What are the 6 factors that affect photosynthesis?
The environmental factors which can affect the rate of photosynthesis are carbon dioxide, light, temperature, water, oxygen, minerals, pollutants and inhibitors.
What are the factors that affect respiration in plants?
The eight environmental factors effecting the rate of respiration are: (1) Oxygen Content of the Atmosphere (2) Effect of Temperature (3) Effect of Light (4) Effect of Water Contents (5) Effect of Respirable Material (6) Effect of Carbon Dioxide Concentration (7) Protoplasmic Conditions and (8) Other Factors.
What factors might affect cellular respiration rate?
We’ll first review what cellular respiration is, and then explore how three factors affect it: temperature, glucose availability, and oxygen concentration.
What are 3 factors that affect the rate of 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.
What are the factors that affect the rate of photosynthesis which is considered the most important?
The amount of light, the carbon dioxide supply, temperature, water supply, and the availability of minerals are the most important environmental factors that affect the rate of photosynthesis in land plants.
What are factors affecting respiration?
Factors affecting respiration
- The process of respiration is influenced by a number of external and internal factors.
- The main external factors are temperature, light, oxygen supply, water supply, CO2 concentration, toxic and stimulating substances and disease and injury.
What factors affect photosynthesis rate?
Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.
What internal factors affect respiration?
The main external factors are temperature, light, oxygen supply, water supply, CO2 concentration, toxic and stimulating substances and disease and injury. The internal factors include the amount of respirable material and respiratory enzymes, acidity of the cell sap and activity of the organism.
What factors affect photosynthesis?
The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
What factors affect the rate of respiration in humans?
Chemical- carbon dioxide, hydrogen ions and oxygen levels are the most important factors that regulate respiration. chemoreceptors- sensory receptors that detect CO2, H, and O2 levels in the blood.
Which factors are necessary for photosynthesis to occur?
There are many factors which are necessary for photosynthesis. These factors are light, chlorophyll, carbon dioxide, water, and temperature . Light is a very important factor for the process of photosynthesis as it generates the energy required during the process and build chlorophyll.
How does temperature affect photosynthesis?
When the temperature rises, the particles in the reaction move quicker and collide more, so the rate of photosynthesis rises also. At the optimum temperature, the enzyme is most efficient and the rate if maximum. At temperatures above 40°C the rate slows down.
What are the factors affecting transpiration?
The factors affecting the transpiration include. Light. Temperature. Wind velocity. Atmospheric humidity. Atmospheric pressure. Available water.
What is the role of light intensity in photosynthesis?
Light supplies the energy for the process and varies in intensity, quality and duration. When CO2 and temperature are not limiting and light intensities are low, the rate of photosynthesis increases with an increase in its intensity.
