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

Where are the palisade mesophyll cells located?
The palisade mesophyll organ belongs to the leaf organ.
What does the palisade mesophyll do in a leaf?
The palisade mesophyll is superior to the spongy mesophyll (in most leaves) which aids in photosynthesis, but also serves a "sun block" to the more sensitive cells the spongy mesophyll.
What does the palisade do in the leaf?
The palisade mesophyll is superior to the spongy mesophyll (in most leaves) which aids in photosynthesis, but also serves a "sun block" to the more sensitive cells the spongy mesophyll.
What is the funtion of palisade mesophyll?
Palisade mesophyll cells are tall and closely packed to absorb maximum light. They contain many chloroplasts. Most photosynthesis takes place in the palisade cells. Spongy mesophyll also captures light and makes food.
What is the column like cells that lie under the epidemis?
Palisade cells are the column like cells that lie just under the epidermis. Palisade layer is one layer of the mesophyll.
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.
Which mesophyll layer is near to the upper epidermis?
Palisade Layer
What is spongy mesophyll layer?
Spongy mesophyll cells are not packed so tightly together, which allows carbon dioxide and oxygen to reach the palisade cells where they are needed in photosynthesis. Spongy mesophyll cells and guard cells (see below) also get some photosynthetic action.
Where is gluconse made in plants?
glucose is made in the "palisade mesophyll cells". glucose is made by photosynthesis which takes place in chloroplasts. chloroplasts are only found in palisade mesophyll cells. hope this helps
What layer in a leaf contains the most chloroplasts?
The leaf layer containin chloroplasts is teh Spongy Mesophyll
Which type of plant cell is rich in chloroplast?
palisade mesophyll cells
What are the 2 layers that the mesophyll made of?
The mesophyll is located between the upper and lower epidermis.
