However, photosynthesis and cellular respiration are two processes that both involve electron transport chains and they both affect concentrations of carbon dioxide and oxygen in the atmosphere. Both photosynthesis and cellular respiration provide energy to the organism's cells.

As light intensity increases (distance between lamp and plant decreases) the volume of oxygen (or the rate of bubble production) increases. This indicates that the rate of photosynthesis increases with light intensity. However, at sufficiently high levels of light intensity, the rate oxygen evolution remains constant.

Photosynthesis uses water and carbon dioxide, and it makes glucose and oxygen. Cellular respiration uses glucose and oxygen, and it makes water and carbon dioxide.

Photosynthesis is a natural process by which trees and plants use energy from the sun and carbon dioxide from the air to make the food they need to live and grow. By storing carbon above and below the ground, the trees and plants in forests contribute to the production of oxygen as a byproduct of photosynthesis.

Under elevated CO2 most plant species show higher rates of photosynthesis, increased growth, decreased water use and lowered tissue concentrations of nitrogen and protein. Rising CO2 over the next century is likely to affect both agricultural production and food quality.

To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.

Photosynthesis. ... 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.

Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into sugars. ... Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions.

Sunlight provides the energy needed for photosynthesis to take place. In this process carbon dioxide and water are converted into oxygen (a waste product that is released back into the air) and glucose (the source of energy for the plant).

Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.

The rate of photosynthesis is directly proportional to the light intensity until another factor becomes limiting. At very high light intensities, photosynthesis is slowed, but these light intensities do not occur in nature.

Answer and Explanation: Photosynthesis in involved in the water cycle because it facilitates transpiration and uses water as a reactant. During photosynthesis, plants use water, sunlight and carbon dioxide to make oxygen and glucose. The water is obtained from the ground and is taken into the plants through the roots.

Increasing photosynthesis increases carbon availability for plants. Whether, or to what extent, that translates into increased growth depends on the nature of colimiting factors, especially nutrient availability. Any increase in carbon availability will exacerbate nutrient limitations.

The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun's energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water.

Photosynthesis takes in the carbon dioxide produced by all breathing organisms and reintroduces oxygen into the atmosphere. Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight and turn it into chemical energy.

Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply. The rate of photosynthesis is directly proportional to the light intensity until another factor becomes limiting.
