NEET BIOLOGY

Detailed explanation-1: -Angiosperms and gymnosperms both utilize seeds as the primary means of reproduction, and both use pollen to facilitate fertilization.

Detailed explanation-2: -Unlike gymnosperms such as conifers and cycads, angiosperm’s seeds are found in a flower. Angiosperm eggs are fertilized and develop into a seed in an ovary that is usually in a flower. The flowers of angiosperms have male or female reproductive organs.

Detailed explanation-3: -The stamens produce the male gametes in pollen grains. The carpels contain the female gametes (the eggs inside the ovules), which are within the ovary of a carpel. The walls of the ovary thicken after fertilization, ripening into fruit that ensures dispersal by wind, water, or animals.

Detailed explanation-4: -Both groups produce seed, but the seed of angiosperms is enclosed within a fruit. The names are from Greek – gymnosperm meaning “naked seed, ” angiosperm combining “vessel” and “seed”.

Detailed explanation-5: -Angiosperms are plants that produce flowers and fruit. Angiosperms can be self-pollinated, meaning pollen falls on the stigma of the same flower, or cross-fertilized, during which pollen from one flower travels to a stigma of a flower on another plant.
