There are 13 main parts of an animal cell: cell membrane, nucleus, nucleolus, nuclear membrane, cytoplasm, endoplasmic reticulum, Golgi apparatus, ribosomes, mitochondria, centrioles, cytoskeleton, vacuoles, and vesicles.
Animal cells range in size from a few microscopic microns to a few millimetres. The largest known animal cell is the ostrich egg, which can stretch over 5.1 inches across and weighs about 1.4 kilograms. This is in stark contrast to the neuron in the human body, which is just 100 microns across.
Feb 2, 2023 · Parts of an Animal Cell. Animal Cell Diagram. 1) Centrioles. They are paired tube-like organelle composed of a protein called tubulin. Centrioles are about 500nm long and 200nm in width that are found close to the nucleus and helps in cell division. They are also found in cilia and flagella. Functions.
Plant cells do indeed have chloroplasts while animal cells do not, but both types of cells have mitochondria. Animal cells have structures called lysosomes (which are basically organelles containing an extremely acidic fluid to break down objects) and centrosomes (used in cell reproduction).
May 9, 2023 · Here is a list of animal cell components and organelles and their functions: Cell Membrane: The cell membrane or plasma membrane is a selectively permeable lipid bilayer that encloses the contents of the cell and regulates the transport of materials into and out of it.
