- Scenedesmus
is an example of a coenobium, or a colony where the shape and
number of cells are determined genetically
in early development and do not change during the life of the
organism. Each parent cell can reproduce
asexually to form nonflagellate cells that align laterally and
develop
- into a daughter colony identical to the parent
colony. The new autocolonies remain curled tightly
- within the parental cell walls until they
are eventually released through a break in the cell wall.
-
- This asexual reproduction is similar to that
of Hydrodictyon and Pediastrum, although the zoospores
of Scenedesmus are not flagellated. Molecular
sequence analyses support this relationship.
