Plant cell wall

Question 1

Plant cell wall - structure

Answer 1

contains cellulose held together in microfibrils set in a matrix called pectin

Question 2

Plant cell wall - function

Answer 2

• Transport
  - gaps between cellulose fibres make cell wall fully permeable to water
• Mechanical strength
  - structure/arrangment of cellulose microfibrils make cell wall strong
• Communication between cells
  - plasmodesmata pass between cells allowing for communication
