Question

Megasporangium is equivalent to

• A. Ovule
• B. Embryo sac
• C. Fruit
• D. Nucellus

Answer 1

The Correct Option is A

The question asks about the equivalence of a "megasporangium". Let's explore the given options to determine the correct answer:

1. Ovule: In seed plants, the megasporangium is present within the ovule. The ovule undergoes development and eventually becomes a seed after fertilization. Thus, the ovule contains the megasporangium and is indeed equivalent to it in this context.
2. Embryo Sac: The embryo sac is the female gametophyte within the ovule. It develops as a result of meiosis and mitosis from the megaspore, not the megasporangium itself. Therefore, the embryo sac is not equivalent to the megasporangium.
3. Fruit: The fruit is a mature ovary that houses seeds and is not related to the megasporangium directly. Hence, fruit is not equivalent to megasporangium.
4. Nucellus: The nucellus is a tissue within the ovule that surrounds the megasporangium. Although closely associated, it is not equivalent to the megasporangium itself.

Based on these explanations, the correct answer is the ovule, as it directly encompasses the megasporangium in seed plants.
