AP BIOLOGY

Detailed explanation-1: -Gymnosperms are the seed-producing plants, but unlike angiosperms, they produce seeds without fruits. These plants develop on the surface of scales or leaves, or at the end of stalks forming a cone-like structure.

Detailed explanation-2: -Gymnosperms. These seed plants do not have flowers or fruit-their seeds are held in cones. Next time you pick up a pine cone, look for loose seeds inside. Male cones make pollen, which is carried to female cones by the wind.

Detailed explanation-3: -The seed plants are often divided arbitrarily into two groups: the gymnosperms and the angiosperms. The basis for this distinction is that angiosperms produce flowers, while the gymnosperms do not.

Detailed explanation-4: -Depending upon whether the seeds are enclosed in fruit or not, plants are classified as gymnosperms (naked-seeds) and angiosperms (seeds covered by fruit) Depending upon the number of cotyledons in seeds, plants are classified into dicotyledons and monocotyledons.
