Question

on this cloudy morning with limited sunlight, how do the sunflowers cells obtain energy for growth and cellular processes? select one of four plant cells switch to using nitrogen from soil as their primary energy source cells use stored glucose through cellular respiration to generate atp for cellular work photosynthesis automatically increases efficiency to fully compensate for the low light conditions plant cells stop all energy - requiring processes until full sunlight returns to the garden remaining attempts: 1

Explanation:

• Option 1: Nitrogen is not an energy source; plants use it for other purposes like protein synthesis, so this is incorrect.
• Option 2: Plants store glucose (from photosynthesis during sufficient light) and use cellular respiration (which doesn't require light) to break it down into ATP for energy, even in low - light conditions. This is correct.
• Option 3: Photosynthesis efficiency doesn't “automatically increase” to fully compensate for low light; it depends on light intensity, and low light limits photosynthesis. So this is incorrect.
• Option 4: Plant cells don't stop all energy - requiring processes; they need energy for basic functions like maintaining homeostasis, so this is incorrect.

Answer:

Cells use stored glucose through cellular respiration to generate ATP for cellular work
