NEET BIOLOGY

Detailed explanation-1: -Angiosperms, also called flowering plants, have seeds that are enclosed within an ovary (usually a fruit), while gymnosperms have no flowers or fruits, and have unenclosed or “naked” seeds on the surface of scales or leaves. Gymnosperm seeds are often known as cones.

Detailed explanation-2: -In angiosperms, the female gametophyte exists in an enclosed structure-the ovule-which is within the ovary; in gymnosperms, the female gametophyte is present on exposed bracts of the female cone. Double fertilization is a key event in the lifecycle of angiosperms, but is completely absent in gymnosperms.

Detailed explanation-3: -The key difference between angiosperms and gymnosperms is how their seeds are developed. The seeds of angiosperms develop in the ovaries of flowers and are surrounded by a protective fruit. Gymnosperm seeds are usually formed in unisexual cones, known as strobili, and the plants lack fruits and flowers.

Detailed explanation-4: -Gymnosperms are the plants which are characterized by the naked seeds. Seeds develop on the scale of the leaf or in the modified cones. In the Angiosperm plant, the embryo is covered in a hard coating called as a seed. The seeds have endosperm which provides nutrition to the developing embryo.

Detailed explanation-5: -The ovules in angiosperms are encased in an ovary, not exposed on the sporophylls of a strobilus, as they are in gymnosperms. Angiosperm means “covered seed". The ovules develop into seeds, and the wall of the ovary forms a fruit to contain those seeds. Fruits attract animals to disperse the seeds.
