Which one of the following statements about Vacuoles’ is not correct?
Explanation
Vacuoles are membrane-bound organelles present in both plant and animal cells, though their characteristics differ significantly. In plant cells, a large central vacuole often occupies up to 90% of the total cell volume. These vacuoles are crucial for maintaining turgor pressure, which provides turgidity and rigidity to the plant cell [1]. In single-celled organisms like Amoeba, vacuoles play a vital role in nutrition; specifically, food vacuoles are formed when the cell membrane fuses over food particles [3]. While animal cells do contain vacuoles, they are typically much smaller and often temporary compared to the large, permanent central vacuoles found in plants [1]. Therefore, the statement that vacuoles are absent in animal cells is incorrect, as they are present but less prominent [3].
