Question

Companion cells are

• A. small, thin walled living, enucleated
• B. living, narrow, elongated, thin walled, nucleated
• C. small, thick walled, living, nucleated
• D. large, thick walled, nucleated

Answer 1

The correct option is A small, thin walled living, enucleated

Companion cells are the constituents of Phloen tissues which conduct the transport of food and minerals. Their position is adjacent to sieve elements (Type of phloem tissues which are responsible for the transportation of nutrients) and helps in the flow of sugars. They are structurally small, thin-walled cells and are enucleated, they die when are broken. They are the living cells of the phloem.

So, the correct option is 'Small, thin walled living, enucleated'.
