Question

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

Explanation:

• Photosynthesis is the process where plants convert light energy (from sunlight) into chemical energy (stored in glucose). So, "Photosynthesis transforms light energy into chemical energy" is true.
• Chlorophyll is the pigment in plant cells (in chloroplasts) that absorbs light energy. Thus, "Chlorophyll captures light energy" is correct.
• According to the law of conservation of energy, energy is not created. In photosynthesis, carbon dioxide and water are used to make glucose (a form of chemical energy) using light energy. So, the statement "Photosynthesis creates energy from carbon dioxide and water" is false.
• Plant cells, like other eukaryotic cells, perform cellular respiration. In cellular respiration, glucose (food) is broken down to release chemical energy (in the form of ATP). So, "Plant cells use cellular respiration to get chemical energy from food" is true.

Answer:

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