Which statement about vacuoles is true?
Understanding Vacuoles
Vacuoles are membrane-bound organelles that are found in cells of plants, fungi, protists, and some animal cells. They are essentially bags filled with liquid or air that serve various functions such as storage, waste disposal, and defense mechanisms. Vacuoles play a crucial role in maintaining the overall structure and support of plant cells.
Differences in Vacuoles between Plant and Animal Cells
Plant cells: In plant cells, vacuoles are significantly larger and more noticeable compared to animal cells. They can occupy up to 90% of the cell volume and are essential for maintaining cell pressure, which is important for plant support and structure. Plant cell vacuoles also store waste materials, pigments, and nutrients.
Animal cells: On the other hand, vacuoles in animal cells are smaller and less prominent. They serve similar functions but are not as critical for cell structure and support. Animal cell vacuoles are primarily involved in storage and waste disposal.
Overall, vacuoles are vital organelles that play a crucial role in the functionality and maintenance of plant cells, with notable differences in size and prominence compared to animal cells.
