Types of cell

All living organisms are made of small units called .

Multicellular

Organisms made of more than once cell are described as multicellular. Examples of multicellular organisms include animals and most species of plants.

The following diagram shows the variety of human cell types.

The variety of human cell types: epithelial cells, leucocyte, liver cell, nerve cell, fat cell, cartilage cell, striated muscle fibre, human cell, bone cell and smooth muscle cell.

Unicellular

Organisms such as bacteria and yeast are described as unicellular as they exist as single cells.

The component parts of bacterial and yeast cells. The bacterial cell has a cell wall, cell membrane, molecule of circular DNA and cytoplasm. The yeast cell has cell wall, cell membrane, nucleus, cytoplasm and mitochondria.
