Name the factors affecting Photosynthesis

Answer – Photosynthesis, the process by which plants convert light energy into chemical energy, is influenced by several factors. Optimising these factors can improve plant growth and maximise photosynthetic productivity.

Factors Affecting Photosynthesis

Light Intensity

Higher light intensities generally increase the rate of photosynthesis and ensure efficient energy conversion.

Carbon Dioxide Concentration

Adequate CO2 levels are essential for efficient photosynthesis, although there are saturation points where further increases will not increase the rate.

Temperature

Optimal temperatures support maximum photosynthetic activity, while extreme temperatures can denature enzymes and reduce rates.

Water Availability

Adequate water is critical to maintaining photosynthetic rates, as water scarcity limits carbon dioxide uptake and reduces efficiency.

Chlorophyll Levels

Nutrient deficiencies can lead to chlorophyll loss, reducing the plant’s ability to efficiently capture solar energy.

Protoplasm Balance

Maintaining adequate water and carbohydrate content in the protoplasm ensures optimal photosynthetic activity.

Leaf Structure

An optimal leaf structure with appropriate thickness, stomatal distribution and size allows efficient light absorption and gas exchange.
