The ultrastructure of cells

The of a cell is its fine structure as revealed at high magnification. Animal, fungal and plant cells all contain structures called . These are specialised for particular functions .

The diagrams below show the similarities and differences between the ultrastructure of animal cells and plant cells.

Animal and plant cells. Both share cytoplasm, nucleus, ribosome, mitochondrion and cell membrane. Plant cells have chloroplast, vacuole and cell wall.
