Study Notes
Photosynthesis
- Photosynthesis occurs primarily in chloroplasts, organelles responsible for capturing sunlight.
- Necessary reactants for photosynthesis include sunlight, water (H2O), and carbon dioxide (CO2).
- Photosynthesis produces glucose (C6H12O6) and oxygen (O2) as key products.
- The process is vital for converting solar energy into chemical energy stored in glucose.
Cellular Respiration
- Cellular respiration takes place in mitochondria, which are known as the powerhouse of the cell.
- Key reactants required for cellular respiration are glucose (C6H12O6) and oxygen (O2).
- The process yields energy, carbon dioxide (CO2), and water (H2O) as products.
- Cellular respiration is essential for organisms to extract energy from nutrients.
Interconnection of Photosynthesis and Respiration
- Both processes recycle four vital substances: oxygen (O2), carbon dioxide (CO2), water (H2O), and glucose (C6H12O6).
- Sunlight is a crucial component for photosynthesis that cannot be recycled; it must continually be available.
Presence of Organelles in Cells
- Chloroplasts are predominantly present in plant cells, facilitating the photosynthesis process necessary for plant survival.
- Mitochondria are found in both plant and animal cells, enabling cellular respiration needed for energy production.
- Animal cells lack chloroplasts as they do not perform photosynthesis, whereas they heavily rely on mitochondria for energy through cellular respiration.
