Photosynthesis produces oxygen and water. Photosynthesis is the result of a cycle. Humans use oxygen for respiration, the product produced from human respiration is carbon dioxide. Then plants absorb carbon dioxide from the air and turn it into oxygen with photosynthesis, this goes on and on as a cycle.
for instance in humans, the somatic cells include 46 chromosomes which is the diploid wide variety (2n) and each sperm and egg has 23 chromosomes wherein one of them is the sex chromosome.
