I had to find the answer to the question too. I think it is to allow gases to diffuse around the cells.
It is too important for the gases oxygen when respiring and carbon dioxide when photosynthesis and water during transpiration
What else can I help you with?
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 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 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 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.
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 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.
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.
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.
Does photosynthesis take place in spongy mesophyll cells?
yes
What are the advantages of having no chloroplast in the spongy mesophyll cells?
What would be the advantages to having no chloroplasts in the cells of the spongy mesophyll? Fewer chloroplasts in the spongy mesophyll because most of the light energy is absorbed by the chloroplasts of the palisade mesophyll. ... They waxy cuticle keeps water inside the leaf cells.
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.
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.
