What would be the advantage of locating stomata on the underside of a leaf be for the plant? (Hint: sunlight and the effect of t
ranspiration) On what types of plants would you find stomata only on the upper surface of the leaf? Why (Hint: this refers to where they are found growing)
1. Stomata are the openings on the leaf for the exchange of the water and air from the plant to the environment. It actually helps plants to breath, so it can also be seen as nostrills of the plants. They are present on either side of the leaves. Opening a stomata is like opening the doors for the exchange of the gases . This comes at a cost.
Due to sunlight and heat from the environment water content of the leaf is also remarkably lost when stomata opens, which is protected otherwise due to outer waxy layer of the leaf. To reduce this, most of the stomata are present on the lower surface of the leaves, as it will reduce the possibility of water loss due to high sunlight during the afternoon.
2. In aquatic plants you can find most of the stomata present on the upper surface of the leaf. As the plants float on the water surface, its lower epidermis is stuck to the water, hence respiration is least likely there as there is no contact of the stomata with the air.
The low-pressure system is an area where the air pressure is low and is formed under the areas of the wind divergence that occurs in the upper levels of the atmosphere.
<u>Compared to the winter the high-pressure systems tend to form where the air is cool and sinks and are generally found in the polar areas and equator is the region that forms the convective currents zones and thus leads to the rising of the warm and the formation of a low-pressure system.</u>
arsenate are the chemical compound , that contains the arsenate ion , of formula , AsO₄³⁻ . The valency of the the arsenic atom in the ion is 5 , and has a pentavalent structure .
From the given compound in the question , the compound have an arsenate ion , hence it belongs to the Arsenate family .
