Question

Choose the correct statements related to plant reproduction
I. In Cladophora, male and female gametes are morphologically similar
II. Male and female gametes of Pteris are heterogametes
III. Fungi are usually homothallic and unisexual
IV. Monoecious plants are bisexual

• A. I, II, IV
• B. I, II, III
• C. II, III, IV
• D. I, III, IV

Hint:

When studying plant reproduction, remember that monoecious plants have both male and female reproductive organs on the same plant, while dioecious plants have male and female organs on separate individuals.

Answer 1

The Correct Option is A

Let's analyze each statement:

• Statement I: "In Cladophora, male and female gametes are morphologically similar." This statement is correct. In some species of Cladophora (a type of algae), the male and female gametes are morphologically similar and are called isogamous.
• Statement II: "Male and female gametes of Peris are heterogametes." This statement is correct. In some species like Peris (a type of algae), the male and female gametes are different in shape and are called heterogametes.
• Statement III: "Fungi are usually homothallic and unisexual." This statement is incorrect. Fungi are typically heterothallic (requiring two compatible mating types for sexual reproduction), and they can be either unisexual or bisexual.
• Statement IV: "Monoecious plants are bisexual." This statement is correct. Monoecious plants have both male and female reproductive organs on the same individual, making them bisexual.

Thus, the correct answer is: (1) I, II, IV.
