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.
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.
Is a leaf a cell?
Palisade cells and the spongey mesophyll. The upper and lower epidermis aren't cells but the are also in a leaf.
Which layer has the largest cells in elodea leaf?
The lower epidermis of the elodea leaf has the largest cell.
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.
How do the air spaces in the spongy mesophyll connect with the exterior of the leaf?
Through "stomas" - little gaps in the lower epidermis of a leaf. These are bordered with guard cells.
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
What are lower leaf cells?
hummus dip

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 is the transparent layer of cells on the bottom of the leaf that acts like a skin named?
Lower epidermal cells.
How does the leaf petiole of a water hyacinth helps it to float?
It contains air spaces (aerenchyma) within the cells of the petiole
