The stomata would be narrower, thus osmosis would occur less, thus photosynthesis would be less.
The stomatal pore will become narrower. Gaseous exchange to and fro stomata will be reduced. This will affect the rate of photosynthesis in green plants.

What are the small openings on a leaf that allow gasses to leave and enter the plant'?
It is controlled by a combination of the pressures/concentration gradients of the gases involved, and the guard cells of the stomata.
What is the function of the stomata opening?
The stomata in the surface of a plant open during daylight (for most plants) and allow CO2 to be absorbed and O2 released. These gases just diffuse to and from the air via the stomata, but are reacted within the interior of the plant. [Some desert plants have their stomata closed during the day, to conserve water. They open their stomata at night, and store CO2 in a special chemical, then close the stomata during the day, but still use the sunlight to convert the CO2 into sugars and starches.]
What mechanism causes stomates to open when the guard cells are in good conditions?
The reversible uptake and loss of potassium ions (K+)
When would guard cells close the stomates?
Guard cells would close the stomata to prevent excess water loss through transpiration, normally when the weather is extremely hot or there is a lack of ground water. This is a regulatory mechanism to prevent dehydration.
True or false guard cells control the opening and closing of the stomates?
Yup. Guard cells, shaped like little kidney beans, are arranged in pairs at a stomate, with their concave sides facing each other. These concave sides have a thicker cell wall than the remainder of each cell's wall, so that when water is driven in, the guard cells swell, causing the concavities to spread apart in the middle, opening an eye-shaped slit. This is the open stomate, which lets out gasses from respiration (namely O2, and often a characteristic fragrance, like Sweet Gum trees make the woods smell sweet) and water vapor. When the turgor pressure (or internal water pressure in each cell) subsides, the cells reduce in size, and the erstwhile separated concavities of the guard cells now fully touch, closing the stomate.
How plants open and close the stomata?
A chain of events leads to an increase in the concentration of sugar in the cell sap in the vacuole of guard cell. osmotic potential of cell sap decreases and guard cells withdraw water from the neighboring cells. this increases turgid pressure of the guard cells it swells up.the swelling of the outer wall causes the guard cells to curve away from each other so increases the gap between them stomata opens). and when guard cells lose water, they become flaccid and comes closer thus stomata closes.
What would happen if the cell of a developing plant did not differentiate into guard cells?
the cell will died
What cells guard the opening and closing of the stomata?
Stomatal pores in plants regulate the amount of water and solutes within them by opening and closing their guard cells using osmotic pressure. Guard cells and adjacent subsidiary cells are involved in opening and closing of stomata.
What would happen to the gases and water in a leaf if the guard cells were closer together that is if the stoma were smaller than it is?
hey if thats a biology lab sheet i have the same one :)! but the water would not be able to get in and out of the leave as easily and as a result would die off because off too much gas building in the leaves.
Which structure controls transpiration?
guard cells
What is the role of a stomata and guard cells?
Through the stomata carbon dioxide diffuses into the plant and oxygen and water vapor diffuse out of the plant. Guard cells control the opening and closing of the stomata. Used in arid climates to control water loss for instance.
What is the of guard cells?
the function of guard cells are that they control the opening and closing of the stoma
What are the names of the specialized cells that control the aperture of the hole of the stomata?
These are called the guard cells.
What is the chemical difference between stroma and the cytoplasm?
A "stoma" is singular, whereas "stomata" is plural. Each guard cell is surrounded by two guard cells which are specialized parenchyma cells. Imagine that the guard cells are like two longish, curved balloons tied together at each end. (Each guard cell is like one of these balloons). If the balloons are both filled with air, they curve away from each other, creating a hole in the middle (a stoma). However, if the two balloons are not filled with air, they are pressed tightly together. (Guard cells are pressed tightly together by the surrounding parenchyma cells). During the day, sunlight causes the chloroplasts within the guard cells to produce sugar. (Guard cells contain more chloroplasts than surrounding parenchyma cells). Sugar builds up within the guard cells. By osmosis, water is drawn into the guard cells from the surrounding parenchyma cells, causing the guard cells to swell and close the stomata. This prevents water loss from the leaf during the heat of the day. At night, the sugar is used up, the water within the guard cells passes out of the guard cells, and the stomata open for transpiration and gas exchange: Carbon dioxide, oxygen and water vapour pass in and out of the leaves through the stomata. (Most stomata are found on the leaves of most plants, though cactus have them on their stems - because the leaves of cactus are the needles).
How is the opening and closing of stomata controlled?
The guard cells controll the opening and closing of the statoma!
What the function of guard cells?
the function of guard cells are that they control the opening and closing of the stoma
Stomata open and close in response to pressure within?
guard cells
