Verified step by step guidance

Understand the basic functions of photosynthesis and cellular respiration. Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy stored in glucose. Cellular respiration is the process by which cells convert glucose into usable energy (ATP).
Recognize the role of gases in both processes. Photosynthesis involves the uptake of carbon dioxide (CO₂) from the environment and the release of oxygen (O₂) as a byproduct. Cellular respiration involves the uptake of oxygen (O₂) and the release of carbon dioxide (CO₂) as a byproduct.
Identify the organelles involved in each process. Photosynthesis occurs in the chloroplasts of plant cells, while cellular respiration occurs in the mitochondria of both plant and animal cells.
Consider the energy transformations. Photosynthesis converts light energy into chemical energy stored in glucose, while cellular respiration converts the chemical energy in glucose into ATP, which is used by cells for energy.
Conclude that both processes involve the exchange of gases with the environment, which is a key similarity between them. Photosynthesis exchanges CO₂ and O₂, while cellular respiration exchanges O₂ and CO₂.
