We learned that light intensity, carbon dioxide concentration, and temperature are the three main factors that impact photosynthesis. Greater light intensity leads to higher photosynthesis rates, as does increased carbon dioxide concentration.

Simply so, what are the 4 factors that affect photosynthesis?

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

Also, what factors affect the rate of photosynthesis quizlet? Temperature, light intensity, carbon dioxide levels, water, oxygen and chlorophyll. The rate of photosynthesis increases as the temperature increases.

Keeping this in view, what are the five factors that affect photosynthesis?

Several factors can affect the rate of photosynthesis: light intensity. carbon dioxide concentration. temperature.

Factors affecting photosynthesis

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

What is photosynthesis and what factors affect it?

We learned that light intensity, carbon dioxide concentration, and temperature are the three main factors that impact photosynthesis. Greater light intensity leads to higher photosynthesis rates, as does increased carbon dioxide concentration.

Why is photosynthesis important?

Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy.

Does heat speed up photosynthesis?

as the temperature increases, the enzymes get more energy so the rate of photosynthesis increases. If it gets too hot the enzymes begin to lose their shape (denature). this means they are unable to function properly and the rate of photosynthesis decreases again.

What is the equation for photosynthesis?

The Photosynthesis Equation. The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.

Does heat affect photosynthesis?


The higher the temperature then typically the greater the rate of photosynthesis, photosynthesis is a chemical reaction and the rate of most chemical reactions increases with temperature. However, for photosynthesis at temperatures above 40°C the rate slows down.

What are the byproducts of photosynthesis?

During the process of photosynthesis, we obtain, C6H12O6 (glucose) as the main product and oxygen as the byproduct. This process has two reactions: light reaction and dark reaction. hydrogen, protons, electrons, assimilatory powers(ATP and NADPH) are produced and oxygen is evolved.

What sugar is formed in photosynthesis?

Plants convert energy from sunlight into sugar in a process called photosynthesis. Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen (Figure 2).

How does too much light affect photosynthesis?

The process of photosynthesis requires three things: Light, Carbon dioxide and water. If any one of these things is in short supply, then photosynthesis cannot happen. But, if you have too much light, than the other 2 ingredients become limiting and photosynthesis can no longer increase with the level of light.

What can stop photosynthesis?

Photosynthesis is the process by which plants absorb sunlight and use it to transform carbon dioxide and water into glucose and oxygen. The major limiting factors in this process are light intensity, temperature, and carbon dioxide levels.

What is the maximum rate of photosynthesis?


Photosynthetic capacity (Amax) is a measure of the maximum rate at which leaves are able to fix carbon during photosynthesis. It is typically measured as the amount of carbon dioxide that is fixed per metre squared per second, for example as μmol m2 sec1.

What are the two stages of photosynthesis?

The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.

What affects the rate of respiration?

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 do you mean by photosynthesis?

photosynthesis. Plants absorb sunlight and turn that energy into food; the process is known as photosynthesis. This is a compound word made up of photo (which means "light") and synthesis (which means "to put together"). A plant uses light to put together chemical compounds and turn them into carbohydrates: food.

How water affects the rate of photosynthesis?

The amount of water available to the plant will affect the rate of photosynthesis. If the plant does not have enough water, the plant's stomata will shut and the plant will be deprived of CO². Carbon dioxide concentration will directly affect the rate of photosynthesis as it is used in the photosynthesis reaction.

How does photosynthesis help the environment?


In photosynthesis, plants constantly absorb and release atmospheric gases in a way that creates sugar for food. Carbon dioxide goes in the plant's cells; oxygen comes out. Without sunlight and plants, the Earth would become an inhospitable place unable to support air-breathing animals and people.

Where does photosynthesis occur?

Photosynthesis takes place inside plant cells in small things called chloroplasts. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll. Below are the other parts of the cell that work with the chloroplast to make photosynthesis happen.

What external factors affect photosynthesis?

Many external and internal factors affect the rate of photosynthesis. The external or environmental factors at:A light intensity, carbon dioxide concentration and temperature. The internal factor influencing the photosynthesis is chlorophyll content of the leaves and protoplasmic factors.
