What would happen to the plant if it did not have stomata on the leaves?
Ans: If stomata are not present in the leaves of the plants then, the Carbondioxide would not be able to enter the plant and also, plant would not be able to remove excess water. Due to this, the process of photosynthesis would not take place and plant will die due to excess water and no food.
Why are stomata on the bottom of leaves?
Specialized cells known as guard cells surround stomata and function to open and close stomatal pores. Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis. The majority of stomata are located on the underside of plant leaves reducing their exposure to heat and air current.
What do you think would happen to a plant leaf if the stomata were on the top side of the leaf and always open?
If stomata were on the upper epidermis (the top side of the leaf), the direct sunlight hitting the leaf would cause more water to be lost through the stomata because of evaporation.
Why are there no stomata on the lower side of the leaf?
Explanation: All surfaces of the leaf have some amount of stomata for regulating gas exchange for photosynthesis. However, the lower epidermis (the underside of the leaf) has more, because it is more often in the shade and so it is cooler, which means evaporation won’t take place as much.
What happens if stomata not work properly?
If stomata is not present in plants plants will not be able to breathe….. mean plants will not be able to take co2 in and because of this process of photosynthesis will not take place and plant will not able to make their food and will not release o2 which is necessary for human beings to live.
What would happen if stomata were always open?
If the stomata were constantly open, plants would lose too much water via evaporation from the leaf surface, a process called transpiration. This is the basis for the opening and closing of a stoma, known as stomatal movement, which controls gas exchange necessary for photosynthesis and limits water loss.
What are the 4 environmental conditions that will cause the stomata to close?
The four factors affecting opening and closing of stomata are: (1) Light (2) Water Content of Epidermal Cells (3) Temperature and (4) Mineral Elements. Even during the day, guard cells may close stomata if a plant is losing water too quickly.
Is stomata open at night?
Stomata are mouth-like cellular complexes at the epidermis that regulate gas transfer between plants and atmosphere. In leaves, they typically open during the day to favor CO2 diffusion when light is available for photosynthesis, and close at night to limit transpiration and save water.
Which stomata open at night?
Many cacti and other succulent plants with CAM metabolism open their stomata at night and close them during the day.
Which side of the leaf loses more water?
The results show that most transpiration happens from the lower surface of the leaf: coating the upper surface caused water loss similar to coating no surface at all (leaf 2 vs leaf 1) coating the lower surface caused water loss similar to coating both surfaces (leaf 3 vs leaf 4)
What triggers stomata to open?
Stomata are composed of two guard cells. These cells have walls that are thicker on the inner side than on the outer side. This unequal thickening of the paired guard cells causes the stomata to open when they take up water and close when they lose water.
