Question

A single large central vacuole occurs in
A. Mature animal cells
B. Mature plant cells
C. Developing animal cells
D. Developing plant cells

Answer 1

Hint: A cell is the unit of life. It has various organelles carrying out the functions of our life. From the protein synthesis to the import and export of materials from the cell, everything is organized in a cell. Some are membrane-bound while some are not. Their number varies from the function and requirement.

Complete answer:
What is a vacuole? They are the bubbles found in animal and plant cells, which store the food or nutrients. They can also have the waste products to protect the cell from the contamination
Let us see the options now.
Option A: Mature animal cell: They have a larger number of vacuoles in a cell. Their main function is to store nutrients and food.
Option B: Mature plant cell: The mature plant cell has a large vacuole which is present in the centre of the cell. It is membrane (tonoplast). It has water filled in it and dissolved enzymes. It is the characteristic feature of a plant cell. Their main function in plants is to maintain the water balance.
Option C: Developing animal cell: Vacuoles are found only in the developed and matured cells.
Option D: Developing plant cell: Vacuoles are present in the matured cells only.

So the answer is option B: Mature plant cell.

Note: Vacuoles have no size and shape. The cell can change them according to the work. They are mostly present in the eukaryotic cells. They are the closed organelles with a membrane. It contains both organic and inorganic enzymes in them.
