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 else can I help you with?
What part of the leaf has air spaces to facilitate the diffusion of gases?
The region in the leaf that has air spaces to facilitate the movement of gasses is the mesophyll region. This region is composed of layers of cells.
Are spongy mesophyll in leaf?
yes :)
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 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.
How many layers does the mesophyll have?
The mesophyll has two layers. The outermost layer is the palisade layer that is made of tightly packed chloroplasts, and the innermost layer is the "spongy layer" that has air between its cells.
What are types of mesophyll cells?
The two main types of mesophyll cells found in plant leaves are palisade mesophyll cells and spongy mesophyll cells. Palisade mesophyll cells are located in the upper layer of the leaf and are specialized for photosynthesis, while spongy mesophyll cells are found beneath the palisade layer and aid in gas exchange and the storage of nutrients.
True or false spongy mesophyll are cells in a leaf?
True. Spongy mesophyll cells are found in the leaf tissue of plants and are involved in the exchange of gases necessary for photosynthesis.
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 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.
Does photosynthesis take place in spongy mesophyll cells?
yes
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 are the 2 layers that the mesophyll made of?
The mesophyll is located between the upper and lower epidermis.
