| Is the lichen question part of your homework? If so, you really should be reading your material and finding the answers. Not being mean, but you will remember the things you search out yourself and will not remember the answers you are given. Anyway, a lichen is essentially a fungus that contains algae in its tissues. Fungus can't photosynthesize, algae can, so the fungal cells get food from the algae and the algae cells get water and minerals from the fungus. |
