Question

When anthers and stigma mature at the same time, it is called as-
A. Protandry
B. Homogamy
C. Isogamy
D. Dichogamy

Answer 1

Hint: The act of transporting pollen grains from the male flower to the female bloom is referred to as pollination. As we know pollination is nothing but a method of reproduction, the goal of every organism so as in plants also is to create offspring for the next generation. Plants can reproduce in a variety of ways, including by transferring seeds from opposite sex blooms.

Complete answer:
Option A: Protandry- protandry is the condition where a male flower matures first and then female flower in later stages.
Option A is not the correct answer.
Option B: Homogamy- homogamy is the condition where a male flower and female flower matures at the same time. It is an action of self-pollination.
Option B is the correct answer.
Option C: Isogamy- isogamy is the condition in which gametes are similar to each other in shape, size and structure.
Option C is not the correct answer.
Option D: Dichogamy- in dichogamy self-fertilization cannot take place. It is the condition where anther and stigma mature at different times.
Option D is not the correct answer.

Hence, Option B is the correct answer.

Note:
Agents who usually help in pollination are called pollinating agents. Animals, birds, insects, wind, and other factors can all act as pollinators. They are divided into two groups based on their way of life. A- abiotic B-biotic. Pollination by wind or water is an example of an abiotic factor. This type of pollination through an abiotic medium is called wind pollination and water pollination.
