Fungal spores. Coloured scanning electron micrograph (SEM) of the spores of an unidentified fungus. These are the reproductive bodies, which vary greatly in structure between species. Their size and shape can often be used to identify the fungus. Fungi are similar to plants in that they possess a cell wall and absorb nutrients in soluble form, but they lack chlorophyll and are therefore unable to photosynthesize. Many grow in the form of microscopic threads known as hyphae, which branch to form a mycelium. Each fungal spore is capable of germinating to produce a new hypha. Magnification: x500 at 6x7cm size.
