Key Stage 3 Science (Biology) - Photosynthesis
The Science Break・6 minutes read
Photosynthesis is the process by which plants and algae produce food using light energy, with water and carbon dioxide as essential ingredients, resulting in the production of oxygen and glucose. The glucose produced is used for energy, stored as starch, and for plant tissue growth, forming the basis of food chains where plants are primary producers essential for sustaining animal life.
Insights
- Photosynthesis is the process by which plants and algae create food using light energy, necessitating water, carbon dioxide, sunlight, and chlorophyll to produce glucose and oxygen.
- Glucose generated through photosynthesis serves as an energy source, is stored as starch, and contributes to plant tissue growth, establishing plants as primary producers in food chains where animals depend on them for sustenance.
