CHLOROPHYTA Flashcards
1
Q
General facts of Chlorophyta
A
The green algea
- > CH a & b ; carotenoids
- > Cellulous
- > chloroplasts are primary capture (2 membranes)
2
Q
order Chlamydomonas
A
- > fresh water
- > Gambesets isogamous (look like beetles)
- > zygote only diploid stage produces mieospores
- > zygote is the resting stage of this one
3
Q
order Volvox
A
- > beachball one
- > Asextslly, daughter cells (colonies, clones, mitosis) inside the fall have to flip flagellated tails outward and escape
- > sexually, caused by ENV stress
- > heterogonous gametophyte and sporophyte (zygote)
- > gametes Oogamous (egg and sperm, aogamous)
4
Q
Order Chlorococcales
A
Non-flagellated, unicellular, colonies
5
Q
Class Ulvophyceae
A
mostly marine algae
-> more closely related to land plants
6
Q
Ulva
A
sea lettus, in sheets, multicellular
- > mostly haploid, isomorphic, isogamous gambetes
- > zygotes are quadra-flagilated
- > gambets can grow into a sporophyte asextualy
7
Q
Codium
A
calcified, finger algea
- > on fingers the gametangia is found that produces egg and sperm (asogamous, m smaller)
- > heteromorphic
8
Q
Chara Collina
A
the one that is closely related to land plants
- > there is a jacket over the egg that protects it
- > sperm falls on this egg and cycle continues
9
Q
Spirogyra
A
cork skrew algae that reproduce via conjugations (fillimentous)
