Angiosperms or seed-producing plants that include fruits produce naked seeds, usually found in cones. Examples are roses angiosperms, and so are mangoes, but pines and ginkgoes are gymnosperms. Both are vascular plants with both xylem and phloem, but their reproductive structures and ecological roles differ. This chapter on the Plant Kingdom in Biology talks about the difference between angiosperms and gymnosperms, the two major kinds of seed-producing plants. The contrast in these questions is something that students from the country would have to know if they are preparing themselves for NEET and JEE.

An angiosperm plant is called a flowering plant, whereas a gymnosperm plant is called a non-flowering plant. These plants are classified into vascular-containing plant groups. Gymnosperms are ancient time plants found to date on the earth. Angiosperm plant flowers can be bisexual or unisexual. Bisexual, means both male and female flowers present in the same plant; and unisexual, means any one male or female flower present in the same plant. Angiosperm includes different types of body forms such as herbs, shrubs, vines, and trees.
Angiosperm plants are divided into various families such as the Orchidaceae family, the Asteraceae family, Fabaceae family. The Orchidaceae family plant (called an orchid) is found higher in number and it is generally found over the rocks and pollinated by fly vectors. The Asteraceae family is also called the composite family, it is mostly found in high-temperature regions and subtropical regions of the earth. The fabaceae family is also called the legume family and this family is the third largest angiosperm family which can produce root nodules which is beneficial for bacteria as well as plants to do nitrogen fixation.

The terminology, angiosperm and gymnosperm is used in the field of botany. These both words are Greek words. Gymnosperm is made up of two words that is ‘gymnos’ and ‘Sperma’, ‘gymnos’ means opened or uncovered and ‘sperma’ means seed; the word angiosperm is also made up of two words ‘Angeoin’ and ‘Sperma’, ‘Angeoin’ means vessel or hollow structure within seed and 'Sperma’ means seed.
The difference between angiosperm and gymnosperm with some examples lies primarily in their seed structure, where angiosperms have seeds enclosed in fruits, such as apples and oranges, while gymnosperms have naked seeds found on cones, like pine cones. To write the difference between angiosperm and gymnosperm, one must note that angiosperms produce seeds enclosed within fruits, while gymnosperms have naked seeds that are not protected by any covering. When you write about the difference between angiosperm and gymnosperm, it is essential to mention that angiosperms are characterized by their flowers, which facilitate diverse pollination methods, whereas gymnosperms primarily reproduce using cones.
Aspect | Angiosperms | Gymnosperms |
---|---|---|
Pollination Methods | Utilize various pollination methods, including animal, wind, and water. | Primarily rely on wind for pollination. |
Seed Structure | Seeds are covered by plant structures such as fruit. | Seeds are present on leaves. |
Flower Production | Angiosperms are a group of plants that can produce flowers. | Gymnosperms are a group of plants that have no flowers in their life cycle. |
Reproductive System Location | The reproductive system is found within flowers. | The reproductive system occurs within cones. |
Leaf Structure | Flat leaf structure is shown by angiosperms. | Edge or needle-like structure is shown by gymnosperms. |
Growth Conditions | Angiosperm plants are grown in every season of the year. | Gymnosperm plants are grown in specific seasons and regions on Earth. |
Tissue Type | Triploid tissue is found in angiospermic plants. | Haploid tissue is found in gymnospermic plants. |
Pollination Medium | Media like animals, wind, and water is required for the pollination process. | Medium like wind is required for the pollination process. |
Wood Structure | The wood structure or trunk of angiosperm plants is harder than that of gymnosperm plants. | Soft trunks are found in gymnosperm plants. |
Vessels Presence | Angiosperms do not contain vessels. | Vessels are present within gymnosperms. |
Phloem Composition | Angiosperm phloem lacks companion cells. | Companion cells are found within the gymnosperm phloem. |
Reproductive System Structure | In angiosperms, the reproductive system is present within flowers. | In gymnosperms, the reproductive system is present within cones. |
Fertilization Type | Double fertilization is found within angiosperms. | Double fertilization is not found in gymnosperms. |
Style and Stigma Presence | Style and stigma are present within angiosperms. | Style and stigma are not found in gymnosperms. |
Archegonia Presence | Archegonia is found in angiosperms. | Archegonia is not found in gymnosperms. |
Sperm Motility | Sperm is immotile in angiosperms. | Sperm is motile in gymnosperms. |
Reproductive Structures | Angiosperms produce flowers that can be unisexual or bisexual. | Gymnosperms produce cones that are generally unisexual. |
Habitat Preferences | Angiosperms thrive in a variety of environments from tropical rainforests to deserts. | Gymnosperms are commonly found in temperate forests and mountainous regions. |

Angiosperm means seed is produced by flowering plants and it is enclosed in the ovaries. Gymnosperm means seed is produced by a non-flowering plant and seed is either closed or uncovered.
1.Gymnosperm non covered seed is observed and covered seed found in angiosperm. 2.Archegonium not found in gymnosperm, but it is found within the angiosperm. 3.Gymnosperm plants grow in specific seasons and conditions but angiosperm plants grow in all conditions.
Angiosperm is made up of ‘angeoin’ and ‘sperma’ words, ‘angeoin’ means vessel-like structure and ‘sperma’ means seed. Gymnosperm term is made up of ‘gymnos’ and ‘sperma’ words, ‘gymnos’ means opened or uncovered and ‘sperma’ means seed.
Gymnosperm plant is the oldest plant.
Apple, hemp, orchids, lilies, walnut are examples of angiosperm plants; And pine, spruce, ginkgo, cycas, pins, araucaria, thuja, cedrus, picea are examples of gymnosperm plants.
