Guard cells are specialized plant cells that regulate the opening and closing of stomata, which are small pores on the surface of leaves. They control gas exchange by responding to environmental conditions, allowing carbon dioxide to enter for photosynthesis while minimizing water loss through transpiration. Their shape changes—swelling to open the stomata and shrinking to close them—facilitate these processes effectively.

What is the similarities of a human nerve cell and plant guard cell?
Both human nerve cells and plant guard cells are specialized cells that have specific functions within their respective organisms. They both have membrane-bound structures that control the movement of substances in and out of the cell. Additionally, both cell types respond to external stimuli to carry out their functions.
What is a localised part of the body specialised for particular functions?
cells
How are stem cells trnsplanted?
Stem cells are cells that have not specialised. Specialist cells can only be the one thing that they are specialised for; ie, you cannot turn skin cells into a heart, or liver cells into a brain. Stem cells have not specialised and can therefore become any type of cell. I am not sure how they are stimulated to become one kind or another, but they can. Adult stem cells are not as good as embryonic stem cells, but because harvesting embryonic stem cells requires the destruction of a human embryo it is banned in many countries.
What are the specialised cells in a flower?
Specialized cells in a flower include the guard cells in the stoma for regulating gas exchange, pollen grains for reproductive function, and trichomes for protection and secretion. Each of these cell types plays a specific role in the overall function and survival of the flower.
What is the name of the specialised cells which take in water and minerals?
it's called your dad

Your sense organs have specialised cells called?
sensory receptors - specialized nerve cells
How are blood cells 'specialised' cells?
They're specialised because their sole job is to transport oxygen to the body's cells, and carry carbon dioxide away. This is similar to white blood cells who's only job is to defend the body from invading diseases.

no they are all sexually enviroment

Which structure controls transpiration?
guard cells
What does unspecialised?
Unspecialised means no specialised function. For example ciliated cells vs nonciliated cells.
What cells guard the opening and closing of the stomata?
The guard cells are specialized cells that control the opening and closing of the stomata in plant leaves. They can change shape to regulate the exchange of gases and water vapor between the leaf and the surrounding environment.
What human body cells are specialised to prevent salmonella?
non you will die
What does unspecialised mean?
Unspecialised means no specialised function. For example ciliated cells vs nonciliated cells.
What is the of guard cells?
the function of guard cells are that they control the opening and closing of the stoma
