Where is the spongy mesophyll located?

Where is the spongy mesophyll located?

The spongy mesophyll layer is located directly below the palisade mesophyll layer. It consists of irregularly-shaped cells that are loosely packed with air spaces in between.

What is the structure and function of the spongy mesophyll?

What is the function of the spongy mesophyll in a leaf? The spongy mesophyll contains irregularly shaped cells with wide gaps between them in order to facilitate carbon dioxide diffusion and gas exchange via the stomata. Spongy mesophyll also contains chloroplasts responsible for photosynthesis.

What is the function of the mesophyll?

The most important role of the mesophyll cells is in photosynthesis. Mesophyll cells are large spaces within the leaf that allow carbon dioxide to move freely.

What are the spongy mesophyll?

spongy mesophyll In a leaf, mesophyll tissue comprising cells of irregular shape, some of them lobed, separated by large spaces in which the atmosphere is humid. Spongy mesophyll is the site of gaseous exchange for photosynthesis and respiration.

What is spongy mesophyll made of?

The spongy mesophyll contains calcium oxalate, mainly in the form of single and twin prisms, but clusters and microsphenoidal crystals are also present (Fig.

What is palisade and spongy mesophyll?

In dicotyledonous leaves there are two types of mesophyll cell; palisade mesophyll and spongy mesophyll. Palisade mesophyll cells are elongate and form a layer beneath the upper epidermis, whereas spongy mesophyll cells are internal to the lower epidermis.

What is the difference between spongy mesophyll and palisade mesophyll?

Why does spongy mesophyll have air spaces?

Intercellular air spaces within the spongy mesophyll layer – they allow the diffusion of carbon dioxide and oxygen. Stomata (small pores usually found on the lower surface of the leaf) – allow carbon dioxide and oxygen to enter and leave the leaf.

What is the function of the spongy layer in a leaf?

Spongy layer Although they contain a few chloroplasts, their main function seems to be the temporary storage of sugars and amino acids synthesized in the palisade layer. They also aid in the exchange of gases between the leaf and the environment.

What is the function of the palisade and spongy layers?

The cuticle and upper epidermis provide protection for the plant. Below that is the palisade layer, which is the location of photosynthesis within the leaf. Below the palisade layer is the spongy layer, which contains cells that are more spread out, allowing for air pockets.

What does palisade and spongy mesophyll do?

Spongy mesophyll and palisade mesophyll are types of cells involved in the the processes leading up to photosynthesis as well as photosynthesis itself and are located in the leaves of vascular plants.

What is the difference between palisade and spongy mesophyll?

What is the function of mesophyll tissues in leaf?

mesophyll Internal parenchyma tissue of a plant leaf that lies between epidermal layers. Its main functions are photosynthesis and the storage of starch.
