Detailed explanation-1: -The success of angiosperms is due to two novel reproductive structures: flowers and fruit. The function of the flower is to ensure pollination. Flowers also provide protection for the ovule and developing embryo inside a receptacle.

Detailed explanation-2: -Answer and Explanation: Angiosperms have several adaptations that make them successful on land including smaller, lighter pollen grains that can be easily distributed by the wind. They also have stamen to produce pollen and small female reproductive structures that allow them to quickly produce lots of seeds.

Detailed explanation-3: -Pollen and ovule are reproductive parts of angiosperms. The ovary is located in the flower. Ovules develop into seeds after fertilization.

Detailed explanation-4: -Flowers are unique to angiosperms and they act as its reproductive organs producing male and female haploid gametes often in the same flower.

Detailed explanation-5: -Angiosperms and gymnosperms both utilize seeds as the primary means of reproduction, and both use pollen to facilitate fertilization. Gymnosperms and angiosperms have a life cycle that involves the alternation of generations, and both have a reduced gametophyte stage.
