Question

Perisperm present in seed of black pepper is remnant of

• A. Ovary
• B. Nucellus
• C. Anther
• D. Megaspore

Hint:

Perisperm is the left-over nucellus found in seeds such as black pepper and beet.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
After fertilisation, the endosperm usually feeds the embryo and is used up. In some seeds, part of the nucellus is left over.
This left-over, persistent nucellus is called perisperm.

Step 2: Link to black pepper:
Black pepper and beet are examples of seeds that have perisperm. It is a non-endosperm food tissue made from the nucellus.

Step 3: Check option (A) Ovary:
The ovary wall becomes the pericarp of the fruit, not the perisperm. So (A) is wrong.

Step 4: Check option (B) Nucellus:
The nucellus is the diploid tissue of the megasporangium. Its remnant is the perisperm. So (B) is right.

Step 5: Check options (C) and (D):
The anther is a male part and belongs to the stamen, so (C) is wrong.
The megaspore forms the embryo sac and gives rise to the female gametophyte, not the perisperm. So (D) is wrong.

Final Answer:
Perisperm is the persistent remnant of the nucellus, which is option (B).
