May 19, 2024 · An animal cell is a eukaryotic cell that lacks a cell wall, and it is enclosed by the plasma membrane. The cell organelles are enclosed by the plasma membrane including the cell nucleus. Unlike the animal cell lacking the cell wall, plant cells have a cell wall.
Although animal cells can vary considerably depending on their purpose, there are some general characteristics that are common to all cells. These include structures such as the plasma membrane, cytoplasm, nucleus, mitochondria, and ribosomes.
Feb 28, 2021 · These figures show the major organelles and other cell components of (a) a typical animal cell and (b) a typical eukaryotic plant cell. The plant cell has a cell wall, chloroplasts, plastids, and a central vacuole—structures not found in animal cells.
