Photosynthesis (1.1):
Energy Source: Plants obtain energy from light and convert this energy into food.
Food Chain: Starts with plants as the primary source.
Process: 'Photosynthesis' means 'making with light'.
Diagram of Food Chain:
Grass → Cricket → Spider → Small Bird → Hawk
Page 9
Photosynthesis Essentials:
Requirements: Developed by plants using water, light, and carbon dioxide.
Outputs: Food (glucose) and oxygen.
Biomass: Newly formed living mass in plants.
Activity Involvement:
Suggested activity to observe the impact of light on plant growth.
Page 10
Leaves (1.2):
Main Function: Photosynthesis mainly occurs in leaves.
Chlorophyll: Green pigment essential for capturing light energy.
Leaf Structure:
Composition: Thin, so light penetrates effectively. Contains veins for water transport.
Page 11
Inside a Leaf:
Adaptations: Various internal structures support the photosynthesis process.
Stomata: Small openings that allow gas exchange (CO2 and O2).
Activities:
Experiment suggestion to observe stomata influence on gas exchange.
Page 12
Investigating Photosynthesis (1.3):
Gas Collection Experiment: To determine if a leaf is photosynthesizing by measuring oxygen output.
Activity Example:
Steps provided for setting up a gas collection experiment.
Page 13
Rate of Photosynthesis Investigation:
Plan to understand impact of light intensity on photosynthesis rate.
Conclusions:
Importance of result comparisons with predictions.
Page 14
Roots (1.4):
Functions of Roots: Absorb water and minerals, anchor the plant, and store food.
Activity Suggestion: Investigation involving food storage in root vegetables.
Page 15
