S phase
Explanation:
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.

Answer:
The plant on the left does not accumulate significant photochlorophyll or carotenoids, so it will become very pale on the shoot tip, while the plant on the right will continue to grow upward as auxin is uniformly distributed around the tip of the right plant.
Explanation:
Phototropism is the orientation of a plant in response to light, either towards the source of light or away from light. Positive phototropism is growth towards light, while negative phototropism is away from light.
Auxin are substances that promote and regulate the growth and development of plants. Auxin escapes light making the area in the shade elongate more so the plant tip moves towards the light.
