Junctions - Coggle Diagram
Junctions
Plasmodesmata
Desmotubule
Connects ER of two cells
Includes pm tubule and cell wall
Dynamic
Large opening between plant cells
Two types of substances
Appoplast
Between pm and cell wall
Symplast
In plasma membrane
Gap junctions
Communicating junctions which form tiny channels
Dynamic and can prevent infection from spreading
Bacteria cannot move through
Formed by a connexon
Six identical connexions
Tight junctions
Not very strong
Little break in a tight junction can cause total unraveling
Made up of Occludin and claudin
Targeted by pesticides
Anchoring junctions
Adherens junctions
Actin cytoskeleton
Desmosomes
Cell to cell adhesion and Cadherin
Intermediate filaments cytoskeleton
Hemi desmosomes
Intermediate filaments cytoskeleton
Focal adhesions
Cell to extracellular matrix and integrin
Actin cytoskeleton
