Animal cells and plant cells are both eukaryotic. Thus, they both have a defined nucleus and other membrane-bound organelles. However, animal and plant cells also have some fundamental differences.
Animal cells, unlike plant and fungi cells, do not have a cell wall. Instead, multicellular animals have other structures that provide support to their tissues and organs, such as skeleton and cartilage. Additionally, animal cells also lack chloroplasts found in plant cells. Chloroplasts are specialized organelles that trap energy from the sun and use it as fuel to produce sugars in a process called photosynthesis.
Additionally, while plant cells tend to have a large, central vacuole, animal cells lack this feature. Some animal cells do have small vacuoles, but their function is to assist in the storage and transport of large molecules.
