By intruding mutations, which are the ultimate source of biological diversity. I think this is it.
Answer:
Oxygen
Explanation:
Oxygen is the by product of photolysis during photosynthesis whereby water molecules are split to form protons (H+ ions), electrons and oxygen (by product).
Oxygen is not needed during any of the reactions in photosynthesis and Calvin cycle and will not affect the rate of photosynthesis or possibility of photosynthesis occurring. However, it will affect the process of aerobic respiration instead.
Carbon dioxide is needed in carbon fixation during the Calvin cycle. Without it, 6 carbon sugars cannot be formed.
Water is needed for photolysis to produce protons (maintain the electrochemical gradient) and electrons (to replenish lost electrons)
Chlorophyll are pigments that harvest light energy to excite electrons produced from photolysis of water to be passed down the electron transport chain.
Light is needed as a source of energy to energise the electrons
Answer:
carbon dioxide at normal atmospheric concentrations is limiting for the metabo- lism and growth of most land plants of the world. These plants share a comparable photosynthetic metabolic pathway, termed C3 photosynthesis. With an increase in CO2 there is an increase in photosynthesis and growth.
Explanation:
A single piece of coiled DNA is called a plasmid.
