  • What are the stomata?
    Cells that close to control water loss
    Pores in the lower epidermis of the leaf

    Lower epidermis
    Stomata
    Palisade layer
  • The leaf tissue that contains the most chloroplasts is...
    The upper epidermis
    The palisade layer
    The guard cells
    The spongy mesophyll layer
  • The function of the thick waxy cuticle is...
    To prevent sunlight from entering the leaf
    To deter predators from eating the leaf
    For photosynthesis
    To stop too much water evaporating from the leaf
  • There are lots of chloroplasts in the palisade mesophyll layer because...
    This is where the majority of photosynthesis occurs
    This provides structure and support to the leaf
    This is where gases diffuse
    This allows storage of cell sap
  • The spongy mesophyll layer is designed for gas diffusion because...
    It has a small surface area and no air spaces
    It has a large surface area and lots of air spaces
    It takes up a lot of space in the leaf
