What organelles do guard cells contain that are absent in the skin cells of a leaf?
me
Which process illustrates a feedback mechanism in plants?
A process that illustrates a feedback mechanism in plants is when the guard cells change the size of a leaf's openings to control gas exchange. Guard cells are located in the epidermis of leaves.
What is the whole between two guard cells in a leaf called?
It's called a stoma (plural stomata) and its function is to allow carbon dioxide to enter the leaf for photosynthesis. The guard cells sre responsible for regulating the size of the stoma.
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 guard cells in a plant do?
The guard cells in a plant are responsible for opening and closing the stomata. The stomata is a tiny opening on the blade of a leaf that allows for carbon dioxide to enter and water + oxygen to be released. The guard cells are triggered by concentrations of potassium ions.
Can guard cells carry out photosynthesis?
No Guard cells are cells that close when there is dry weather, preventing the leaf from becoming dehydrated
What are pores surrounded by guard cells in the epidermis of a leaf?
Stomata are pores surrounded by the guard cells.
What organelles do guard cells contain that are absent in the skin cells of a leaf?
me
What part of the leaf can you find chlorophyll?
In the palisade cells, spongy cells, and guard cells.
What do guard cells have the ability to absorb from the leaf?
water
What tissues of a leaf have guard cells and stomata?
Epidermis
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.
Where are chloro plast mostly confined in a leaf?
in guard cells......believe me!
Which process illustrates a feedback mechanism in plants?
A process that illustrates a feedback mechanism in plants is when the guard cells change the size of a leaf's openings to control gas exchange. Guard cells are located in the epidermis of leaves.
How do carbon dixide get into the leaf?
it gets it by going through the guard cells and stoma
The interaction between guard cells and a leaf opening would not be involved in what?
The interaction between guard cells and a leaf opening would not be involved in the process of photosynthesis. Instead, the interaction between guard cells and a leaf opening is responsible for regulating the opening and closing of the stomata, which affects gas exchange and water loss in plants. This helps to maintain proper hydration and gas balance within the leaf.
What is the role of guard cells do in the leaf?
Guard cells change shape to open and close stomata. When they are flaccid, the stoma is closed. When they are full of water and firm, the stoma is open. There are 2 guard cells controlling a stoma. Water enters guard cells by osmosis and they change shape.
