What is the advantage of the spongy mesophyll being loosely arranged instead of being closed?
in between the spongy mesophyll cells, there are air spaces. this allows faster diffusion of CO2 into the leaf. the thin film of moisture on the spongy mesophyll evaporates in the air spaces in the process of transpiration, thus helped in transpiration pull. without the spongy mesophyll being loosely arranged, there would not be air spaces.

What is the function of spongey mesophyll in a leaf?
The spongy mesophyll in a leaf functions in gas exchange and photosynthesis. Its loosely packed cells allow for the diffusion of gases, such as carbon dioxide and oxygen, into and out of the leaf. Additionally, it contains chloroplasts that aid in photosynthesis by capturing light energy and converting it into sugars.
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 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.
What is a term describing a loosely knit association of cells?
A multicellular organism.
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.
Why does the middle of the leaf (the spongy region) have loosely arranged cells?
The spaces between the spongy mesophyll cells permit gases to move around within the leaf. That is why they are loosely arranged.
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.
What part of leaves contain more organelles?
The part of leaves that contains more organelles, particularly chloroplasts, is the mesophyll tissue. This tissue is located between the upper and lower epidermis and is primarily responsible for photosynthesis. Within the mesophyll, the palisade mesophyll cells are densely packed with chloroplasts, maximizing light absorption for photosynthesis. In contrast, the spongy mesophyll has fewer chloroplasts and is more loosely arranged to facilitate gas exchange.
How are the two types of mesophyll found in a leaf specialized for photosynthesis?
The two types of photosynthetic mesophyll are -- (i) Palisade cells which are vertically elongated cylindrical cells and (ii) Spongy mesophyll cells that are spherical green cells.
The lower portion of the mesophyll usually consisting of loosely packed spherical cells?
spongy layer
What gives the spongy mesophyll its name?
The spongy mesophyll gets its name due to its porous structure, which resembles a sponge. This layer of tissue, found in the leaves of plants, contains air spaces that facilitate gas exchange, allowing carbon dioxide to diffuse in and oxygen to diffuse out during photosynthesis. The spongy mesophyll's loosely arranged cells maximize the surface area for gas exchange while still providing some structural support to the leaf.
What are the loosely packed photosynthesis cells in the leaf called?
The loosely packed photosynthesis cells in a leaf are called mesophyll cells. These cells are primarily located between the upper and lower epidermis and are rich in chloroplasts, which enable them to efficiently capture sunlight for photosynthesis. The arrangement of mesophyll cells allows for gas exchange and maximizes light absorption.
What are the loosely packed photosynthetic cells in the leaf called?
Thylakoids. Stacks of these are called granna.
How are the cell of a bread mold arranged?
The cells of bread mold are loosely arranged. This is the opposite of the cells of mushrooms which are packed tightly together.
How atomes arranged in a liquid?
the atoms in a liquid are loosely packed together. they can move, but they have to move together.
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.
What is the spongy layer in a plant used for?
The spongy layer, found in the mesophyll of plant leaves, is primarily used for gas exchange and photosynthesis. Its loosely arranged cells create air spaces that facilitate the diffusion of carbon dioxide into the leaf and the release of oxygen. This structure also helps to retain moisture and supports the overall efficiency of photosynthesis by maximizing light absorption.
