A cell is an elementary structural and functional unit of living things.
Animal cell structure:
The nucleus contains genetic information and controls the life of the cell.
The cytoplasm is the internal environment of the cell, where various processes take place and the components of the cell – organelles – are located.
The endoplasmic reticulum is involved in the synthesis of cell proteins.
The Golgi apparatus takes part in the transformation of cell proteins and synthesizes lysosomes – the digestive organelles of the cell.
Mitochondria convert nutrients into energy.
Lysosomes are organelles of fungi and animals that are absent in plant cells. Possessing the ability to actively digest nutrients, the lysosome is involved in the removal of parts of cells, whole cells and organs dying off in the process of vital activity.
The cell center takes part in cell division, thereby ensuring its reproduction.
The cell is delimited from the environment by the cytoplasmic membrane. Animal cells do not have a cell wall.
