Describe the various morphological forms of algae. Give an example and make diagram of
each form.
The term "morphology" describes the shape, form or growth habit of an organism and its parts. Algae exhibit extremely diverse morphology. Some, like Chlorella, are unicellular organisms similar to bacteria, whereas others such as kelp are complex, multicellular organisms with cells similar to plants. Other algae run the gamut of morphological diversity, but can be categorized into several major groups.
Unicellular
· Unicellular algae consist of a single cell. The single cell of the body contains a chloroplast, which conducts photosynthesis to create energy from sunlight, and often contains a structure called a pyrenoid that can store energy and contractile vacuoles that help to regulate the amount of water and salts within the cell (i.e., osmoregulation). Some unicellular algae such as Chlamydomonas are motile, or able to move, using flagella.
