Q1: Define nutrition. Name the two types of nutrition.
Nutrition is the process by which organisms obtain food and use it to grow, produce energy, and repair body tissues.
Two types of nutrition:
1. Autotrophic nutrition - organisms make their own food (e.g., plants, green algae)
2. Heterotrophic nutrition - organisms obtain food from other organisms (...
Q2: Write the balanced chemical equation for photosynthesis.
6CO2 + 6H2O → C6H12O6 + 6O2
(in the presence of light energy and chlorophyll)
Or in word form:
Carbon dioxide + Water → Glucose + Oxygen
(light is needed for this reaction)
Q3: What are the raw materials and products of photosynthesis? Where do they come from and where do they go?
Raw materials of photosynthesis:
1. Carbon dioxide (CO2) - enters through stomata in leaves
2. Water (H2O) - absorbed by roots from soil
3. Light energy - from the Sun
Products of photosynthesis:
1. Glucose (C6H12O6) - stored as starch in leaves and used for growth and energy
2. Oxygen (O2) - relea...
