Where is the spongy layer located?
The spongy layer is located beneath the upper epidermis in the mesophyll tissue of plant leaves. It is made up of loosely packed cells with air spaces between them, allowing for gas exchange and photosynthesis to occur more efficiently.
Why are cells of the spongy layer packed so loosely together?
All plant cells respire all of the time and need to exchange gases. The main gas exchange surface in plants are the spongy mesophyll cells in the leaves. Leaves have a huge surface area, and the irregular-shaped, loosely-packed spongy cells increase the area for gas exchange even more.
How does the structure of the spongy tissue differ from that of other leaf tissues?
Spongy tissue in leaves has loosely packed cells with large air spaces between them, facilitating gas exchange. In contrast, other leaf tissues like palisade mesophyll have tightly packed cells arranged in columns for efficient photosynthesis. Spongy tissue is located beneath the palisade layer and aids in maximizing gas diffusion within the leaf.
What 3 kinds of leaf cells contain chloroplasts?
Palisade cells, spongy mesophyll cells, and guard cells contain chloroplasts in leaves. Palisade cells are located in the upper leaf epidermis, spongy mesophyll cells are below the palisade layer, and guard cells surround the stomata.
What is a leaf layer that contains air spaces?
Leaves consist mostly of tissue called mesophyll, which is made up of loosely arranged cells with spaces between them. The spaces are filled with air, from which the cells absorb carbon dioxide and into which they expel oxygen.
The lower portion of the mesophyll usually consisting of loosely packed spherical cells?
spongy layer
What is beneath the palisade layer of a leaf?
Beneath the palisade layer of a leaf is the spongy mesophyll layer. This layer contains loosely packed cells with air spaces between them that allow for gas exchange, such as the intake of carbon dioxide and the release of oxygen during photosynthesis.
Where is the spongy layer located?
The spongy layer is located beneath the upper epidermis in the mesophyll tissue of plant leaves. It is made up of loosely packed cells with air spaces between them, allowing for gas exchange and photosynthesis to occur more efficiently.
What Is the dfference between paliside and spongy?
The palisade layer of cells is tightly packed, like a brick wall, and contains the greatest concentration of chloroplasts in the leaf. The spongy mesophyll is loosely packed, containing many air spaces between the cells. The mesophyll contains vascular bundles and fewer chloroplasts than the palisade. Simply put, the palisade's main purpose is photosynthesis, and the spongy's gas exchange.
What are two types of mesophyll?
The two types of mesophyll in plant leaves are palisade mesophyll and spongy mesophyll. Palisade mesophyll is located closer to the upper epidermis and consists of closely packed cylindrical cells that are specialized for photosynthesis. Spongy mesophyll is located beneath the palisade layer and consists of loosely arranged cells with air spaces for gas exchange and moisture retention.
Why are cells of the spongy layer packed so loosely together?
All plant cells respire all of the time and need to exchange gases. The main gas exchange surface in plants are the spongy mesophyll cells in the leaves. Leaves have a huge surface area, and the irregular-shaped, loosely-packed spongy cells increase the area for gas exchange even more.
Why do leaves have spongy tissue?
Leaves have spongy tissue to facilitate gas exchange and photosynthesis. This tissue, located in the mesophyll layer, contains loosely arranged cells with air spaces that allow carbon dioxide to diffuse into the leaf and oxygen to exit. Additionally, the spongy tissue helps in retaining moisture and provides structural support, ensuring the leaf can efficiently capture light and perform its vital functions.

What is a layer of cells that lies below the palisade layer and has many air spaces?
Spongy 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.
