Palisade Mesophyll Cells in a Leaf

What is the main function of a palisade cell?

Major site of photosynthesis

What are some of the features of a palisade cell?

• Has many chloroplasts, used for photosynthesis

• Maximises light absorption

• Cells are tightly packed

• Cytoskeleton moves the chloroplasts around the cell

• Large vacuole

Why does the palisade cell have long narrow gaps?

• Helps the air circulate

• For gas exchange

• For gas diffusion (moving from high to low pressure)

Describe the structure of a palisade cell?

• Cylindrical shape

• Arranged at right angles to the epidermis

• Chloroplasts are near the edge of the cell to absorb more light

• Has a large vacuole

• Has thin and transparent cellulose walls
