Transverse binary fission
Asexual
Where are diatoms found?
Oceans and lakes.
Unicellular algae that are a large component of phytoplankton
What lifestyle do cercozoans demonstrate?
Predators, and parasites found in freshwater, marine, and soil ecosystems

1. Proteobacteria
2. Chlamydias
3. Spirochetes
4. Cyanobacteria
5. Gram-positive bacteria
Where are euglenids found?
Freshwater especially when its rich in organic materials with a few marine and endosymbiotic members
What are the general characteristics of the Clade dinoflagellates
Reinforced cellular plates with two flagella, one apical and one in a groove within the plates
What are the general characteristics of the clade Phaeophyta?
Get their color from the brown or olive color (pigments: carotene and fucoxanthin) in their plastids
Evolved a gel-like substance called algin
What are the general characteristics for the clade cercozoans?
Amoebid shaped protista with thin pseudopodia

Two haploid nuclei
What lifestyles do ciliates demonstrate?
Ectosymbiotic and endosymbiotic members as well as some obligate and opportunistic parasites
What lifestyles do oomycetes demonstrate and why?
Lost their plastids and are therefore either decomposers or parasites
What are the tests of foraminiferans made of and what are they symbiotic with and what do they provide them?
Photosynthetic algae that can live in their calcium carbonate test and provide them with nourishment
