Which one of the following statements about vacuoles' is not correct?

A.
In plants, there is a large central vacuole that may occupy 90% of total cell volume.
B.
In plant cells, vacuoles provide turgidity and rigidity.
C.
In Amoeba, vacuoles have role in nutrition.
D.
Vacuoles are absent in animal cells.

Solution:

The correct answer is Vacuoles are absent in animal cells (incorrect).Explanation:Vacuoles are large membrane sacs found in the cytoplasm.These store substances that are not essentially useful for the cell (like water, sap, excretory product, and other materials).In plants, there is a large central vacuole that may occupy 90% of the total cell volume. Hence statement 1 is correct.Vacuoles in plant cells are very large and can occupy up to 90% of the volume of the cell. The vacuole is surrounded by a membrane called tonoplast.In-plant cells, vacuoles provide turgidity and rigidity. Hence statement 2 is correct.Plant cells have typically large central vacuoles filled with a watery fluid that gives added support to the cell and also provides turgidity and rigidity to the plant cell.In Amoeba, vacuoles have a role in nutrition. Hence statement 3 is correct.A food vacuole is a membrane-enclosed sac that performs digestive functions.They are found in the cells of protozoan protists such as amoeba and plasmodium.They function as an intracellular stomach, digesting the food consumed.Vacuoles are absent in animal cells. Hence statement 4 is not correct.Animal cells have more vacuoles than plant cells, but they are much more prominent in case of plant cells. Vacuoles in animal cells are smaller in size than the vacuoles in plant cells.
