Which plants have sunken stomata?
generally xerophytic plants have sunken stomata
Does a cacti open its stomata during the day?
no!
What is sunken stomata?
Sunken stomata are like normal stomata except they are literally sunken into the leaf a few micrometres. they are usually in a little chamber- imagine a tiny C shape cut into the leaf, and the stomata being on the inside curve of the the C, and the ends of the C being the outside of the leaf. they help prevent transpiration and loss of water vapour as they are more protected from external conditions that speed up transpiration such as winds than stomata which aren't sunken. sunken stomata are usually protected by hairs in the chambers, and these hairs are called trichomes. they trap the water vapour, whcih also helps prevents water loss.
Where are the stomata on cactus?
The stomate are located in the same place as other plants, leaf and stems. Their stomate are much smaller and sometimes sunken deeper into the surfaces to help keep water loss at a minimum. Also, the stomate on catus only open at night when it is cool outside.
Presence of sunken stomata in leaves indicates the character of which type of plant?
hydrophytes
How have plants dealt with the problem of water loss?
Plants have tried to minimize the water loss by some adaptations like presence of sunken stomata only on the lower side of the leaf, cuticle and waxy depositions on the epidermal cells, leafless plants (certain cacti), presence of hairs, spines etc.
Why stomata are present only on lower epidermis in nerium leaf?
as nerium is a xerophyte i.e.as it cannot take in sufficient amount of needed water,the sunken stomata are present in the lower epidermis to reduce loss of water by transpiration.there are also certain hair present in the sunken stoma to protect it.
Botanists believe that gymnosperm leaves have evolved sunken stomata below the leaf surface to reduce water loss from?
Transpiration.
Does the cactus have a stomata?
Yes. The cacti may practice a delayed form of photosynthesis because they must close their stomata in the daytime but they, like all other plants, must take in carbon dioxide and release oxygen and water through those stomata.
What are 2 adaptations of gymnosperms?
the needels have a very thick cutical that helps pervent water loss as well as a sunken stomata
Why would closing their stomata during the day be an advantage for the cacti?
During mid day when the intensity of light and day temperature is higher
How has the succulent adapted its stomata to prevent too much water loss?
it does does . god works . don't ever question gods works .
