Plant Cell Organisation

• What is the function of epidermal tissue in plants?

  Reduces water loss
• Why are the cells in the upper layer of epidermal tissue transparent?

  To let light through for photosynthesis
• Where does most photosynthesis occur in a plant?

  Palissade mesophyll
• What is the role of chloroplasts in palissade mesophyll?

  They facilitate photosynthesis
• What is the function of spongy mesophyll tissue?

  Allows diffusion of gases
• Where is meristem tissue found in plants?

  At the growing tips of shoots and roots
• What can meristem cells differentiate into?

  Many types of cells for plant growth
• What is the function of phloem in plants?

  Moves food substances
• How do phloem cells facilitate the movement of cell sap?

  Small pores in end walls
• What is translocation in plants?

  Process of moving food through phloem
• What type of cells make up xylem tissue?

  Dead cells
• What is the primary function of xylem tissue?

  Carries water and mineral ions
• What is the transpiration stream in plants?

  Movement of water through xylem
