Plant Growth, Seeds & Photosynthesis Foundations
Investigate how seeds sprout, roots take in water, and leaves convert sunlight into chemical energy.
Why It Matters:Vital for agricultural sustainability, global food security, and environmental conservation.

Worked Example
Explain what happens during seed germination and early shoot development:
1
Water absorption (imbibition)
Seed coat softens + embryo swells
Water activates enzymes inside the dormant seed.
2
Root emergence (radicle)
Radicle grows downward with gravity
Anchors the seedling and draws minerals from soil.
3
Shoot and leaf expansion
Shoot rises toward sunlight + chlorophyll initiates
Leaves produce glucose via sunlight.
✓Verification Check
Verify: Without water and sunlight, germination and growth halt.
Inputs: Water + Light + CO2
•
Outputs: Glucose + O2
⚠️ Common Pitfalls & Misconceptions
Believing plants eat soil for food
✗ Claiming plants consume soil particles through roots✓ Plants absorb minerals and water from soil, but synthesize their own food (glucose) from sunlight and air
Plants are autotrophs; soil provides nutrients, not caloric food.
