The shape of a typical animal cell varies widely from being flat, oval to rod-shaped, while others assume shapes such as curved, spherical, concave, and rectangular. An animal cell ranges in size from 10 to 30 µm. Under the microscope, an animal cell shows many different parts called organelles, that work together to keep the cell functional.
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.
Get animal cell facts, including a labeled cell diagram, a list of organelles and their functions, and a summary of animal cell types.
Overview of Animal Cells. Animals, plants, fungi, and protists are all made up of at least one eukaryotic cell. In contrast, bacteria and archaea are made up of a single prokaryotic cell. All cells are surrounded by a cell membrane (also called a plasma membrane).
A labeled diagram of an animal cell, and a glossary of animal cell terms. Learn about the different parts of a cell.
Animal cells are eukaryotic cells, mostly multicellular containing cytoplasm and membrane-bounded organelles enclosed within the plasma membrane. The animal kingdom contains the largest number of species on the entire earth.
Nucleus. The nucleus is referred to as the cell’s control center. It contains genetic material (DNA) that regulates various cell activities and protein synthesis. Nuclear Membrane. The nucleus is surrounded by double membrane. It controls the passage of substances between the nucleus and the cytoplasm. Centrosome.
