarity may represent an intermediate stage of their evolutionary history.
