Dinoflagellata - Miozoa Flashcards
Dinoflagellata
pigments, storage products, cell wall, flagella
what type of Dinoflagellate?
Desmokont
what type of Dinoflagellate?
Dinokont
what is that?
transverse flagellum in Dinokonts
which flagella girls cell? what about the hair?
- transverse flagella
- single row of hairs, lateral
do Dinoflagellates have eyespots?
yes
- extraplastid in cytoplasma
- chlorplastic within chloroplast
what’s that structure?
- pusules
- organelle
- invaginations of plasmalemma
- osmoregulation
what’s that? what for? where?
- trichocyst = protein structure
- on cell surface
- can discharge for rapid movement to escape
unusual features in Dinoflagellata
name of cell wall in Dinoflagellates
- they have no cell wall
- but beneath plasmalemma: theca
if 2 large plates are at the apical end of a Dinoflagellate, then it is a ?
Desmokont
what’s that? how do I know?
- Desmokont
- 2 large plates are at the apical end
- 2 flagella at apical end
what’s that? how do I know?
- Desmokont
- 2 large plates are at the apical end
- 2 flagella at apical end
how can Theca be in Dinokonts?
left? right?
describe
what’s that?
- thecal plates
- separated by ribs
- perforated by pores
- connected by intercalary bands
describe the different components.
what type?
what’s that?
- dinokont
- left: ventral view
- right: dorsal view
dinokonts
- easy to identify
1. high number of pores
2. 2 horns
dinokont
dinokont with presence of several horns
dinokont with presence of several horns
what is that? why important
- tabulation
- diff. arrangements of thecal plates
important for taxonomy and differentiation
