Why do plants lose mass during cellular respiration?

What molecules are taken in by plant cells used to create molecules that become part of the plants biomass? ... This shrinks because there is only water so only cellular respiration takes place, which causes the plant to lose mass.

How does photosynthesis and respiration affect plant growth?

The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. As with photosynthesis, plants get oxygen from the air through the stomata. ...

Does increased photosynthesis increase respiration?

With no light, there is no photosynthesis. So the rate of respiration is greater than the rate of photosynthesis. So this means there is an overall excess of carbon dioxide produced during respiration. ... There will come a point when the rate of photosynthesis has increased to match the rate of respiration.

What causes plant respiration to increase?

Abstract. Background Elevated levels of atmospheric [CO₂] are likely to enhance photosynthesis and plant growth, which, in turn, should result in increased specific and whole-plant respiration rates.

What is the relationship between photosynthesis and cellular respiration?

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Does mass affect cellular respiration?

Aerobic respiration rate is the speed at which the cells of an organism convert oxygen into energy and release waste in the form of carbon dioxide. ... Our experiment yielded a negative correlation between the body mass and aerobic respiration of ectothermic milkweed bugs.

Why do plants need to do both photosynthesis and cellular respiration?

Just like animals can't live without cellular respiration, plants can't live without cellular respiration, either. Photosynthesis and respiration in plants are complementary processes because photosynthesis is only one half of the process of getting energy for a plant. It's how they make food, not how they consume it.

Why does aerobic respiration increase during exercise?

Aerobic respiration is simply breathing. When you exercise, your breathing rate increases to compensate for the increased need of oxygen that is required by your muscles. When you exhale, you expel carbon dioxide, the by-product of used oxygen.

How does photosynthesis cause plant growth?

Photosynthesis in the forest

Photosynthesis provides most of the oxygen that humans and animals breathe. ... Chlorophyll uses sunlight energy to transform the carbon dioxide and water into oxygen and carbon-based compounds such as glucose, a sugar that helps plants grow.

What factors affect the respiration rate of a plant?

For most plant species temperature, acidity, salt concentration and the amount of moisture, carbon dioxide and oxygen are some of the additional important factors which affect respiration.

Why does the rate of photosynthesis decrease at higher temperature?

The rate of photosynthesis decreases at higher temperatures because at high temperatures the enzymes become denatured (destroy).

Why does the rate of photosynthesis start to decrease as the temperature increases above optimum?

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.

Why plants have lower respiratory rates?

Carbon Dioxide Levels

The higher the concentration of carbon dioxide, the lower the rate of respiration. This can occur during times of reduced gas exchange in the atmosphere, such as when a plant is conserving water.

What happens during plant respiration?

The plants get energy through the process of respiration in which glucose food breaks down in the presence of oxygen to form carbon dioxide and water with the release of energy. ... In other words, in plants, each part can independently take in oxygen from air, utilize it to obtain energy, and give out carbon dioxide.

What do plants release during photosynthesis?

During photosynthesis, plants take in carbon dioxide (CO₂) and water (H₂O) from the air and soil. ... The plant then releases the oxygen back into the air, and stores energy within the glucose molecules. Chlorophyll. Inside the plant cell are small organelles called chloroplasts, which store the energy of sunlight.
