Optimum Temperature & Environmental Growth Signals — NEET Biology

Which of the following statements correctly describe the essential conditions and influencing factors for plant growth and development? S1: Water provides the medium for enzymatic activities and contributes to cell turgidity for extension growth. S2: Oxygen is critical for releasing metabolic energy required for various growth activities within the plant. S3: Both macro and micronutrients are required for protoplasm synthesis and serve as primary energy sources for plant growth. S4: Environmental factors such as light and gravity primarily act as direct metabolic inhibitors, restricting overall plant development. S5: Every plant species possesses an optimum temperature range, deviation from which can be detrimental to its survival and growth. S6: Intrinsic factors like plant growth regulators operate independently of external environmental signals, solely governing internal developmental processes.
