Which of the following statements is true?

Understanding Vacuoles in Animal and Plant Cells

Vacuoles are membrane-bound organelles found in the cells of both plants and animals. These vacuoles play crucial roles in maintaining the cell's structure, storage, and waste management.

All animal cells have at least one vacuole, but only some plant cells have vacuoles: This statement is incorrect. While it is true that all animal cells contain vacuoles, it is also true that all plant cells have vacuoles as well. Vacuoles are essential organelles in plant cells and are responsible for various functions, including storing nutrients, maintaining turgor pressure, and storing waste materials.

Only a few animal and plant cells have vacuoles: This statement is also incorrect. Vacuoles are present in the majority of animal and plant cells, and they are essential for the survival and proper functioning of the cells.

All plant cells have at least one vacuole, but only some animal cells have vacuoles: This statement is partially correct. While all plant cells do contain vacuoles, it is not true that only some animal cells have vacuoles. In fact, all animal cells have at least one vacuole, albeit their size and function may vary.

In conclusion, vacuoles are present in both animal and plant cells, playing vital roles in maintaining cell function and structure. Therefore, option B is the correct answer to the question.
