Q

pit connections

A

present in Rhodophyta -> Florideophyceae
link the cells, allowing the continuous cells of a filament to communicate

Q

pit plugs

A

(Florideophyceae)
- protein core + plug-cap + cap membrane

plug-cap can vary layers: 7 diff. types
(distinguish-merkmal)
thickness/ presence of membrane
(distinguish-merkmal)

Q

secoondary pit-connections

A

(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

Q

A

(Florideophyceae)
- secondary pit-connections forming a pseudoparenchymatic thallus
- the outer part is called cortex, while the innermost part of the thallus is called medulla
