Anatomy. The photosynthetic mesophyll cells are thin walled and radiate from the bundle sheath into the intercellular spaces (Figure 1). ... It contains numerous chloroplasts, is not in contact with the intercellular spaces, and its cell walls are sometimes suberized.

Are chloroplasts found in mesophyll cells?

Mesophyll chloroplasts are randomly distributed along cell walls, whereas bundle sheath chloroplasts are located close to the vascular tissues or mesophyll cells depending on the plant species. ... However, only mesophyll chloroplasts can change their positions in response to environmental stresses.

What does a leaf mesophyll cell contain?

Mesophyll cells in monocotyledonous leaves are often highly lobed. Mesophyll cells originate from the L2 and L3 layers of the shoot apical meristem. A major role of leaf mesophyll cells is to contain large populations of chloroplasts, which carry out photosynthetic carbon assimilation facilitating plant growth.
