Where does most of the photosynthetic activity of a leaf take place?
In the spongy and palisade mesophyll, due to the large amounts of chloroplasts.
Why do you think the palisade mesophyll cells are columnar in shape?
They containchloroplasts, which convert the energy in light to chemical energy throughphotosynthesis. The cylindrical shape of palisade cells allows a large amount of light to be absorbed by the chloroplasts. Beneath the palisade are the spongy mesophyll cells, irregularly-shaped cells that having many unicellular spaces to allow the passage of gases, such as the intake of carbon dioxide for photosynthesis to take place.
Photosynthesis is carried out in these which are located in the cellthat are underneath the epidermis?
The palisade mesophyll is located directly beneath, and then the spongy mesophyll is located beneath that. Both contain large amounts of chloroplasts which carry out photosynthesis.
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.
Is an Elephant large because it has large cells?
No, an elephant is not large because it has large cells.
What are the adaptations of spongy mesophyll cells?
Spongy mesophyll cells are usually ball or irregularly shaped and contain a limited number o chloroplasts. It is found below the palisade layer. The large spaced between each cell in the mesophyll allow for the exchange of gases which is incredibly important to a plants survival. It is how the carbon dioxide is received and the oxygen is released.
What does the spongy layer of a privet leaf do?
Spongy Layer - A layer of the mesophyll. The spongy layer consists of chloroplasts and parenchyma cells, and relatively large intercellular spaces. It is far less ordered than the palisade layer, and the intercellular spaces are important in gas exchange and transpiration.
Where does most of the photosynthetic activity of a leaf take place?
In the spongy and palisade mesophyll, due to the large amounts of chloroplasts.
What is the job of the spongy mesophyll layer?
spongy mesophyll is the air spaces in a plant that allow air to diffuse among the cells which are producing and releasing both CO2 and O2. Thus the answer is the area where gas exchange occurs
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.

Difference of spongy to palisade layer?
Because it contains air spaces which help regulate gas exchange in leaves and because most of the chloroplast are located in the palisade layer, it is here where the photosynthesis mainly takes place.
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.

Cells that are specialized for photosynthesis?
The leaf is specialized for photosynthesis because the millions of tiny chloroplasts are spread out along a large flat surface. this works kind of like a solar panel. the bigger the leaf, the more sun it absorbs.
What is the function of Spongy tissue?
Spongy Layer - A layer of the mesophyll. The spongy layer consists of chloroplasts and parenchyma cells, and relatively large intercellular spaces. It is far less ordered than the palisade layer, and the intercellular spaces are important in gas exchange and transpiration.
What is the palisade mesophyll?
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
