Question

Totipotency is present in ------------------------

• A. Meristem
• B. Cambium
• C. Phloem
• D. Cork

Answer 1

The correct option is A

Meristem

The correct option is A.

Explanation of the correct option:

1. Totipotency is defined as the ability of a single cell to undergo division and produce differentiated cells that can develop into a new whole plant.
2. Meristems are the tissues that can divide continuously, and thus totipotency is present in them.

Explanation of the incorrect option:

Option B:

1. Cambium is a tissue layer that is present underneath the bark of a woody tree or plant, and they divide to perform a particular function like redifferentiation. Thus totipotency is absent.

Option C:

1. Phloem is a permanent tissue and thus cannot divide cells.

Option D:

1. Cork are rectangular-shaped dead cells and cannot divide cells.

Final answer:

1. Totipotency is present in meristem.
