The sun is the main source of energy for most living things
Stages of photosynthesis:
Plants and other organisms use energy from the sun to convert carbon dioxide and water into oxygen and sugar/glucose
- Stage 1: Chloroplasts in plant cells capture energy from sunlight
- Stage 2 - The captured light energy is used to produce sugars and oxygen from water and carbon dioxide
- Carbon dioxide enters through the stomata
- Water enters through the roots
- Sugars are used by plant cells for energy
- Oxygen exits through the stomata
- Chlorophyll is the pigment that conducts photosynthesis
- Chloroplast is the organelle that conducts photosynthesis
Stages of cellular respiration:
Cells break down simple food molecules and release the energy they contain
Stage 1: In the cytoplasm, glucose is broken down into smaller molecules while small amount of energy is released
Stage 2: In the mitochondria, the smaller molecules combine with oxygen to produce water and carbon dioxide while large amounts of energy are released
Mitochondria is the organelle conducting cellular respiration
