Distinguishing between the green algae

Question 1

Green algae have which types of chlorophyll

Answer 1

a + b

Question 2

green algae store their photosynthate as

Answer 2

starch

Question 3

what type of -troph are green algae

Answer 3

most are obligate photoautotrophs

Question 4

What was the primitive green alga

Answer 4

prasinophyceans

• they are scaly, asymmetric, and multiflagellated with ejectiles

Question 5

Describe the flagella of prasinophyceans

Answer 5

• these are primitive green algae
• they have asymmetric multi-flagellated
• their flagella are firmly attached and don’t get easily lost

Question 6

what type of cell division did the prasinophyceans do

Answer 6

• these are the primitive green algae
• they do furrowing cell division

Question 7

What does open mitosis mean

Answer 7

a form of cell division where the entire nucleus membrane dissolves

Question 8

What does closed mitosis mean

Answer 8

this is a form of cell division where the nuclear membrane stays in place

Question 9

what does metacentric mean

Answer 9

this is a form of cell division where the nucleotides holding the spindles go to the equatorial side

Question 10

Describe furrowing

Answer 10

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

Question 11

describe the phragmoplast

Answer 11

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

Question 12

describe phycoplast

Answer 12

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

Question 13

Describe the 3 parts of the flagellar apparatus in green algae

Answer 13

flagella + basal bodies + flagellar roots

Question 14

Chlorophycean have what kinds of flagellar apparatus

Answer 14

• clockwise cruciate arrangement
• direct cruciate arrangement

Question 15

Ulvophycean have what kind of flagellar apparatus

Answer 15

counter clockwise cruciate arrangement

Question 16

Charophycean have what kind of flagellar apparatus

Answer 16

asymmetric arrangement with MLS

Question 17

Characterize the flagellar roots of the green algae

Answer 17

• MLS characterizes the 2 flagellar roots of the charophycean
• 4 flagellar roots and cruciate characterize the others

Question 18

What are the 3 green algal groups

Answer 18

1. Chlorophyceae
2. Ulvophyceae
3. Charophyceae
