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 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 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 do the spongy mesophyll cells do?
Trap plenty of air in the air spaces
How do guard cells regulate the exchange of gases between a leaf and the air?
The guard cells regulate the exchange of gases between the leaf and air through the use of openings called stomatal pores.
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 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.
Spaces between cells that allow the rapid movement of air within the leaf?
inter cellular space
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 does the leaf petiole of a water hyacinth helps it to float?
It contains air spaces (aerenchyma) within the cells of the petiole
What is the function of the air spaces in a leaf?
Gas exchange
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.
Explain the purpose of the air spaces in the leaf tissue?
There are large spaces in a leaf because it is for storing water and carbon dioxide which will be used for photosynthesis. The large air spaces are usually found in the spongy layer of the mesophyll.
What is the layer of the leaf that contains the large air space?
the spongy layer has alot of air spaces so gases can diffuse in and out of the leaf easily
What do the spongy mesophyll cells do?
Trap plenty of air in the air spaces
What side of a leaf are stomata located?
The lower surface of the leaf has the stomata. You can see the reason for this if you cut a leaf in half from upper side to lower side. The upper portion of the leaf consists of tightly packed cells that are full of chloroplasts for taking in light. The lower half of the leaf is made up of loosely arranged cells. This allows room for air to enter the lower part of the leaf through the stomata and contribute carbon dioxide and take away oxygen. The upper surface of the leaf is covered by the cuticle which prevents dehydration, as such the stomata cannot be located or function on the upper surface
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.
