Furthermore, animal cells rely on cell-cell junctions such as tight junctions, desmosomes, and gap junctions to connect with neighboring cells and provide structural support. These junctions help maintain tissue integrity and allow for communication between cells.
Overall, the absence of a cell wall and central vacuole in animal cells allows for greater flexibility, mobility, and specialization in function. This allows animal cells to perform diverse functions throughout the body and adapt to changing environments.
Animal cells do not require a cell wall because they rely on support from their cytoskeleton, a network of protein filaments that provides structural support and helps maintain cell shape. Animal cells also do not require a central vacuole because they have organelles such as lysosomes and peroxisomes that perform similar functions. Additionally, animal cells do not need a cell wall or central vacuole to maintain proper turgor pressure or to store nutrients, as these functions are accomplished through other means such as ion channels and specialized organelles like mitochondria.
