What is the unit for light intensity? Explain the difference between shade-loving and sun-loving plants according to the graph. Define the term light compensation point.
Understand the Problem
The question involves understanding the relationship between light intensity and photosynthesis in plants, specifically the differences between sun-loving and shade-loving plants. Tasks include understanding units, differences in growth conditions, and concepts related to photosynthesis.
Answer
Lux or μmol photons/m²/s. Sun-loving plants have higher compensation points. Light compensation point: photosynthesis rate equals respiration rate.
The unit for light intensity is lux or μmol photons/m²/s. Sun-loving plants have higher light compensation points and can photosynthesize at higher light intensities compared to shade-loving plants. The light compensation point is where the rate of photosynthesis equals the rate of respiration.
Answer for screen readers
The unit for light intensity is lux or μmol photons/m²/s. Sun-loving plants have higher light compensation points and can photosynthesize at higher light intensities compared to shade-loving plants. The light compensation point is where the rate of photosynthesis equals the rate of respiration.
More Information
Shade-loving plants can thrive under lower light conditions due to their lower light compensation points. This enables them to effectively photosynthesize at light levels that are too low for sun-loving plants.
Tips
Confusing the light saturation point with the light compensation point. Remember, the compensation point is where photosynthesis equals respiration.
