Question

Which of these could explain why flowering plants rapidly evolved from simple forms to more complex, diverse forms? Group of answer choices The climate at the time of divergence from gymnosperms was suitable for the rapid evolution of flowering forms Co-evolution between insects and flowering plant allowed rapid divergence among flowering plants The relationship between insects and flowering plants increased the fitness of the plants Animals enhance both pollination and seed dispersal in plants All of these are possible explanations for the evolution of flowering plants

Answer 1

Answer:

The answers are B and D.

Explanation:

The co-evolution of plants and insects led to an increase in both populations due to the mutualist benefit of this relationship. As plants started to develop rewards for the insects (such as pollen and nectar) the insects started to be able to travel further and therefore colonize, then as diversification of flowers began, also the insects started to diversify in order to afford the vast amount of food for them. Insects helped plants to pollinate and plants helped insects to spread. But as insects were evolving, some mammals and birds were also doing so, therefore, plants developed fruits with seeds in order to increase their dispersal. As answer D exposes, animals not only enhanced pollination but they also provided seed dispersal.
