Algae Flashcards
1
Q
Blue-green bacteria
A
Unicellular
Cyanobacterium
Evolved oxygen generating photosynthesis - created oxygen rich organisms
Nitrogen fixers
2
Q
Dinoflagellates
A
Unicellular Secondary endosymbiosis w red algae Cell walls like armor plates 2 flagella to spin in water Mutualistic relationship with coral Have toxins that stun prey
3
Q
Euglenoids
A
Unicellular
Secondary endosymbiosis with green algae
Unique flagellum
Store polysaccharides instead of starch
4
Q
Diatoms
A
Unicellular Stramenopiles 25% of earths productivity Cell wall 2 halves like Petri dish Extremely strong Animal like life cycle (gametes only haploid) but mostly asexual reproduction Captures sunlight and convert to sugar
5
Q
Golden algae
A
Unicellular/colonial organism closely related to diatoms and brain algae
Pigment impart gold
6
Q
Brown algae
A
Multicellular
Holdfast holds to substrate
Stipe elevates blades is it can reach light
Flexible and durable tissues
7
Q
Red algae
A
Multicellular
Deepest water algae
8
Q
Green algae
A
Multicellular, unicellular, colonial
Simple alternation of generations
