Cell wall and plasmodesmata Flashcards
1
Q
What is the cell wall made up of?
A
Cellulose microfibrils embedded in a polysaccharide matrix called pectin
2
Q
What does the cell wall confer?
A
Rigidity (strength) on plant cells
3
Q
What are the functions are the cell wall?
A
Provides strength and support
Prevents cell from bursting
Control the movement of water from cell to cell
4
Q
What is plasmodesmata?
A
Narrow pores contained within the cell wall
Fine stands of cytoplasm pass through these
Connects one cell to the next
Allows substances to move between them
5
Q
How are the plasmodesmata formed?
A
Formed when the cell wall is interrupted at intervals by narrow pores
Crrying fine strands of cytoplasm which join the living cells to one another
