Question

There are three main regions in leaves: the epidermis, mesophyll and veins. Explain the roles each of these play in the proper functioning of a leaf by completing the fo palisade mesNyll guard cells bundle sheath spongy mesophyll mesophyll stomata is a single-celled, mostly non-photosynthetic, protective layer that constitutes the upper and lower surface of leaf blades. The upper layer is The generally covered by a thick, waxy coating of to help minimize water loss. Alternatively, the lower layer contains a number of pores, called for gas exchange. The around these pores are the only cells that contain chlorophyll and can conduct photosynthesis region of the leaf is particularly important for photosynthesis. The upper layer, called the Composed of two distinct layers, the consists is made up of of 1 or 2 rows of packed parenchyma cells that contain over 80% of the leaf s chloroplasts. The lower layer, called the packed parenchyma cells. The regions between these parenchyma cells are called The which are found scattered in the mesophyll, transport materials to and from the leaf. This region is composed of three main areas: the which transports carbohydrates, the which transports water, and the which surrounds and protects the other two structures.
