Why do lotus and water lily have stomata on the upper surface of the leaf?
The stomata have to be able to access air easily as its purpose is to take in and give out carbon dioxide oxygen. Since both the water lily and lotus are water plants partially submerged in water, air would be more easily accesible from the upper surface.
Where are the stomata on cactus?
Stomata on cacti are typically located on the stems and sometimes on the ridges or valleys of the plant. They are often found in clusters on the surface of the stem, allowing for gas exchange and transpiration in these water-efficient plants.
How does the stomata density affect the water loss?
Stomata density directly affects the rate of transpiration (water loss) in plants. Higher stomata density means more openings for water vapor to escape, leading to increased water loss. Conversely, lower stomata density reduces the rate of transpiration and helps plants conserve water.
Why does the cactus make more use of dew than the mesquite bush?
The mesquite (Nahuatl mizquitl) draws on three sources of water whereas a cactus depends mainly on one.Specifically, the cactus depends upon water vapor taken in by the stem's pores and moisture taken up through its roots. The mesquite also takes in water vapor by its stomata, and soil moisture through its roots. But additionally, it has a 190 foot/58 meter long taproot that draws moisture from the water table. The plant can coordinate the use of all sources, or switch suddenly back and forth in its reliance. Consequently, the mesquite makes more water droplets than the cactus.
How often to water yucca cactus growing outdoors?
First off, the yucca is not a cactus. It is more closely related to the lily than a cactus. If you live in a desert climate, once it has become established it should survive with little watering. If your area has received little rainfall you may give it a good watering a couple times per month. Be careful, however, to not over water and water very little in winter or the plant may be killed by root rot.
How can cactus be more useful than a rose?
cactus has water for animals and it is a home for most desert creatures
How do deep roots help the cactus?
it absorbs more water
Why does having too much stomata increase water loss?
Having too many stomata increases water loss because the stomata are the primary sites for water vapor to exit the plant during transpiration. When there are more stomata, the rate of transpiration increases, leading to higher water loss from the leaves. This can be detrimental to the plant if it cannot absorb enough water to compensate for the excess loss.
Why does a cactus planted in the ground outdoors will need more water than a cactus in a pot inside?
inside the weather conditions are more controlled than outside. the cactus usually get larger outside
Why are there more stomata on the lower side of a leaf?
Stomata are more abundant on the lower surface of a leaf to minimize water loss due to transpiration. This positioning helps to reduce the exposure of stomata to direct sunlight and hot, dry air, thereby conserving water within the plant. Additionally, having more stomata on the lower side also helps with efficient gas exchange for photosynthesis.
How much water a plant need to growe?
That depends on what kind of plant it is. Some plants, such as cactus, do not need much water. Other kinds of plants need more. So you would have to ask about a specific plant in order to get a specific answer.It really depends on the plant. Some plants need more water than others, such as a cactus and a bean ,the bean needs more water than the cactus because the cactus stores water and beans don't.
Would the stomata open or close if the CO2 concentration decrease?
The stomata would likely close if the CO2 concentration decreased. Closing the stomata helps conserve water and prevents excessive loss of water through transpiration when there is a reduced need for CO2 uptake due to low concentrations in the air.
