Photosynthesis and Plant Growth

Front

Photosynthesis

Back

The process by which plants use light energy to make food in the form of carbohydrates.

Front

Chlorophyll

Back

A green pigment in the leaves that captures energy from the sun for photosynthesis.

Front

Stomata

Back

Tiny holes in plant leaves through which plants breathe in carbon dioxide and release oxygen.

Front

Chloroplasts

Back

Organelles where photosynthesis takes place, containing chlorophyll and grana.

Front

Photosynthesis Equation

Back

Sunlight + 6H2O + 6CO2 → C6H12O6 + 6O2; the process where water and carbon dioxide produce glucose and oxygen.

Front

Major Factors Affecting Photosynthesis

Back

Light intensity, temperature, carbon dioxide concentration, water availability, nutrients, pH balance, and oxygen presence.

Front

Wavelength of Light

Back

The spectrum of visible light required for plant growth, affecting photosynthesis.

Front

Commercial Plant Propagation

Back

Techniques like greenhouse placement, spacing, artificial watering, nutrient provision, temperature regulation, and CO2 level adjustment to maximize plant growth.

Front

Photosynthesis Process

Back

1. Light hits leaves. 2. Chloroplasts split water. 3. Carbon dioxide enters through stomata, combines in chloroplasts to make glucose. 4. Glucose is used for various plant functions.
