Step 1: Understanding pseudocopulation.
- Pseudocopulation is a process in which a male insect is attracted to a flower that mimics the appearance or scent of a female insect.
- During its attempt to copulate, the insect facilitates pollination by transferring pollen.
Step 2: Mimicry in flowers. - This is an example of mimicry used by flowers to attract specific pollinators, ensuring effective reproduction.
Match the pollination types in List-I with their correct mechanisms in List-II:
List-I (Pollination Type) | List-II (Mechanism) |
---|---|
A) Xenogamy | I) Genetically different type of pollen grains |
B) Ophiophily | II) Pollination by snakes |
C) Chasmogamous | III) Exposed anthers and stigmas |
D) Cleistogamous | IV) Flowers do not open |
Many of the flowering plants producing hermaphrodite flowers have developed many devices to discourage self-pollination and to encourage cross-pollination. Given below is a picture of one such outbreeding device in a flowering plant. Study the picture and answer the questions that follow:
(a) Explain how the given type of pollination is advantageous to the plant.
(b) Can this flowering plant show geitonogamy? Justify your answer.
Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Both wind and water pollinated flowers are not very colorful and do not produce nectar.
Reason (R): The flowers produce enormous amounts of pollen grains in wind and water pollinated flowers.
In light of the above statements, choose the correct answer from the options given below:
