Cells are microscopic building blocks of unicellular and multicellular living organisms. Animal, plant, fungal and bacterial cells are different in terms of structure but also have many similarities.

Structure of fungal and bacterial cells

Fungal cells

A yeast is a unicellular fungus. The diagram below shows the ultrastructure of a typical yeast cell:

A yeast cell showing cytoplasm, the small ribosomes, the larger mitochondrion, nucleus, cell wall and cell membrane.

Bacterial cells

have a more simple structure compared to animal, plant and fungal cells and are usually much smaller.

They still have a and , but they lack organelles such as the .

However, bacteria still have DNA, including extra circular pieces of DNA called plasmids.Their is made of a diffferent material and has a different structure to those of plant and .
