BIOL 2010 Quiz: Multicellular Protist Groups
Document Summary
Heterotrophs [ slime molds and oomycete: presence of a phycoplast differentiates the chlorophycea, ulvophycea is mostly marine. Bacteria would aggregate at the spectrum that has the most oxygen evolution (experiment). Another group is the volvox - example where we get to see the multicellular structure appearing. Star with single cells like the chlamydomonas and the multi cellular forms such as the volvox. Euglena is an excellent example of a heterotroph: a phylogenetic clade that shows the similarity between them. Heterotrophs: major groups are slime molds and oomycete, within the heterotrophic divisions you have three groups that are still held together known as oomycota, dictyosteliomycota and myromycota. The things that differentiate the three are the cell wall composition and the flagella structures. Oomycota have the heterekont structure: known as oomycete because it has egg cells associated with it. The oogonium have egg cells present within it.
