Photosynthesis
Photosynthesis is the process by which plants and other organisms use the energy from the sun to convert carbon dioxide and water into glucose and oxygen. The process takes place in the chloroplasts of plant cells and is essential for life on Earth.
Role of Chlorophyll in Photosynthesis, Photosynthesis and cellular respiration review worksheet
Chlorophyll is a green pigment that absorbs light energy from the sun. This energy is used to split water molecules into hydrogen and oxygen atoms. The hydrogen atoms are then used to reduce carbon dioxide into glucose, while the oxygen atoms are released into the atmosphere.
Importance of Photosynthesis for Life on Earth
Photosynthesis is the primary source of food for all living organisms on Earth. It also produces oxygen, which is essential for respiration. Without photosynthesis, life on Earth would not be possible.
Cellular Respiration
Cellular respiration is the process by which cells use oxygen to break down glucose and produce energy. The process takes place in the mitochondria of cells and is essential for life on Earth.
Role of Mitochondria in Cellular Respiration
Mitochondria are organelles that are responsible for cellular respiration. They contain enzymes that break down glucose and produce energy in the form of ATP. ATP is the primary energy currency of cells and is used to power all cellular activities.
Importance of Cellular Respiration for Life on Earth
Cellular respiration is essential for life on Earth because it provides the energy that cells need to function. Without cellular respiration, cells would not be able to carry out their essential activities and life would not be possible.
Comparison of Photosynthesis and Cellular Respiration
| Photosynthesis | Cellular Respiration | |
|---|---|---|
| Reactants | Carbon dioxide, water, light energy | Glucose, oxygen |
| Products | Glucose, oxygen | Carbon dioxide, water, ATP |
| Energy Change | Endergonic (requires energy) | Exergonic (releases energy) |
Photosynthesis and cellular respiration are two essential processes for life on Earth. Photosynthesis provides the food and oxygen that cells need to survive, while cellular respiration provides the energy that cells need to function.

Questions and Answers
What is the primary role of chlorophyll in photosynthesis?
Chlorophyll absorbs sunlight, providing the energy necessary for converting carbon dioxide and water into glucose.
How does cellular respiration differ from fermentation?
Cellular respiration utilizes oxygen to break down glucose, releasing a significantly greater amount of energy compared to fermentation, which occurs in the absence of oxygen.
