Biology

The structures inside of cells are known as sub-cellular structures
In an animal cell, the sub-cellular structures include:

• a nucleus, which controls the activities of the cell and contains the genetic information
• cytoplasm, where most of the chemical reactions occur
• a cell membrane, which controls the passage of substances into and out of the cell
• mitochondria, where aerobic respiration occurs
• ribosomes, where proteins are synthesised

In plant and algal cells, the sub-cellular structures include:
