Eläinsolulla

Eläinsolulla is a Finnish term that translates to "animal cell" in English. It refers to the basic structural and functional unit of all animal tissues. Like other eukaryotic cells, animal cells are characterized by the presence of a nucleus, which contains the cell's genetic material, and various membrane-bound organelles that perform specific functions. These organelles include mitochondria for energy production, ribosomes for protein synthesis, the endoplasmic reticulum for protein and lipid modification, and the Golgi apparatus for further processing and packaging of molecules.

Animal cells lack a cell wall, which is a common feature of plant and fungal cells. This absence allows for greater flexibility and movement, enabling cells to form complex tissues and organs. The outer boundary of an animal cell is the plasma membrane, a selectively permeable barrier that regulates the passage of substances into and out of the cell. Animal cells also often have a cytoskeleton, a network of protein filaments that provides structural support, maintains cell shape, and plays a role in cell division and movement. The variety of cell types in animals, such as nerve cells, muscle cells, and blood cells, reflects their specialized functions and adaptations.
