There are small tubes that connect all parts of a plant or a tree with the root. The root then applies root pressure to the nutrients and the nutrients and the water are pumped towards the upper parts through these small tubes.
Increasing the number of stomata per unit surface area of a leaf when atmospheric carbon dioxide levels decline is most analogous to a human
B. putting more red blood cells into circulation when atmospheric oxygen levels decline.
<h3>What are stomata?</h3>
The stomata are apertures in the epidermis, each bounded by two guard cells. There are small openings on the lower surface of the leaves. These pores are called stomata. Loss of water from the stomata creates an upward pull, that is suction pull, which helps in the absorption of water from the roots. That is helpful for the transpiration process. They help in exchange for gases. Any of the tiny pores or openings in the epidermis of leaves and young stems are referred to as a stomate, sometimes known as a stoma, the plural of which is stoma or stomas. On the underside of the leaves, stomata tend to be more numerous. They enable the exchange of gases between the atmosphere outside and the leaf's branching network of interconnected air canals.
