F ... 20 - Algae and Bryophytes Flashcards
1
Q
nonvascular plants
A
mosses
liverworts
hornworts
2
Q
vascular plants
A
nonseed plants (ferns) seed plants (conifers, flowering plants)
3
Q
organisms other than plants that conduct photosynthesis
A
cyanobacteria
phytoplankton
photosynthetic algae
4
Q
major groups of algae
A
brown
red
green
5
Q
brown algae
A
chloroplasts contain carotenoid fucoxanthin
6
Q
red algae
A
chloroplasts contain phycobilin
7
Q
algae life cycle
A
sporophyte dominant
8
Q
green algae
A
chlorophyll A and B store starch inside plastids firms cell walls - cellulose - hemicellulose - pectin
9
Q
kingdom plantae general char
A
- contain chlorophyll A and B
- starch within chloroplasts
- cellulose primary component of cell walls
- phragmoplast and cell plate during cell division
- sporic life cycle (alt gen)
- oogamous (sexual reprod)
- embryos
- protective layer of sterile cells around sex cells
10
Q
land plant char lacking from green algae
A
- apical meristem tissues
- 2n sporophyte gen
- male/female forming structures with protective layer
- spores generated in protective layer in sporophyte
- spore wall generated with sporopollenin resists decay
- sporophyte dependence on gametophyte gen
- non flagella egg
11
Q
benefits of living on land
A
plentiful sunlight
abundant CO2
reduced competition, pathogens, herbivores
12
Q
bryophyte char
A
gametophyte dom sporophyte depends on gametophyte no xylem / phloem rhizoids (no roots) flagellate sperm (req water)
13
Q
bryophyte
A
mosses
hornworts
liverworts
14
Q
liverworts
A
unicellular rhizoid
no stomata or specialized conductive tissue
- pores for gas exchange
15
Q
hornworts
A
unicellular rhizoid
stomata, no specialized conductive tissue
