what is the function of a palisade mesophyll cell?

Answer 1

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 .

So sweetie, 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.

Palisade cells are cells found within the mesophyll in leaves of dicotyledonous plants. They contain chloroplasts, which convert the energy stored in photons to chemical energy through photosynthesis, which is made up of two main stages; thelight-dependent reactions and light-independent reactions. The cylindrical shape of palisade cells allows a large amount of light to be absorbed by the chloroplasts. Beneath the palisade mesophyll are the spongy mesophyll cells, irregularly-shaped cells that having many intercellular spaces to allow the passage of gases, such as the intake of carbon dioxide for photosynthesis to take place. The stomata is the way in which these gases are exchanged, as well as the transpiration of water from the xylem, either by the apoplast or symplast pathway. Palisade cells are positioned towards the upper surface of the leaf and contain the largest number of chloroplasts per cell in plants. This makes them the primary site of photosynthesis in a plant's leaves. They have a very large surface area in order for them to absorb more light during photosynthesis...!!

Answer 7

"Palisade cells is type of mesophyll (plant tissue) and can be found inside the leaf of a green plants. They contain chloroplasts that absorb sunlight to convert the energy in photons to chemical energy through photosynthesis.

Palisade cells take a cylindrical shape in order to allow as much light to pass through and be absorbed as possible. These cells produce carbohydrates in photosynthesis faster than they use them.

They contain the most amount of choroplasts than any other cell in the plant and the chloroplasts are usually postioned at the top of the leaf in order to catch the most amount of sunlight." directly cut from wikipedia

Mesophyll Function

Answer 9

The mesophyll, sandwiched between the upper and lower epidermis, consists of many thin-walled cells that are usually arranged in two layers. The palisade layer is next to the upper epidermis. It consists of cylindrical cells that are packed closely together. Next to the palisade layer and making up most of the thickness of the leaf blade is the spongy layer. The spongy layer consists of roundish cells that are packed loosely together and have numerous air spaces between them. In most plants the spongy layer extends down to the lower epidermis. However, in certain grasses, irises, and other plants whose leaves grow straight up and down, the spongy layer is wedged between two palisade layers of mesophyll. Like the guard cells, all the cells of the mesophyll contain chloroplasts.

Answer 10

Palisade mesophyll is a tissue in leaves. The cells contain chloroplasts needed for photosynthesis, especially the light dependent reactions. This makes sense considering that it is just below the transparent upper epidermis and this makes it easy for the reactions to take place
