Explanation:
Mutations are alterations in the genetic code that may occur due to environmental or chemical mutagens. Mutagens, are substances or agents that induce changes in the genetic code.
Photosynthesis is a complex biochemical process; plants convert solar energy into chemical energy as sugars like the polysaccharide glucose. They also use inorganic carbon from
along with
.
Plants photosynthesize in their leaves- these organs contain tissues for
intake, along with the chloroplasts and mitochondria, the sites of photosynthesis and respiration. If the number of leaves are reduced, this reduces the amount of tissue capable of carrying out this essential process, limiting the plant's chance for meeting its energetic needs, and thus survival.
The element is Oxygen (O subscript 2).
