Distinguishing between the green algae Flashcards
Green algae have which types of chlorophyll
a + b
green algae store their photosynthate as
starch
what type of -troph are green algae
most are obligate photoautotrophs
What was the primitive green alga
prasinophyceans
- they are scaly, asymmetric, and multiflagellated with ejectiles
Describe the flagella of prasinophyceans
- these are primitive green algae
- they have asymmetric multi-flagellated
- their flagella are firmly attached and don’t get easily lost
what type of cell division did the prasinophyceans do
- these are the primitive green algae
- they do furrowing cell division
What does open mitosis mean
a form of cell division where the entire nucleus membrane dissolves
What does closed mitosis mean
this is a form of cell division where the nuclear membrane stays in place
what does metacentric mean
this is a form of cell division where the nucleotides holding the spindles go to the equatorial side
Describe furrowing
this is a form of cell division where a new cross wall is formed by pinching off the lateral walls that come together and form a cross wall
describe the phragmoplast
a type of cell division where vesicles start to coalesce and line to form a cross wall –> you get pores through which the cell can communicate
describe phycoplast
a form of cell division where there are no vesicles forming, the spindles turn into microfibers and pull the lateral walls to form a cross wall
Describe the 3 parts of the flagellar apparatus in green algae
flagella + basal bodies + flagellar roots
Chlorophycean have what kinds of flagellar apparatus
- clockwise cruciate arrangement
- direct cruciate arrangement
Ulvophycean have what kind of flagellar apparatus
counter clockwise cruciate arrangement
