Question

The leaves having equal stomata on both the surfaces are called as
(A) Amphistomatic
(B) Hypostomatic
(C) Epistomatic
(D) Astomatic

Answer 1

The leaves are the inexperienced structure that is present laterally on branches and show photosynthesis and these are the food preparing factory of the plant and perform transpiration process by means of stomatal opening, these opening also the web page of trade of gases.

Complete answer:
The flowers undergo two sorts of leaves that are named as the isobilateral and dorsiventral leaf in one of-a-kind plant groups. A dorsiventral leaf is discovered in dicots plant in which mesophyll tissue parenchymatous and it is differentiated into two sorts of parenchymatous cells that identify as palisade and spongy tissue, palisade present on the higher floor of the leaf while spongy current on the lover aspect of the leaf.

Bulliform cells are absent in such a type of dorsiventral leaf which performs rolling of the leaf. Stomata structure, which is minute opening present majorly on leaves, in the dorsiventral type of leaf stomata are existing less in quantity or absent on the top facet whilst massive in range on the lower side
In the case of the isobilateral leaf, mesophyll is no longer differentiated and the bulliform cell is present. Such a type of isobilateral leaf is discovered in the monocot plant group. Stomata in isobilateral leaves are equally dispersed on each aspect of the leaf.

Now let us find solution from given options:
(A) Amphistomatic: when stomata are present on both the surfaces it is termed as amphistomatic leaf.
(B) Hypostomatic: When stomata are present solely on the decreased side of the leaf that is mainly on the lower side, it is called as hypostomatic. This is a situation when leaves have stomata typically on the underneath, i.e., the foliar abaxial surface.
(C) Epistomatic: when stomata are present only on the upper surface it is termed as epistomatic leaf
(D) Astomatic: when no stomata is present at all.

Hence the correct answer is option ‘A’.

Note: The stomata are present all over the body of the plant however their range varies and majorly found in leafs bulliform cells that are existing in monocot plant leaves are additionally called empty cells and these bulliform cells are the change of adaxial epidermal cells and veins.
