What are the factor affecting respiration in plants?

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.

How does water supply affect respiration in plants?

Respiration rates affected by a decrease in water content. It means that a decrease in water content caused a decrease in oxygen consumption and respiration rates (Brix, 1962; Crafts, 1968). The decrease of water content in 704 plants was higher than 301 plants and in roots was higher than shoots.

How does respiration affect photosynthesis?

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.

How does photosynthesis and respiration affect plant growth?

The glucose formed during photosynthesis provides energy to the plants. The process of respiration makes effective use of energy. In this process, oxygen is given off by the plants to the surroundings. The carbon dioxide is taken up from the surroundings in used in photosynthesis.

What are 3 factors that affect respiration?

A number of factors can influence the respiration rate, such as: Age – younger children generally have higher oxygen demands and therefore breath faster. Pain – pain will cause an increase in respiration rate. Emotion – emotion will cause an increase in respiration rate.

What are factors affecting photosynthesis?

Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.

What can affect the rate of respiration?

Rate of respiration depends on several factors such as temperature, oxygen, carbon dioxide, salts, water, hormones, light, inhibitors, age, injury/disease, etc. Increase in temperature increases the rate of respiration. Rate of respiration increases with increase in oxygen concentration.

What factors affect the rate of photosynthesis?

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

What is difference between photosynthesis and respiration?

Photosynthesis is the process of production of glucose in the presence of carbon dioxide and water. Respiration is the process of production of carbon dioxide and water due to breaking down of carbohydrates.

What are the factors which affect photosynthesis?

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.

How do you increase respiration in plants?

A high day temperature can increase photosynthesis, especially when light and CO2 are not limiting. However, respiration also increases with temperature because plants need more energy to support the increased rate of cell division and expansion.

What are the factors that control respiration?

Solution : Oxygen and temperature are the two important factors that control the process of respiration.

What are the 4 limiting factors of photosynthesis?

Factors That Limit the Rate of Photosynthesis

  • The presence of photosynthetic pigments.
  • A supply of carbon dioxide.
  • A supply of water.
  • Light energy.
  • A suitable temperature.

Which of these will not affect photosynthesis?

The absence of oxygen will have no effect on the process of photosynthesis.

What are 5 factors that affect photosynthesis?

External factors that influence photosynthetic rate: temperature, pH levels in the soil, the intensity of the light, weather conditions, and concentration of carbon dioxide.

Which factor does not affect the rate of photosynthesis?


Photosynthesis is affected by light, temperature, water, and CO2. Stomata affect the process of transpiration and do not affect photosynthesis.

What do cell respiration and photosynthesis have in common?

Photosynthesis and cellular respiration are two biochemical processes that are essential to most life on Earth. Both of these processes involve multiple complex steps and many of the same molecules—oxygen (O2), carbon dioxide (CO2), water (H2O), glucose (C6H12O6), and adenosine triphosphate (ATP).

How do you differentiate basic features of photosynthesis and respiration?

The principal difference, however, between photosynthesis and respiration is that photosynthesis utilizes carbon dioxide and water in the presence of light to produce glucose and oxygen, whereas respiration uses oxygen and glucose to power the activities of the cell.

What factors affect rate of respiration?

What stops photosynthesis?

What affects rate of photosynthesis?

What factors can affect photosynthesis?

What are the 6 factors that affect photosynthesis?

Answer: The chlorophyll content of leaves, the accumulation of by-products, the internal structure of leaves, light intensity, carbon dioxide concentration, and temperature are the six factors influencing the rate of photosynthesis.

What are the 3 most important factors that affect photosynthesis?

What can affect the rate of photosynthesis?
