Question

which of the following statements is not true? * both phases of photosynthesis require sunlight. plants require different amounts of sunlight and water. chlorophyll absorbs blue and red light. chloroplasts are the parts of the cell where photosynthesis takes place.

Explanation:

1. Analyze the first option: Photosynthesis has two phases, the light - dependent phase (requires sunlight) and the light - independent phase (Calvin cycle, does not require direct sunlight). So the statement "Both phases of photosynthesis require sunlight" is false.
2. Analyze the second option: Different plant species have different requirements for sunlight (e.g., shade - loving plants vs sun - loving plants) and water (e.g., succulents vs aquatic plants), so this statement is true.
3. Analyze the third option: Chlorophyll mainly absorbs blue and red light and reflects green light (which is why plants appear green), so this statement is true.
4. Analyze the fourth option: Chloroplasts contain chlorophyll and are the organelles in plant cells where photosynthesis occurs, so this statement is true.

Answer:

A. Both phases of photosynthesis require sunlight
