Answer:
Answer is C. Bacteria
Certain types of bacteria have a relationship with certain plants where they help convert nitrogen into a usable form.
Explanation:
Nitrogen is abundant in the atmosphere, but plants cannot use it because of the absence of a necessary enzyme, nitrogenase, which converts nitrogen into a usable form. So they form a symbiotic relationship (mutually-beneficial arrangement) with nitrogen fixing soil bacteria (rhizobia) which perform biological nitrogen fixation. Biological nitrogen fixation is a process in which the symbiotic nitrogen-fixing bacteria coverts atmospheric nitrogen into ammonia and organic derivatives that plants can use to synthesize proteins. This bacteria form nodules on the roots of plants like legumes in which nitrogen fixation takes place.
Both plants and bacteria benefit from this symbiotic relationship, as the plant obtains ammonia to synthesize proteins from nitrogen in the atmosphere while bacteria obtain carbon compounds from the plant produced through photosynthesis and a secure environment to grow. As the plant roots leave behind some of the usable form of nitrogen in the soil, this process also increase soil fertility.

Explanation:
<em>Jimmy was right to say organisms grow because their cells grow.</em>
<u>The growth of organisms can happen in terms of an increase in the number of cells they have (through mitotic cell division) or an increase in the volume of the cells with or without an increase in the number of cells. </u>
A good example is found in plants, most of which undergo an increase in size without any increase in the number of cells in their bodies. The uptake and storage of water in the vacuole produces a pressure that pushes on the cell walls, causing an increase in length, girths, and other growth features of the cells of plants.
