Difference Between Angiosperm & Gymnosperm

Edited By Irshad Anwar | Updated on Jul 02, 2025 05:23 PM IST

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.

What Are Angiosperms And Gymnosperms?

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.
