Question

When stomata are present only on the lower side of leaf, the condition is called as
A. epistomatic
B. Hypostomatic
C. Amphistomatic
D. None of the above

Answer 1

Stoma happens in the epidermises of any of the elevated pieces of plants. It happens in Bryophytes, Pteridophytes and Spermatophytes. In Bryophytes stomata are found in the containers of Anthocerotopsida and Bryopsida. In Marchantiopsida stomata are missing; rather pores are available on the outside of thalli. The pores stay open for all time.

Complete answer:
The phylum Pteridophyta has stomata in the entirety of its four divisions. Huge stoma happens in Psilopsida, Lycopsida and Pteropsida. Psilopsida (ex. Psilotum) and Sphenopsida (ex. Equisetum) have stomata that are bound to longitudinal sections of the aeronautical stem edges. In Lycopsida stomata are available on leaves and stems.

Stomata are additionally present in the inward and external surfaces of organic products, in the outside of seeds, inside units and in the skins of bananas. The presence of stoma is additionally recorded from rhizomes. The chlorophyll-less parasitic plants like Monotropa and Neottia need stomata. Another sans chlorophyll plant Orobanche has stomata on the stems. Plants having a place with Balanophoraceae, Monotropaceae and Rafflesiaceae are without chlorophyll and there are reports that these plants need stomata. The lowered oceanic plants don't have stomata.

So, the correct answer is "option B".

Note: Normally stomata are missing in roots. Be that as it may, in seedling foundations of Ceratonia siliqua and Pisum arvense stoma is watched. Non­functional stoma is found in pale skinned person plants, petals, staminal fibers (ex. Colchicum), carpel and seeds. A leaf is supposed to be hypostomatous where stomata are available on a baxial surface as it were. Most three types of dicotyledons have such leaves. Ex. Ficus, Nerium and so on.
