One reason animal cells don't need a central vacuole is because they often have smaller vacuoles for storage. What is another reason animal cells don't need central vacuoles?
Animals do not produce their own food.
Animal cells have cell walls.
Animal bodies have skeletons or other means of providing structure.
Animal cells are often specialized for specific functions, such as muscle contraction or nerve impulse transmission, that do not require a central vacuole.
But which one is it?
Animal cells do not have cell walls.
Which one is it A B or c?
C) Animal bodies have skeletons or other means of providing structure.
The correct answer is that animal cells do not have cell walls. Unlike plant cells, animal cells do not possess a rigid cell wall made of cellulose. Instead, animal cells are surrounded by a flexible cell membrane that allows for movement and changes in cell shape. The absence of a cell wall is one of the key reasons why animal cells do not require a central vacuole.
To understand this concept, it helps to have a basic understanding of the role and function of a vacuole. Vacuoles are membrane-bound structures found within cells. They play various roles in different organisms, including storage of water, nutrients, waste products, and other substances. In plant cells, the central vacuole is responsible for maintaining turgor pressure, storing water, and providing structural support, among other functions.
However, animal cells have evolved different mechanisms to fulfill these functions. For example, animals obtain water and nutrients from their environment through ingestion, rather than relying on a central vacuole. They have specialized systems such as the digestive system that break down and absorb nutrients from food. Additionally, animal bodies have different structures to provide support and maintain shape, such as skeletons (invertebrates and vertebrates) or an exoskeleton (arthropods).
In summary, animal cells do not have central vacuoles because they do not have a cell wall and have evolved alternative mechanisms to perform functions such as nutrient storage, water regulation, and structural support.
