Green algae
Three subgroups of Archaeplastida
Red algae, green algae, land plants
(Algae) Accessory pigment is phycoerythrin
Red algae
(Algae) Color varies from greenish-red in shallow water to dark red-black in deep water
Red algae
Subgroup of algae-> most live in fresh water, although many are marine
Green algae-> chlorophytes
Subgroup of algae-> live in damp soil, as symbionts in lichens, or in environments exposed to intense visible and ultraviolet radiationq
Green algae-> chlorophytes
Ulva

Once thought to be fungi
slime molds
Two lineages of slime molds
Plasmodial and cellular
Describe the division and feeding of the multicellular plasmodium
Undivided by plasma membranes, contains many diploid nuclei, extends pseudopodia to eat by phagocytosis

How has global warming harmed the growth of photosynthetic protists and phytoplankton?
Warm water prevents the upwelling needed to bring nutrients from the ocean floor
