NEET BIOLOGY

Detailed explanation-1: -Answer and Explanation: 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: -Angiosperm success is a result of two novel structures that ensure reproductive success: flowers and fruit. Flowers allowed plants to form cooperative evolutionary relationships with animals, in particular insects, to disperse their pollen to female gametophytes in a highly targeted way.

Detailed explanation-4: -First, their leaves have more stomata than other types of plants, allowing them to take in more carbon dioxide and produce more food through photosynthesis.

Detailed explanation-5: -Angiosperms are the dominant form of plant life in most terrestrial ecosystems, comprising about 90 percent of all plant species. Most crops and ornamental plants are angiosperms. Their success comes from two innovative structures that protect reproduction from variability in the environment: the flower and the fruit.
