What else can I help you with?
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 do leaves let carbon dioxide get to their cells?
Leaves allow carbon dioxide to reach their cells through tiny openings called stomata, which are primarily located on the underside of the leaf. When the stomata open, carbon dioxide enters the leaf and diffuses through the intercellular spaces to reach the photosynthetic cells, primarily chloroplasts. This process is facilitated by the concentration gradient of carbon dioxide, allowing it to move from an area of higher concentration outside the leaf to a lower concentration inside. Additionally, the leaf's internal structure, including air spaces and the arrangement of cells, aids in the efficient transport of gases.
Which layer has the largest cells in elodea leaf?
The lower epidermis of the elodea leaf has the largest cell.
Is the cellular material inside the leaf arranged so that the leaf is a solid mass or are there spaces left inside?
The cellular material inside a leaf is arranged with various spaces and gaps between the cells. These spaces allow for the movement of gases, such as carbon dioxide and oxygen, as well as water and nutrients throughout the leaf. This arrangement is crucial for photosynthesis and overall leaf function.
What is the area in a leaf containing many air spaces between cells so that carbon dioxide from the stomata can pass through?
The underside of the leaf.
What do lower leafs cells do?
lower leaf cells is widely spaced cells allow carbon dioxide and oxygen to pass in and out the leaf
How do the air spaces in the spongy mesophyll connect with the exterior of the leaf?
The air spaces in the spongy mesophyll connect with the exterior of the leaf through small pores called stomata. Stomata are located on the underside of the leaf and allow for gas exchange between the interior of the leaf and the surrounding environment.

The underside of the leaf.
Why do you use the lower part of the leaf to look at the stomata?
The stomata are only found on the lower face of the leaf. They connect to empty spaces within the leaf and allow exchange of gasses (CO2, O2) with the atmosphere. a process essential for photosynthesis, as well as transpiration (evaporation of water), which is critical for the proper absorbtion of nutrients through the roots (believe it or not!). These spaces do not occur on the upper (sunward) side of the leaf, because that surface is packed with photosynthetic cells.
Spaces between cells that allow the rapid movement of air within the leaf?
inter cellular space
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 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.
