Identify the correct statement regarding the edible part of a coconut.
It is the pericarp.
It is diploid (2n) in nature.
It is the embryo.
It is triploid (3n) in nature.
In a coconut, the liquid 'coconut water' and the solid 'coconut meat' are derived from which parts, respectively?
Liquid endosperm, Embryo
Liquid endosperm, Solid endosperm
Embryo, Solid endosperm
Embryo, Pericarp
Which of the following is NOT a part of the coconut fruit that is typically consumed?
Endosperm
Coconut water (liquid endosperm)
Coconut meat (solid endosperm)
Seed coat
Which of the following statements is INCORRECT regarding pollination?
Pollination is the transfer of pollen from anther to stigma.
Pollination always leads to fruit development.
Cross-pollination introduces genetic diversity.
Wind and insects can act as pollinating agents.
Which of the following is NOT a direct outcome of successful pollination?
Fertilization
Seed development
Fruit development in all plants
Transfer of pollen to the stigma
Pollination is essential for: I. Seed formation II. Fruit development in all plants III. Genetic variation in cross-pollinating species IV. Transfer of pollen from anther to stigma
I and II only
II and III only
I, III, and IV only
I, II, III, and IV
A plant species exhibiting parthenocarpy will:
Require pollination for fruit development
Develop fruit without pollination
Not produce seeds
Always undergo self-pollination
Given below are two statements:
Statement I: Cleistogamous flowers are always autogamous.
Statement II: Cleistogamy is disadvantageous as there is no chance for cross pollination.
In the light of the above statements, choose the correct answer from the options given below:
Both Statement I and Statement II are correct
Both Statement I and Statement II are incorrect
Statement I is correct but Statement II is incorrect
Statement I is incorrect but Statement II is correct
Cleistogamous flowers are known for:
(i) Never opening
(ii) Self-pollination
(iii) Promoting genetic diversity
(iv) Requiring pollinating agents
Choose the correct combination:
(i) and (ii)
(ii) and (iii)
(iii) and (iv)
(i) and (iv)
Which of the following is a disadvantage of cleistogamy?
Lack of genetic variation
Assured seed set
No dependence on pollinators
Conserves energy
