One reason animal cells don't need a central vacuole is because

Answer 1

they have multiple small vacuoles dispersed throughout the cytoplasm. These small vacuoles perform similar functions to a central vacuole in plants, such as storing water, ions, nutrients, and waste products. Animal cells also have other specialized organelles, such as lysosomes, which help in the digestion and breakdown of cellular waste materials. Therefore, the presence of multiple smaller vacuoles, along with other organelles, allows animal cells to effectively carry out their functions without the need for a central vacuole.
