Question

select all the true statements about how plants use and change energy. plant cells use cellular respiration to get chemical energy from food. chlorophyll captures light energy. photosynthesis transforms light energy into chemical energy. photosynthesis creates energy from carbon dioxide and water.

Explanation:

• Cellular respiration in plant cells breaks down food (glucose) to release chemical energy (ATP).
• Chlorophyll is the pigment in chloroplasts that absorbs light energy.
• Photosynthesis uses light energy (captured by chlorophyll) to convert carbon dioxide and water into glucose (chemical energy) and oxygen. Energy is not created (as per the law of conservation of energy), so the statement “Photosynthesis creates energy from carbon dioxide and water” is false.

Answer:

• Plant cells use cellular respiration to get chemical energy from food.
• Chlorophyll captures light energy.
• Photosynthesis transforms light energy into chemical energy.
