Archaeaplastida Flashcards
secondary endosymbiosis
supplied most other photosynthetic eukaryotes with their chloroplasts by engulfing Red or green algeae
Multicellular archaeplastida
all cells from single cell
genetically equivalent
cells need eachother to survive
specialization
EX brown algea
Colonial
cells may be genetically distinct
may attach in colonial filaments, can survive alone
EX Volvox - balls in balls
Red/Green algae
independent evolution of multicellularity
some colonial (Volvox)
Ulva- multicellular green
Red algae
marine multicellular
red psynth pigment- absorbs blue
therefore it grows deeper
“coralline” have calcium carbonate and build reefs
funky alternation of generations
Green Algae
most aquatic
symbionts with fungi-> lichen
2 groups
Charophytes general
more closely related to land plants
haplontic
freshwater
Chlorophytes
unicellular, colonial, multicellular
diverse life cycles
First plants
475 mya
Charophyte traits with land plants
unique cellulose synthesis for cell wall
phragmoplast forms in cell div
