The main variables which affect photosynthesis are light, water, CO2 concentration and temperature.
What are the 4 abiotic factors a plant needs to do photosynthesis?
The most important abiotic factors for plants are light, carbon dioxide, water, temperature, nutrients, and salinity.
What are the 4 factors that affect photosynthesis?
Photosynthesis is affected by light, temperature, water, and CO2. Stomata affect the process of transpiration and do not affect photosynthesis.
What are 4 abiotic factors?
The most important abiotic factors include water, sunlight, oxygen, soil and temperature.
What is the abiotic factor influencing photosynthesis?
The rate of photosynthesis in a plant can be determined by three external factors: temperature, light intensity, and available carbon dioxide concentration. In any given situation any one of these may become a limiting factor if they are below the optimal level (Alott and Mindorff).
What are the 7 abiotic factors?
In biology, abiotic factors can include water, light, radiation, temperature, humidity, atmosphere, acidity, and soil.
What biotic factors affect 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. …
What are the 5 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. 1. Effect of Carbon dioxide: Being one of the raw materials, carbon dioxide concentration has great effect on the rate of photosynthesis.
What factors affect 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 factors affect photosynthesis and cellular respiration?
It’s the process by which green, chlorophyll-containing plants create food from sunlight, carbon dioxide, and water. Photosynthesis is the reason that the sun’s energy is able to spark life on Earth. Plants gain the sun’s energy, and those plants are then eaten by animals.
What are the 6 abiotic factors?
Examples of Abiotic Factors
For instance, abiotic components in a terrestrial ecosystem include air, weather, water, temperature, humidity, altitude, the pH level of soil, type of soil and more.
What are 5 abiotic factors in grasslands?
All these abiotic factors greatly affect the grassland ecosystem.
- Soil. The soil of this ecosystem is very fertile as it contains carbon, nitrogen, oxygen, phosphorus, etc. …
- Temperature. …
- Rainfall. …
What are the types of abiotic factors?
Types of Abiotic Factors
- Temperature and Light. The temperature of the air and the water affect the animals, plants, and humans in nature. …
- Water. All living organisms need some intake of water. …
- Atmosphere. The atmosphere sustains life on earth. …
- Chemical Elements. …
