Rewards and attractants are required fora)Entomophilyb)Cleistogamyc)Anemophilyd)HydrophilyCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

Entomophily means pollination by insects. Anemophily means wind pollination, Hydrophily is water pollination. Cleistogamy is seen in closed flowers which never open. So this is a type of autogamy.

Answer

Correct answer is A

Answer

A

Answer

Entomophily requires rewards and attractants
Entomophily is the process of pollination by insects, such as bees, butterflies, and beetles. In order to attract these insects to pollinate the flowers, rewards and attractants are required.
- Rewards: Insects are attracted to flowers that offer rewards in the form of nectar, pollen, or other substances that provide nutrition. These rewards serve as an incentive for the insects to visit the flowers and transfer pollen from one flower to another.
- Attractants: Flowers use attractants such as bright colors, patterns, and fragrances to attract insects. These visual and olfactory cues help the insects locate the flowers and identify them as a potential food source. By providing both rewards and attractants, plants increase the likelihood of successful pollination by attracting a diverse range of insect pollinators.
In the absence of rewards and attractants, insects may not be motivated to visit the flowers, resulting in reduced pollination success. Therefore, for entomophily to occur effectively, plants must provide both rewards and attractants to attract insect pollinators.

Answer

A) Cleistogamy - It is a type of self-operating pollination technique of some plants. They are propagated by using non-opening, self-pollinating flowers. So they do not need any attractants and rewards. Thus it is the wrong answer.
B) Anemophily – it is wind pollination. Here pollen is distributed by wind. So they also do not need attractants/rewards. It is the wrong option.
C) Entomophily – it is insect pollination. Here pollen is carried by an insect. Insects are attracted by the attractants of plants and spores are distributed by them. So here attractants and rewards are required for pollination. Thus it is the correct option.
D) Hydrophily – Here pollen is distributed by the water flow. Thus it has no requirement for attractants and rewards. So it is the wrong option.
