Prymnesio- / Haptophyta

Question 1

difference in pigments between Ochrophyta and Haptophyta?
other differences?

Answer 1

• fucoxanthin and its derivates
• presence of haptonema and coccoliths in Haptophyta

Question 2

what is that? how can you tell?

Answer 2

• Haptophyta
• unicellular
• 2 smmooth flagella (apical)
• 1 (here: coiled) haptonema
• cell wall covered with scales

Question 3

do haptophytes have 3 flagella?

Answer 3

• 2 flagella
  1. smooth
  2. can have the same length = isokont
  3. can have diff. lengths = heterokont
  4. apically or subapically
• 1 haptonema

Question 4

what is a haptonema?

Answer 4

Question 5

functions of haptonema

Answer 5

Question 6

movement of haptonema

Answer 6

• coiling: when it recognizes obstacles
• bending: for capturing food

Question 7

cell wall of haptophyta

Answer 7

• nude
• covered with several layers of scales

Question 8

what is that?

Answer 8

organic scale of Haptophyta

Question 9

where are scales formed?

Answer 9

• in Golgi bodies
• release is continuous
• scales are continuously renewed (coccoliths fall off)

Question 10

important for characterization of Coccolithophycean?

Answer 10

1. shape of scale
2. coccosphere (arrangement of structure)

Question 11

what’s the functions of coccoliths?

Answer 11

Question 12

what is a coccosphere?

Answer 12

the arrangement of a coccolith to form a structure

Question 13

how can the coccosphere be divided?

Answer 13

Question 14

what is that?

Answer 14

dimorphic Coccolithophycean

Question 15

Answer 15

dimorphic Coccolithophycean

Question 16

Answer 16

dimorphic Coccolithophycean
or dithecate

Question 17

Answer 17

maybe dithecate Coccolithophycean? ( 2 layers of diff. coccoliths)

Question 18

what are these?

Answer 18

• different species of Coccolithophyceans
• specific features
