Question

Meristematic tissues divide repeatedly. What property of their cells allows them to do this?

Options

• They have thick walls for protection.

• They contain large vacuoles that store nutrients.

• They have thin walls, dense cytoplasm and large prominent nucleus.

• They are functionally differentiated cells.

Answer 1

They have thin walls, dense cytoplasm and large prominent nucleus.

Explanation:

Thin walls allow cells to expand and divide, thick cytoplasm with many organelles promotes active metabolism, and a huge, conspicuous nucleus controls cell division. Vacuoles are lacking to keep cells tiny and divide quickly. Other ideas are wrong because thick walls prohibit division, meristematic cells lack big vacuoles, and functionally differentiated cells cannot divide.
