Where are stomata found on lotus leaves?

Most plants produce stomata on the undersides of their leaves to absorb carbon dioxide and give off oxygen, both needed for the plant’s food production cycle. Lotus plants, by contrast, have their stomata on the upper sides of their leaves, exposed to the air. This is due to the fact that since the plant has floating leaves, there will be no stomata on the lower epidermis and the plant will absorb gases directly from water through the cuticle.

Where are stomata found on lotus leaves?
Seeds, rhizomes, moisture, sunlight and muddy soil, humble components that evolved into a mythical symbol, a spectacular water lily, the renowned, coveted and treasured lotus flower. Eighty species of water lilies are grown, eaten and appreciated around the world, but none as spectacular as the Asian lotus, symbol of purity and loveliness.

People treasure the lotus not only for its spectacular blooms in shades of white (the rarest), of creamy yellow, read and pink, but also for its food value. Several parts of the lotus are edible and quite tasty. The plant’s habitats create a symbiotic relationship for a variety of fish and amphibians, providing food and shelter. Many other creatures -- insects, water mites, freshwater sponges and tiny microbes -- make their homes around water lilies, too. The slender stalks of the lotus act as deterrents for excess wave action, thereby helping to keep the water calm.













Water lilies are unusual in many ways. The long stalks rise from their root systems, actually underwater rhizomes that grow on the bottom of a muddy pond or lake, bursting through the water’s surface. Waxy-coated leaves float on the lake or pond surface, repel water and keep the upper surface of the plant dry. Most plants produce stomata on the undersides of their leaves to absorb carbon dioxide and give off oxygen, both needed for the plant’s food production cycle. Lotus plants, by contrast, have their stomata on the upper sides of their leaves, exposed to the air.



The epidermis is the outer multi-layered group of cells covering the leaf. It forms the boundary between the plant and the external world. The epidermis serves several functions: protection against water loss, regulation of gas exchange, secretion of metabolic compounds, and (in some species) absorption of water. Most leaves show dorsoventral anatomy: the upper (adaxial) and lower (abaxial) surfaces have somewhat different construction and may serve different functions.



The epidermis is usually transparent (epidermal cells lack chloroplasts) and coated on the outer side with a waxy cuticle that prevents water loss. The cuticle may be thinner on the lower epidermis than on the upper epidermis, and is thicker on leaves from dry climates as compared with those from wet climates.



The epidermis tissue includes several differentiated cell types: epidermal cells, guard cells, subsidiary cells, and epidermal hairs (trichomes). The epidermal cells are the most numerous, largest, and least specialized. These are typically more elongated in the leaves of monocots than in those of dicots.



The epidermis is covered with pores called stomata, part of a stoma complex consisting of a pore surrounded on each side by chloroplast-containing guard cells, and two to four subsidiary cells that lack chloroplasts. The stoma complex regulates the exchange of gases and water vapor between the outside air and the interior of the leaf. Typically, the stomata are more numerous over the abaxial (lower) epidermis than the adaxial (upper) epidermis.
Reply:upper side of the leaf
Reply:Both sides, but more on lower side..The upper side is covered by waxy layer
Reply:In lotus,the stomata is found on both sides of leaves which are waxy.
Reply:EPIDERMIS
Reply:jo lotus ki pattiyan hoti hain na , unmein stomatas jo hote hain na , woh na uper hote hain takee woh hawaa mein se na saans le sake.samjhee ya samjhaayen? hum bihaari hain. saari
Reply:in lotus leaves stomata r found on upper surface only.its stomata is of epistomatous type .other plants havin epistomtous type of stomata is water lily and victoria.
