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:
Aakash and Baadal entered into partnership on 1st October 2023 with capitals of Rs 80,00,000 and Rs 60,00,000 respectively. They decided to share profits and losses equally. Partners were entitled to interest on capital @ 10 per annum as per the provisions of the partnership deed. Baadal is given a guarantee that his share of profit, after charging interest on capital, will not be less than Rs 7,00,000 per annum. Any deficiency arising on that account shall be met by Aakash. The profit of the firm for the year ended 31st March 2024 amounted to Rs 13,00,000.
Prepare Profit and Loss Appropriation Account for the year ended 31st March 2024.
