Why do dicots have palisade parenchyma on their leaves?
Dicot leaves are generally dorsiventral, having palisade cells on the upper surface of the leaf which receives light, and lower surface has spongy parenchyma for gaseous exchange with several stomatal pores. The palisade cells are columnar with large number of chloroplasts to trap maximum light.
What are the 2 layers that the mesophyll made of?
The mesophyll is located between the upper and lower epidermis.
Why do palisade layers have more chloroplasts?
Mesophyll tissue forms the bulk of the green leaf. It makes up the green tissue of the leaf and consists of thin-walled cells containing chloroplasts (bits that contain the chlorphyll). In most dicot plants, the mesophyll is differentiated into palisade parenchyma and spongy parenchyma. The palisade parenchyma consists of thin-walled cells which are usually cylindrical. These cells contain large numbers of chloroplasts - the organelle used for capturing light and subsequesnt photosysnthesis. The spongy prenchyma, however, contains much lesser chloroplasts, so its main function iot photosynthesis. The spongy parenchyma has an open and net-like structure with large inter-cellular spaces that facilitate gas diffusion. The major function of the spongy parenchyma is the transport of oxygen, carbon-dioxyde and water vapour. It also is involved in the transport of water and the products of photosynthesis, the sugars. The spongy parenchyma is in close connection with the vascular bundles and the palisade parenchyma. When no clear differentiation exists between palisade and spongy parenchyma, the tissue is called mesophyll.
Does a parenchyma have a nucleus?
Parenchyma is the bulk of an organ. Cells have nuclei. Organs comprise tissues, which comprise cells, each of which has a nucleus (RBCs excepted.)
What substances are produced in palisade cells but not xylem cells?
Chloroplasts
What are cells between the upper and lower epidermis of the leaf called?
Mesophyll In between upper and lower epidermis of leaf is mesophyll tissue. In the dorsiventral leaves, mesophyll is divisible into upper palisade cells and lower spongy parenchyma. The palisade cells are mainly involved in photosynthesis and spongy parenchyma in gaseous exchange.
The long narrow cells located directly beneath the upper epidermis are called palisade parenchyma cells?
True
Why do dicots have palisade parenchyma on their leaves?
Dicot leaves are generally dorsiventral, having palisade cells on the upper surface of the leaf which receives light, and lower surface has spongy parenchyma for gaseous exchange with several stomatal pores. The palisade cells are columnar with large number of chloroplasts to trap maximum light.
What two types of tissue cells can make food?
Palisade and spongy parenchyma in the leaves
What is the function of the palisade?
They absorb the light needed for photosynthesis.
What are the 2 layers that the mesophyll made of?
The mesophyll is located between the upper and lower epidermis.
Is the palisade layer where most photosynthesis in a leaf occur?
Mesophyll tissue forms the bulk of the leaf. It makes up the green tissue of the leaf and consists of thin-walled cells containing chloroplasts (bits that contain the chlorphyll). In most dicot plants, the mesophyll is differentiated into palisade parenchyma and spongy parenchyma. The palisade parenchyma consists of thin-walled cells which are usually cylindrical. These cells contain large numbers of chloroplasts - the organelle used for capturing light and subsequesnt photosysnthesis.The spongy prenchyma, however, contains far fewer chloroplasts, so its main function is not photosynthesis. The spongy parenchyma has an open and net-like structure with large inter-cellular spaces that facilitate gas diffusion. The major function of the spongy parenchyma is the transport of oxygen, carbon-dioxyde and water vapour. It also is involved in the transport of water and the products of photosynthesis, the sugars.

What is a parenchyma cell?
A parenchyma cell is the most common type of plant cell. It stores starch, oils, and water for the plant. You can find parenchyma cells throughout a plant. These cells have thin walls and large water-filled vacuoles in the middle. Photosynthesis occurs in green chloroplasts within parenchyma cells in leaves. Both chloroplasts and colorless plastids in parenchyma cells within roots and stems store starch. The flesh of many fruits we eat is also made of parenchyma cells. Parenchyma cells are sometimes thought of as the least specialized of plant cells, but they have one very special trait, the ability to divide throughout their entire lives. Oh, the parenchyma cell, as it says at the top of this answer, "is the most common type of a plant cell..." well, what are the other cells, I'll tell ya', a parenchyma cell is one of three of the basic plant cell types, along with collenchyma and sclerenchyma, you should check them out, as they are cousins in this topic.
what are palisade cells?
Palisade cells are plant cells located on the leaves
The primary function of the palisade mesophyll?
Mesophyll tissue forms the bulk of the leaf. It makes up the green tissue of the leaf and consists of thin-walled cells containing chloroplasts (bits that contain the chlorphyll). In most dicot leaves the mesophyll is differentiated into palisade parenchyma and spongy parenchyma. The palisade parenchyma consists of thin-walled cells which are usually cylindrical. These cells contain large numbers of chloroplasts (used in photosynthis). The spongy mesophyll are usually ball-shaped with large intercellular spaces, but usually contains fewer chloroplasts than the palisade cells. The palisade mesophyll, bundle sheath and spongy mesophyll are known as the ground parenchyma. There is a system of air spaces which communicate with the air chambers behind the stomata (which are like our pores). Since the mesophyll cells contain chloroplasts the tissue is also referred to as chlorenchyma . To sum it up, the functions of the Mesophyll are......... * The palisade cells are responsible for photosynthesis because they contain chloroplasts. * The spongy mesophyll, together with the intercellular air spaces, allow for the interchange of gases.

What cells are in a layer in the top half of the leaf?
The very top of the leaf is covered by a cuticle. Directly underneath this cuticle, and underneath the whole of the upper epidermis, is the layer of chloroplasts, ont he palisade parenchyma layer.
