Algae are a group of photosynthetic plants.
Most are aquatic.
They have a basic structure called a thallus, i.e. the plant body is not divided into roots, stem and leaves.
Within the group there is a great variety of size and structure from the single-celled Chlamydomonas to the giant seaweeds.
We will look at three examples of algae:
(a) The unicellular type - Chlamydomonas.
(b) The filamentous type - Spirogyra.
(c) The brown seaweed - Fucus vesiculosis.
