Factors Affecting Photosynthesis
Limiting Factors
Light Intensity
Without enough light photosynthesis can't fully process.
The compensation point
Where light intensity is at the point where the rate of photosynthesis is equal to the rate of respiration.
Light intensities below / more respiration occurs
Higher light intensities below / more photosynthesis occurs
Limiting factor
A condition that, when in shortage, it slows down the rate of a reaction.
Carbon dioxide concentration
Carbon Dioxide and water combine to photosynthesis.
Temperature
Extreme temperatures affect enzyme activity.
Amount of Chlorophyll
Plants growing in darkened environments (produce chlorophyll) in order to absorb the necessary light.
Certain plant illnesses have an impact on chlorophyll levels, which affects a plant's capacity for photosynthesis.
Water Availability
Water shortage limits electrons and CO₂ uptake.
Leaf Surface Area
Larger leaves absorb more light and CO₂
Nutrient Availability
Essential nutrients boost photosynthesis.
key molecules and enzymes
RuBisCo
An enzyme that catalyzes the reaction between CO₂ and ribulose bisphosphate (RuBP) during the Calvin cycle.
Chlorophyll
The primary pigment that absorbs light energy.
Key terms
Leaf Morphology
Shape and structure influence light absorption.
Chlorophyll
The pigment that absorbs light energy.
Drought Stress
Water scarcity negatively impacts photosynthesis.
Stomata
Openings that regulate gas exchange.
CO₂ Uptake
The amount of CO₂ absorbed by the plant.
Soil Fertility
Nutrient-rich soil enhances plant growth and photosynthesis.
RuBisCo
Key enzyme in carbon fixation.
Optimal Temperature Range
Temperature range where photosynthesis is most efficient.
ATP
Energy carrier in photosynthesis.
