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 three abiotic factors affect photosynthesis?
Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.
What are 4 main abiotic factors that affect photosynthesis?
The main variables which affect photosynthesis are light, water, CO2 concentration and temperature.
How do abiotic factors affect the rate of photosynthesis?
Abiotic factors include: Light intensity: limited light will limit photosynthesis. This will affect the distribution of plants, and therefore the distribution of animals that eat plants. … Temperature: temperature is a limiting factor for photosynthesis – and low temperature therefore limits growth of plants.
What are three biotic factors?
Biotic factors have been divided into three main categories, which define their distinctive role in the ecosystem:
- Producers (Autotrophs)
- Consumers (heterotrophs)
- Decomposers (detritivores)
What are five factors that affect the rate of 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 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 factors affect the rate of cellular respiration?
We’ll first review what cellular respiration is, and then explore how three factors affect it: temperature, glucose availability, and oxygen concentration.
What factors affect the rate of photosynthesis in living leaves?
The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
What are the 5 abiotic factors?
The most important abiotic factors for plants are light, carbon dioxide, water, temperature, nutrients, and salinity.
What factor will increase the rate of photosynthesis?
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.
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.
How biotic factors affect abiotic factors?
A biotic factor is a living thing that has an impact on another population of living things or on the environment. Abiotic factors do the same thing, but they are non-living. … To survive, biotic factors need abiotic factors. In turn, biotic factors can limit the kinds and amounts of biotic factors in an ecosystem.
What does not affect the rate of photosynthesis?
Photosynthesis is affected by light, temperature, water, and CO2. Stomata affect the process of transpiration and do not affect photosynthesis.
What abiotic factors affect the rate of photosynthesis in pondweed?
Photosynthesis in plants is affected by a number of abiotic factors, for example light intensity, temperature and light wavelength. Species of pondweed contain specialised tissue (aerenchyma) that allows gases to diffuse inside the plant.
