Nitrogen, even though makes for about 78% of our atmosphere, and is by far the most abundant gas in it, we can not use it because it can not be taken out of the atmosphere as it is. If we take nitrogen in the form as it is in the atmosphere it is useless for both humans and plants. It has to go through a process of ''fixation'' first before we can actually use it in our food.
The mechanics of cytokinesis are not yet completely understood, but a great deal is known about the critical timing of its events and other aspects of the final step in the cycle of any one cell. The four stages of cytokinesis are initiation, contraction, membrane insertion and completion .
Answer:
Chlorophyll absorbs the light needed for photosynthesis.
Explanation:
Photosynthesis is the process where green plants manufacture their food. During photosynthesis, carbon dioxide combines with water in the presence of light energy from the sun to produce glucose and oxygen as a byproduct.
From the statements listed, chlorophyll does not combine with water. Chlorophyll is a pigment in plant that simply absorbs light energy from the sun which is necessary for the process of photosynthesis. This makes photosynthesis a simple process in which light energy from the sun is transformed to chemical energy.
