What factors affect the rate of respiration in plants?

Factors Influencing Respiratory Rate:

• Type and Age of Plant Tissue.
• State of Respiring Protoplasm.
• Temperature.
• Hydration of Tissues.
• Light.
• Oxygen.
• Carbon Dioxide.
• Inorganic Salts.

What are 3 factors that affect respiration?

Chemical- carbon dioxide, hydrogen ions and oxygen levels are the most important factors that regulate respiration.

What are the 5 factors affecting respiration?

Factors affecting respiration

• The process of respiration is influenced by a number of external and internal factors.
• The main external factors are temperature, light, oxygen supply, water supply, CO2​ concentration, toxic and stimulating substances and disease and injury.

What factors affect the rate of photosynthesis and respiration?

Several factors can affect the rate of photosynthesis:

• light intensity.
• carbon dioxide concentration.
• temperature.

What are the factors affecting the rate of 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.

What factors affect respiration rate in yeast?

The rate of respiration is influenced by different ​factors​(e.g. temperature, pH, nutrient availability). The effect of each of these factors can be determined by changing ​one variable only​, and observing its effect on the rate of reaction.

What is the rate of respiration in plants?

Annually, terrestrial plant respiration releases 40–60 \% of the total carbon fixed during photosynthesis (Gifford, 1994; Amthor, 1995) representing about half of the annual input of CO2 to the atmosphere from terrestrial ecosystems (Schlesinger, 1997).

What factors are most likely to affect the breathing rate?

The rate of breathing is affected by many chemical factors like the level of carbon dioxide and oxygen in the blood. The increase in levels of the carbon dioxide will lower the blood pH this will direct the medulla of the brain to increase the breathing rate to obtain more amount of oxygen in the body.

What factors affect photosynthesis rate?

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

What are five factors that could affect the rate of photosynthesis?

The environmental factors which can affect the rate of photosynthesis are carbon dioxide, light, temperature, water, oxygen, minerals, pollutants and inhibitors. 1. Effect of Carbon dioxide: Being one of the raw materials, carbon dioxide concentration has great effect on the rate of photosynthesis.

What are the 4 factors that affect photosynthesis?

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

What are four factors that affect photosynthesis?

What factor most affects the rate of photosynthesis? The main variables which affect photosynthesis are light, water, CO2 concentration and temperature.

What are the factors that affect 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 is respiration in plants?

Respiration converts oxygen and the sugars generated during photosynthesis into carbon dioxide, water and energy. In addition to the type of plant, several environmental factors affect a plant cell’s rate of respiration. Plants “breathe” as part of the growth cycle.

What factors affect the amount of respirable material in a plant?

Secondly, the quantity of respirable material in the plant largely depends upon the rate of photosynthesis which is directly influenced by light and thirdly, stomata remain open during daylight and hence rapid exchange of gases takes place through them.

How does water affect cellular respiration?

Besides nutritional factors affecting cellular respiration in plants and animals, water also influences the process. For example, water in dry seeds is always responsible for low rates of respiration in cells. In addition, in wilted tissues, starch is transformed into sugars, making it available to allow the process of respiration to occur.
