What are the environmental factors affecting 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 environmental factor could affect the rate of photosynthesis in a plant?

The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.

What are the three environmental factors that affect a plant’s growth?

The three most ecologically important environmental factors affecting rangeland plant growth are light, temperature, and water (precipitation). Plant growth and development are controlled by internal regulators that are modified according to environmental conditions.

What are 3 factors needed for photosynthesis?

To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant’s leaves, flowers, branches, stems, and roots. Plants also require water to make their food.

What are four environmental factors that affect transpiration?

Rate of transpiration

• temperature.
• humidity.
• wind speed.
• light intensity.

What are the factors that affect photosynthesis Class 7?

Factors affecting photosynthesis

• the rate of oxygen output.
• the rate of carbon dioxide uptake.
• the rate of carbohydrate (glucose) production.

How does environmental factors affect transpiration rate?

Transpiration is affected greatly by the environment factors such as temperature, light relative humidity, wind, and so on. Transpiration increases with increasing air temperature and wind velocity. At constant temperature and wind velocity, transpiration rate is governed by moisture content of air.

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.
