What else can I help you with?
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 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.
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.
What kind of tissue forms the majority of leaf?
The majority of a leaf is composed of mesophyll tissue, which contains two types: palisade mesophyll and spongy mesophyll. Palisade mesophyll is located near the upper surface of the leaf and is responsible for most of the photosynthesis, while spongy mesophyll is found below and aids in gas exchange and nutrient storage.
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 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.
What do the spongy mesophyll cells do?
Trap plenty of air in the air spaces
Which plant tissue in the leaves has many air spaces?
The spongy layer or mesophyll has many air spaces.
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 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 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 advantage of the presence of air spaces in the mesophyll?
Hydrophytes such as water lilies have lots of air in their spongy mesophyll, this helps the leaves float on the top of the water by increasing the buoyancy of the leaf. In general the air spaces in the spongy mesophyll of a leaf are useful for the circulation of gases, taking in CO2 and releasing O2 as well as the movement of water vapor, due to the process of transpiration.
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 fill the space between spongy mesophyll cells?
The space between spongy mesophyll cells is filled with intercellular air spaces. These air spaces facilitate gas exchange, allowing carbon dioxide to diffuse into the cells for photosynthesis and oxygen to exit. Additionally, the air spaces help maintain moisture within the leaf, contributing to the overall efficiency of the plant's respiratory processes.
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
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.
