Whether the culprit were too much sunlight or not enough, if photosynthesis stopped, plants would stop converting carbon dioxide — an air pollutant — to organic material. Right now, we rely on photosynthetic plants, algae and even bacteria to recycle our air.

Why does the rate of photosynthesis decrease?

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.

What does the rate of photosynthesis mean?

The Rate of Photosynthesis Chlorophyll concentration – High chlorophyll concentration gives a high rate of photosynthesis. Carbon dioxide concentration – Increasing the carbon dioxide concentration increases the rate of photosynthesis because carbon dioxide is a reactant in photosynthesis.

Which would lead to a lower rate of photosynthesis?

Answer: Option D. Explanation: Photosynthesis is the process whereby green plants use light energy from sun with carbon dioxide and water to produce glucose and oxygen. A decrease in carbon dioxide in the atmosphere will reduce the rate of photosynthesis.

What increases the rate of photosynthesis?

Light intensity Without enough light, a plant cannot photosynthesise very quickly – even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor – a limiting factor – becomes in short supply.

What temperature is best for photosynthesis?

The optimum temperature range for photosynthesis is 35–40ºC.

What are 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 are the 5 factors that affect the rate of photosynthesis?

Several factors can affect the rate of photosynthesis:

• light intensity.
• carbon dioxide concentration.
• temperature.

  How does the level of light affect the rate of photosynthesis?

  Photosynthesis needs water, carbon dioxide, chlorophyll, light, and the right temperature. Light is an extremely important factor for the process. If there is enough water, carbon dioxide, and the temperature is right, light becomes the factor which will affect photosynthesis.

  What are the different methods of measuring the rate of photosynthesis?

  What are the different methods of measuring the rate of photosynthesis? There are a few key methods to calculate the rate of photosynthesis. These include: 1) Measuring the uptake of CO 2. 2) Measuring the production of O 2. 3) Measuring the production of carbohydrates. 4) Measuring the increase in dry mass

  Why is temperature a limiting factor in photosynthesis?

  On a hot day, photosynthesis happens at a higher rate when compared to the cooler day, showing that temperature has an effect and is the limiting factor on a cooler day. An increased level of carbon dioxide leads to a higher rate of photosynthesis when compared to the lower carbon dioxide level.

  How is photosynthesis different from aerobic respiration?

  Aerobic respiration continues all the time in plant cells (in light and in darkness), using up oxygen and making carbon dioxide. Photosynthesis, in contrast, occurs only in light and uses up carbon dioxide and makes oxygen. The more light there is, the more oxygen is produced.
