The structure of a fungal cell is similar to that of a plant cell. However, fungal cells do not have photosynthetic chloroplasts.

Like all other living organisms, fungi consist of cells. Fungal cells are similar to plant cells, but they lack their photosynthetic chloroplasts. Because of this, fungi are not capable of photosynthesis.

Fungi cells are joined together into branching mycelia. These mycelia grow in large quantities in the forest soil and in rotting wood. Most of the fungal mass of any forest consists of these mycelia, with actual visible mushrooms only constituting a small fragment of the total fungal mass.
