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.
What else can I help you with?
Which plants have sunken stomata?
generally xerophytic plants have sunken stomata
Presence of sunken stomata in leaves indicates the character of which type of plant?
Plants with sunken stomata in their leaves are known as xerophytes. These plants have adapted to dry environments by reducing water loss through transpiration. The sunken stomata help to create a humid microclimate around the leaf surface, reducing water loss.
Are stomata present in xerophytes?
Yes, xerophytes have stomata. However, they typically have adaptations to help reduce water loss through transpiration, such as sunken stomata or hairs around the stomata to create a humid microenvironment.
Why do plants in dry habitats have their stomas in a sunken pit on their leaves?
Plants in dry habitats have sunken stomata to reduce water loss through transpiration. The sunken pits create a more humid environment around the stomata, making it harder for water to evaporate. This adaptation helps the plant conserve water and survive in arid conditions.
How does a plant manages the conflict between the loss of water through transpiration and the need for C02 for photosynthesis?
By putting control over opening and closing of stomata and also creating the devices to minimize the loss of water by transpiration, such as position of stomata on the lower surface of leaf, away from sunlight, presence of hairs and sunken stomata etc.

Botanists believe that gymnosperm leaves have evolved sunken stomata below the leaf surface to reduce water loss from?
Transpiration.
Why is cacti said to have sunken stomata?
Cacti are said to have sunken stomata to minimize water loss in their arid environments. By having stomata located below the surface of the epidermis, cacti reduce exposure to dry air and lower the rate of transpiration. This adaptation helps them conserve water while still allowing for gas exchange necessary for photosynthesis. Additionally, the surrounding air within the cavity can become more humid, further aiding in water retention.
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.

How does sunken stomata lower rate of photosynthesis?
Sunken stomata reduce the rate of photosynthesis by limiting the exchange of gases between the leaf interior and the atmosphere. While they help minimize water loss through transpiration, this adaptation can also restrict the intake of carbon dioxide, which is essential for photosynthesis. Consequently, lower levels of carbon dioxide can lead to reduced photosynthetic rates, particularly in conditions where water conservation is prioritized over gas exchange.
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.
What part of the structure of the leaf minimizes water loss?
Stomata and the thickness of the leaf
What are some differences between xerophyte and phreatophyte?
Xerophytes are known for having stomata that are fewer in number, sunken, waxy and\or open only at night. Hydrophytes often lack cuticle, because there is no need to prevent water loss. stomata are larger in quantity and typically open.
