All animals are multicellular organisms and their basic unit is the eukaryotic cell. It differs from the prokaryotic cell, typical of the organisms of the Monera kingdom, mainly by the presence of a differentiated nucleus surrounded by a nuclear membrane. Eukaryotic cells also have the ability to form multicellular organisms and coexist with different types of cells specialized in specific functions within complex living beings.
If you want to learn much more about the cells that make up the basis of the living beings of the kingdom Animalia , continue reading this summary on the parts of the animal cell and their functions.
What is the animal cell
The animal cell is the base cell in living beings that are part of the kingdom Animalia , that is, animals. There are different types or specializations, depending on the functions they must perform in each part of the body. Examples of animal cells with diverse shapes and functions are neurons in the nervous system, leukocytes in the immune system, and eggs and sperm in the reproductive system, among many others. For example, a human being has more than 200 different types of cells.
Animal cells are distinguished from plant cells by having a smaller diameter and by not having a cell wall and chloroplasts. The shapes, sizes and functions of animal cells are very varied but, in general and as we have indicated, they have a smaller diameter than plant cells. Many are specialized to perform a specific function: detect and communicate sensations, create support tissues, etc.
