Why do animal cells not have central vacuoles (explain in 7th grade way)
In simpler terms, animal cells don't have central vacuoles because they have different needs and functions compared to plant cells. Plant cells have a large central vacuole that helps them store water, nutrients, and waste. It also helps maintain the shape of the plant.
On the other hand, animals get their water and nutrients from the food they eat and the fluids they drink. They don't need a central vacuole to store these things because their bodies can process and use them right away. Animals also don't need a centralized storage area for waste, as they have different ways of getting rid of it, such as through the kidneys or intestines.
So, in summary, animal cells don't have central vacuoles because they have different systems in place to get and use water, nutrients, and waste.
