What affects the rate of photosynthesis answer key?
Three factors that affect the rate of photosynthesis are temperature, light intensity, and the availability of water. dioxide.
What affects the rate of photosynthesis worksheet?
Many things affect the rate (speed) at which photosynthesis occurs: the amount of light (light intensity), the temperature, and the amount of carbon dioxide are a few factors. Scientists know that temperature affects the speed of chemical reactions. Photosynthesis is a series of chemical reactions.
What are the factors affecting photosynthesis?
Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.
- Light intensity. Without enough light, a plant cannot photosynthesise very quickly – even if there is plenty of water and carbon dioxide.
- Carbon dioxide concentration.
- Temperature.
Which factor least influences the rate of photosynthesis?
The major limiting factors for photosynthesis are light intensity, temperature, and carbon dioxide levels.
- Light Intensity. Since photosynthesis cannot begin without light, it is the first limiting factor.
- Temperature.
- Carbon Dioxide Concentration.
What affects the rate of photosynthesis quizlet?
Temperature, light intensity, carbon dioxide levels, water, oxygen and chlorophyll. The rate of photosynthesis increases as the temperature increases. However, the rate declines after the temperature reaches an optimal level (usually around 35 C). The rate of photosynthesis increases as light intensity increases.
What are the factors that affect photosynthesis Class 7?
Light intensity, water, soil pH, carbon dioxide concentration, temperature and other climatic conditions are the main factors affecting the rate of photosynthesis.
How does limiting factors affect photosynthesis?
Any change in the level of a limiting factor will affect the rate of reaction. For example, the amount of light will affect the rate of photosynthesis. If carbon dioxide and light levels are high, but temperature is low, increasing temperature will have the greatest effect on reaching a higher rate of photosynthesis.
What are the factors affecting photosynthesis Brainly?
The principle factors which influence photosynthesis are light, water, CO2 fixation and temperature.
Which factor does not affect photosynthesis?
Photosynthesis is affected by light, temperature, water, and CO2. Stomata affect the process of transpiration and do not affect photosynthesis.
Which things affect the rate of photosynthesis?
light intensity
What are environmental factors directly influence photosynthesis?
Photosynthesis is influenced by both environmental and genetic factors. The environmental factors include light, availability of CO2, temperature, soil, water and nutrient supply apart from age of leaf, leaf angle and leaf orientation. Photosynthesis is not affected by all environmental factors at a given time.
How does temperature influence photosynthesis?
Temperature affects photosynthesis by allowing plants to photosynthesize (i.e., build up) and respire (i.e., break down) when there is optimum daytime temperature. It also enables plants to curtail the rate of respiration at a cooler night.
Does temperature affect the photosynthesis?
At temperatures above 68 degrees Fahrenheit, or 20 degrees Celsius, the rate of photosynthesis decreases because the enzymes do not work as efficiently at this temperature. This is despite the increase of carbon dioxide diffusion into leaves.
