NEET BIOLOGY

Detailed explanation-1: -Features that are unique to angiosperms and which help account for their success are C) Fruits enclosed within seed coats. Angiosperms are plants that produce flowers, and after fertilization occurs, the ovary of the flower develops into a fruit.

Detailed explanation-2: -Brodribb and Feild argue that more photosynthesis meant more carbon for growth. And that would have given the angiosperms the energy to push competitors like conifers out of the canopy around 150 million years ago, making angiosperms the most productive group of land plants in the world.

Detailed explanation-3: -Angiosperms are the only plants that have concealed seeds. The seeds in angiosperms are found inside the fruit. The fruit protects the seed and also gives nutrition. No other division in the plant kingdom bears fruits.

Detailed explanation-4: -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. The function of the fruit is seed dispersal.

Detailed explanation-5: -Angiosperms are the dominant form of plant life in most terrestrial ecosystems, comprising about 90 percent of all plant species. Most crop and ornamental plants are angiosperms. Their success results, in part, from two innovative structures: the flower and the fruit.
