Rhodophyta - Florideophyceae Flashcards
chloroplast of rhodophyta
in ALL Rhodophyta
- starry + reticulated shape
-one or more pyrenoids possible
pit connections
- present in Rhodophyta -> Florideophyceae
- link the cells, allowing the continuous cells of a filament to communicate
pit plugs
(Florideophyceae)
- protein core + plug-cap + cap membrane
- plug-cap can vary layers: 7 diff. types
(distinguish-merkmal) - thickness/ presence of membrane
(distinguish-merkmal)
secoondary pit-connections
(Florideophyceae)
- prim. pit connections: black parts between cells übereinander (connections of cells of SAME filaments)
- some cells of 1 filament can join with other adjacent filaments = second pit-conn. (DIFFERENT filaments)
consequence: deformation

with main axis and branched - left: connections between diff. filaments
A?
B?
(Florideophyceae)
two types of construction
- A: uniaxial
- B: multiaxial
what type of construction?
(Florideophyceae)
uniaxial
what type of construction?
(Florideophyceae)
multiaxial
(Florideophyceae)
- secondary pit-connections forming a pseudoparenchymatic thallus
- the outer part is called cortex, while the innermost part of the thallus is called medulla
what thallus organization is that?
(Florideophyceae)
- cortical cells: pigmented
- axial cells: not-pigmented, large vacuole
what thallus organization is that?
(Florideophyceae)
what thallus organization is that?
(Florideophyceae)
- one or >1 central filament
- lateral (seitlich) branches
what thallus organization is that?
(Florideophyceae)
foliose and fleshy erect thalli
what thallus organization is that?
(Florideophyceae)
foliose and fleshy erect thalli
