S phase (synthesis phase) is the part of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Accurate and accurate DNA replication is needed to counter genetic exceptions which often lead to cell death or disease. DNA replication occurs during this S (synthesis) phase. Gap 2 (G2): During the gap between DNA structure and mitosis, the cell will remain to grow and design new proteins.
In the process of photosynthesis, plants that contain chlorophyll utilize carbon dioxide and water using energy from sunlight that is absorbed by chlorophyll to make glucose + oxygen.
