It is possible, during times of drought, for water that has been removed from the root zone of the plant as a result of downward percolation to travel back up into the root zone through capillary movement.
This will be discussed in further detail below.
<h3>What exactly is the movement of capillaries?</h3>
Percolation is the process by which water moves downward through the root zone of a plant. When circumstances are dry, water that has traveled downward through the root zone as a consequence of percolation may possibly travel back up into the root zone of the plant. In general. capillary movement and migration
Only when the adhesive forces in the liquid are greater than the cohesive forces, which always produce surface tension, can capillary action take place. Capillary action is a physical phenomenon.
In conclusion, the phenomenon known as capillary action refers to the movement of a liquid through a limited space either without the assistance of any external forces, such as gravity, or even in opposition to such force.

C. South Africa goes through another economic recession
The Paraguay and Parana Rivers jointly form a 3,302-kilometer waterway system connecting Argentina, Brazil, Bolivia, Paraguay, and Uruguay. It is a major transportation route between the continent's interior and the Atlantic Ocean through the Rio de la Plata, and carries nearly 80 percent of Paraguay's trade.

Explanation:
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.
