The correct reason why animal cells don't need a central vacuole is because animal bodies have skeletons or other means of providing structure.
The options provided are not all correct. The correct options are:
1. Animal bodies have skeletons or other means of providing structure.
Explanation: Unlike plant cells, animal cells have specialized structures such as bones, cartilage, and muscles that provide support and structure to the body. These structures eliminate the need for a large central vacuole, as they fulfill the role of supporting the body.
2. Animals do not produce their own food.
Explanation: Animals are heterotrophs, which means they obtain their nutrients by consuming other organisms. Unlike plants, animals do not have the ability to photosynthesize and produce their own food. Therefore, the presence or absence of a central vacuole is not related to their mode of obtaining nutrition.
3. Animal cells do not have cell walls.
Explanation: One major difference between plant and animal cells is the presence of a cell wall. Plant cells have a rigid cell wall made of cellulose, which provides support and protection. On the other hand, animal cells lack a cell wall and rely on other structural elements, such as the cytoskeleton and extracellular matrix, for stability and shape. The absence of a cell wall in animal cells also eliminates the need for a large central vacuole.
4. Animal cells can have different shapes.
Explanation: Animal cells can have various shapes depending on their function. While some animal cells may be round, others can be irregularly shaped or have specialized structures, such as nerve cells with long extensions. The shape of an animal cell is not directly related to the presence or absence of a central vacuole.
