Environmental factors include temperature, food, pollutants, population density, sound, light, and parasites. The diversity of environmental stresses that have been shown to cause an increase in asymmetry is probably not exclusive; many other kinds of stress might provide similar effects.

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.
• Temperature.

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.

Light and rate of photosynthesis Light dependent reactions use light energy and so are not affected by changes in temperature. As light intensity is increased further, however, the rate of photosynthesis is eventually limited by some other factor.

“Three factors can limit the speed 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.

The rate of photosynthesis should decrease and therefore the amount of oxygen bubbles should decrease. At the highest light intensities it is possible that the number of bubbles will plateau, as photosynthesis can be limited by several factors: light intensity, temperature, and carbon dioxide concentration.

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.

There are several factors that affect the rate of photosynthesis. Light intensity, water, soil pH, carbon dioxide concentration, temperature and other climatic conditions are the main factors affecting the rate of photosynthesis.

Water stress causes closure of stomata and decreases the availability of ${{CO}_{2}}$ for photosynthesis. Water stress also causes wilting of leaves, thus reducing the surface area of leaves for metabolic functions.

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

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. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.

Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. The sugars are used by the cell as energy, and to build other kinds of molecules.

• Step 1-Light Dependent. CO2 and H2O enter the leaf.
• Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.
• Step 3- Light Dependent. The electrons move down to enzymes.
• Step 4-Light Dependent.
• Step 5-Light independent.
• Step 6-Light independent.
• calvin cycle.

Reasons Why Photosynthesis Is Important It is the number one source of oxygen in the atmosphere. It contributes to the carbon cycle between the earth, the oceans, plants and animals. It contributes to the symbiotic relationship between plants, humans and animals. It directly or indirectly affects most life on Earth.

How Light-Dependent Reactions Work. The overall function of light-dependent reactions, the first stage of photosynthesis, is to convert solar energy into chemical energy in the form of NADPH and ATP, which are used in light-independent reactions and fuel the assembly of sugar molecules.
