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.
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.
Iron is a major component of red blood cells. The oxygen you breathe bonds to the iron in your red blood cells. If you had no iron in your body you would likely die.
What was the world like before Pasteur? Our understandings of the disease process is closely tied with the discovery of microorganisms. So one guess would be that more of us would be dying of disease in the absence of knowledge of microorganisms.
because if they didnt get replaced then you would lack the cells. and you would die. i think.
The three listed points of the cell theory would be that cells are the building blocks of life, all life is composed of cells, and all cells come from preexisting cells. These were found by different people.
Guard cells close stomata during high temperatures, low humidity, and drought conditions to prevent excessive water loss through transpiration. When the plant is experiencing stress, the guard cells respond by shrinking and closing the stomatal pores to conserve water.
Guard cells close to prevent excess water loss by closing the stomata, which are small openings on the surface of leaves. When the stomata are closed, it reduces the amount of water vapor that can escape from the plant through transpiration. This helps the plant conserve water during dry or hot conditions.
That would be the "guard cells". The stoma is an opening on the underside of many leaves and each stoma is bordered by a pair of guard cells that open and close the pore to allow for "transpiration" (the passage of water in either gaseous or liquid form into or out of the leaf). In hot, dry weather, the guard cells close to prevent water loss. In humid weather, the guard cells allow the pore to open and water can enter.
Guard cells are specialized cells that regulate the opening and closing of stomata in plant leaves. A false statement regarding guard cells would be that they do not contain chloroplasts; in fact, many guard cells do have chloroplasts, which contribute to their function in photosynthesis and the regulation of gas exchange. Additionally, guard cells are not involved in nutrient transport but primarily in controlling water loss and gas exchange.
sugar solution does effect the opening and closing of stomata. when stomata is treated with sucrose solution, the guard cells will loss its water content as sucrose solution is more concentrated. water will moves from higher water potential (low concentrated) to low water potential (high concentrated). thus, water moves out from guard cell to its surrounding cell. when cell loss the water, it later lost its turgidity and shrink. the shrink cell eventually become flatten and close the stomata pore. . =)
Guard cells in plant stomata regulate gas exchange by controlling the opening and closing of the stomatal pore. They swell when they take in water, causing the stomata to open and allow for gas exchange. Conversely, they shrink when they lose water, closing the stomatal pore to prevent excessive water loss.
the cell will died
If the cells of a developing plant did not differentiate into guard cells, the plant would not be able to regulate gas exchange efficiently through the stomata. This could lead to problems like loss of water through transpiration, inefficient photosynthesis, and susceptibility to environmental stress. Eventually, the plant may struggle to survive and grow properly.
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.
That would be the "guard cells". The stoma is an opening on the underside of many leaves and each stoma is bordered by a pair of guard cells that open and close the pore to allow for "transpiration" (the passage of water in either gaseous or liquid form into or out of the leaf). In hot, dry weather, the guard cells close to prevent water loss. In humid weather, the guard cells allow the pore to open and water can enter.
Keep a close eye on the books and "follow the money".
Plants close their stomata to conserve water and prevent excessive water loss during periods of drought. This helps them maintain their internal water balance and avoid wilting or damage from dehydration.
