Sunken stomata are present in

Nerium, Pine, and Acacia are just a few examples of plants that have Sunken Stomata. Plants that are largely adapted to thrive in xerophytic settings have stomata that are recessed in areas where they need to minimize their rate of transpiration. For e.g. Pinus, dracaena, yucca, opuntia etc. Why are stomata sunken in xerophytes? Stomata in xerophytes have a sunken appearance because they are positioned within a cup-like depression (e.g., Nerium). Xerophytic plants have evolved this mechanism to cut down on the amount of water they lose. Does Nerium have sunken stomata? It is a member of the Apocynaceae family of plants. Nerium is distinguished by its sunken stomata, which are an adaptation that protects the plant from losing water through transpiration. CAM plants, such as Nerium, are mostly succulent xerophytes; the stomata in these plants are found in pit-like structures of a tiny size. What are stomata in plants? Stomata are the apertures that may be observed on the epidermis of the young stems and leaves of plants. Each stoma is protected by a barrier consisting of two guard cells, which are specialized epidermal cells. Which of the following plant is sunken? Stomata in xerophytes have a sunken appearance because they are positioned within a cup-like depression (e.g., Nerium). Xerophytic plants have evolved this mechanism to cut down on the amount of water they lose. What is sunken stomata and where it is found? A sunken stomata is a stomata that is located in a tiny p...

Tissue Organization in Leaves All three tissue types are represented in leaves. The epidermis represents the dermal tissue, the mesophyll that fills the leaf is ground tissue, and the vascular bundles that form the leaf veins represent vascular tissue (Figure \(\PageIndex\): A cross section through a eudicot leaf. The upper epidermis is a single layer of parenchyma cells. There are no stomata present in the upper epidermis of this leaf. Below the epidermis, cells (appearing pink due to staining of the nuclei and chloroplasts) are arranged in columns, forming the palisade mesophyll. Beneath the palisade mesophyll is the spongy mesophyll. The cells are approximately the same size as the palisade mesophyll, but there are large intercellular spaces between them. The lower epidermis is another single layer of parenchyma cells, but several stomata (flanked by guard cells) are visible in this epidermal layer. A large vascular bundle is in the center of the leaf. The xylem (stained pink) is on the top and the phloem is on the bottom.

Q. What are sunken stomata? Explain with an example? Sunken refers to something hidden; thus, sunken stomata buried or not completely visible to the surface are known as stomata. They are found in a layer of the epidermis or beneath the plant’s leaves. A tiny pit contains these stomata. Stomata that have sunk into the leaves are known as sunken stomata. A tiny pit located in the inner leaf layers contains them. These stomata evolved as a response to plants flourishing in water-scarce environments. They protect plants from losing water by limiting water vapour from escaping from air current flow or transpiration. The small pit size prevents water from escaping. Trichomes, as well as cuticles, also protect the pores. This adaptation is most noticeable in plants that grow in dry environments, where a large amount of water is lost through transpiration and drying winds. This aids the survival of such plants in a dry environment. Stomata that were not constantly exposed to the surface were referred to as “sunken.” It’s in a little hole that shields the existing water vapour from air currents, reducing leaf water loss. This sunken stomata characteristic is present in the leaves of succulent xerophytes (hot desert plants), especially gymnosperms exposed to high temperatures. Nerium, Pine, Acacia, and other plants with SUNKEN STOMATA. Plants that thrive in xerophytic environments have sunken stomata to lower the rate of transpiration. For example, Pinus, Dracaena, Yucca, and Opunt...

Stomata are tiny holes found in the underside of leaves. They control water loss and gas exchange by opening and closing. … In bright light the guard cells take in water by osmosis and become plump and turgid . In low light the guard cells lose water and become flaccid , causing the stomata to close. Why stomata open during day and close 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 CO 2 diffusion when light is available for photosynthesis, and close at night to limit transpiration and save water. Which sto...
