Document Summary

Lecture notes 1- introduction and diversity of algae: terrestrial environment can have as much as 1,000 times more autotrophic (plant) biomass than marine environments. However, terrestrial and marine ecosystems contribute almost equally to the annual photosynthesis on earth. Where: algae are mostly found in aquatic environments but some can be found in terrestrial environments. Mixotrophy is a combination of autotrophy and heterotrophy, depending on the availability of resources: describe the different morphological types in algae, there is unicells, which are solitary cells and can be nonmotile or motile. There are colonies that are an assemblage of a variable number of individual cells that can also be motile or nonmotile. There are filaments, which are a common type of algal body where the cells adjacent share a common cell wall. Coenocytic or siphonaceous forms are less common but they consist of one large multinucleate cell without cell walls. Cellular bisection consists of longitudinal or transverse cell division.
