The Science of Photosynthesis: How Plants Make Energy
Understand the fascinating process that powers all plant life.
What is Photosynthesis?
Plants convert light energy, water, and CO2 into glucose (food) and oxygen.
The Process
Chlorophyll in leaves absorbs light, primarily red and blue wavelengths. This energy splits water molecules, releasing oxygen.
Light Reactions
Occur in chloroplasts, producing ATP and NADPH (energy carriers).
Calvin Cycle
Uses ATP and NADPH to convert CO2 into glucose.
Why This Matters for Care
Understanding photosynthesis explains why light quality, intensity, and duration affect plant growth.
Variegated Plants
Less chlorophyll means slower photosynthesis, requiring brighter light.
