wall
Function of vacuole
Maintains strength and structure of the plant cell through hydrostatic pressure
Function of cell wall
Strength, structre and protection

Vacuole membrane
Function of amyloplast
Vesicles to store starch
Function of chloroplast
Convert light energy into carbohydrates
Where is the middle lamella
In between cell walls
What is in the middle lamella
Pectin
What is pectin
Cement like substance that glues plant cells together
What are the plasmodesmata
Channels joining the cystoplasms between connected adjacent cells
What are pits
Underdeveloped plasmodesmata that can develop if required
What type of glucose is starch made from
Alpha
What type of glucose is cellulose made from
Beta
What is the difference in alpha glucose to beta glucose
On C1
Alpha has H at the top OH at the bottom
This is inverted in beta
