There are just in plant cells hope this helps
The sucrose move in source to sieve by active transport.
<h3>What is active transport?</h3>
Active transport is a type of transport in which the cell expends energy to move solutes against their concentration gradients. The sodium-potassium pump is an example of active transport. Active transport differs from passive transport in that the cell does not expend energy.
In this case, the sucrose moves from companion cells into source to sieve elements by active transport. This reduces the water potential of the source to sieve element by osmosis, which increases the hydrostatic pressure.

Answer:
granular cells of the juxtaglomerular apparatus
Explanation:
Renin is a secreted hormone, stored and produced by granular cells. This enzyme is responsible for regulating the water gradient in the human glass and blood pressure. This enzyme helps regulate the extracellular gradient in the blood cell plasma and controls any problems that may appear in the arteries or in all blood vessels in the body.
Answer:
Determining a substance's physical or chemical identity. What are the two main requirements for identification? The adoption of testing procedures that give characteristic results for specific standard materials and the number and type of tests needed to identify a substance to exclude all other substances.
Yes, a plant would as long as a living creature is in the area to exchange oxygen and carbon dioxide. It is not totally necessary for other plants to be in the immediate vicinity but is necessary for all living things to live. As mentioned before carbon dioxide and oxygen must be exchanged.
