Answer: Oxygen
Explanation: Photosynthesis is a process by which plants use carbon dioxide, water and sunlight to produce glucose and oxygen.
Photosynthetic reactions are divided into two phases: 1). light dependent reactions and 2). light independent reactions.
1) In light dependent reactions, chlorophyll and other light absorbing pigments absorb light energy and conserve it as ATP and NADPH with the simultaneous liberation of oxygen. This reaction occurs only when plants are illuminated. In light reactions, light energy is used to split water molecules into hydrogen ions and oxygen, the hydrogen ions produced are transferred to NADP+ to form NADPH, ATP is also produced in light dependent reactions.
2) In light independent reactions, ATP and NADPH produced in the light dependent reactions are used to drive the light independent reactions in which ATP and NADPH are used to reduce CO2 to form trioses, starch, sucrose and other products derived from them.
Meiosis in reproductive organs (testes and ovary) produce gametes. Each human cell including reproductive cells contains 23 pair of chromosomes. Meiosis separates the two chromosomes from each pair thus, each gamete receives only one copy of each chromosome. Therefore, each gamete has 23 new chromosomes, one from each of the 23 pairs. During meiosis, exchange of chromosome segment between copies of a pair of chromosomes. The exchange of chromosome segments creates new combinations of genes which enhances genetic variability within a species.
Answer:
Answer is Calvin cycle.
Explanation:
Calvin cycle is very important to plants because it helps in the conversion of organic products for the usefulness of plants. This is because the carbon dioxide and water are converted to glucose, which is useful to plants.
Calvin cycle can be explained as the production of glucose through the use of chemical energy from NADPH and ATP, produced in light reactions, to convert the atmospheric carbon dioxide to RuBP, which is a five-carbon molecule.
