Which affects the rate photosynthesis the least?
The rate of photosynthesis increases as the temperature increases. However, the rate declines after the temperature reaches an optimal level (usually around 35 C). The rate of photosynthesis increases as light intensity increases. However, the rate will not increase beyond a certain level of light intensity.
What affects the rate of photosynthesis?
The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
What makes photosynthesis slower?
Carbon dioxide level – Photosynthesis can be limited by the level of carbon dioxide. Even if there is plenty of light a plant cannot photosynthesise if it has run out of carbon dioxide. 3. Temperature – If it gets too cold the rate of photosynthesis will slow right down.
Does light intensity affect the rate of photosynthesis?
As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis.
Which of the following will slow down photosynthesis quizlet?
Which of the following will slow down photosynthesis? Low carbon dioxide levels in the atmosphere.
What effects photosynthesis?
Photosynthesis converts light energy into usable chemical energy for plant growth and development (1). As the most intricate physiological process in plants, photosynthesis incorporates numerous components, including CO2 reduction pathways, photosynthetic photosystems and the electron transport system (2).
Which of the following has no effect on photosynthesis?
There are many factors that can alter the rate of photosynthesis. However, one that does not affect this process is Humidity. Studies are indicative of the fact that humidity plays almost negligible role in the process of photosynthesis. Therefore, option b, is the correct answer.
Which of the following will slow down photosynthesis?
Which of the following will slow down photosynthesis? Low carbon dioxide levels in the atmosphere.
Which among the factors has the greatest effect on the success of photosynthesis?
Greater light intensity leads to higher photosynthesis rates, as does increased carbon dioxide concentration. However, once light intensity and carbon dioxide concentration reach a certain level, photosynthesis rates level off and don't increase much further.
Does water affect the rate of photosynthesis?
Water affects the rate of photosynthesis indirectly. When the water supply is limited then stomatal closure affects the rate of photosynthesis. Water stress causes the stomata to close and thereby reduces carbon dioxide availability.
How does temperature affect the rate of photosynthesis?
The rate of photosynthesis is influenced by temperature. Higher the temperature, greater the rate of photosynthesis. This is because photosynthesis is a chemical reaction and most of the chemical reactions are accelerated with temperature.
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.
Which of the following is a plant factor that affect the rate of photosynthesis?
The external factors include the availability of sunlight, temperature, CO2 concentration and water. Light: It is an essential factor for photosynthesis.
Which of the following does not affect the rate of photosynthesis light intensity light quality duration of light carbon dioxide concentration?
Duration of light: Light duration does not affect the rate of photosynthesis, but it affects the overall photosynthesis.
How does light affect the rate of photosynthesis?
As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis.
What is limiting the rate of photosynthesis?
The main external factors that affect the rate of photosynthesis are: Light intensity. Carbon dioxide concentration. Temperature.
How light intensity affects the rate of photosynthesis?
As light intensity increases, the photosynthetic rate increases until a point is reached where the rate begins to level off. At low light intensity, photosynthesis occurs slowly because only a small quantity of ATP and NADPH is created by the light dependent reactions.
Why does light intensity affect the rate of photosynthesis?
As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis.
Does oxygen affect photosynthesis?
Oxygen inhibits the photosynthesis of C3 plants at atmospheric CO2 concentration (Varburg effect). The main cause of this phenomenon is the competitive inhibition of RuBP carboxylation and stimulation of RuBP oxygenation, the latter resulting in formation of glycolate and photorespiratory CO2.
Why does light intensity affect the rate of photosynthesis A level biology?
The rate of photosynthesis increases as light intensity increases: The greater the light intensity, the more energy supplied to the plant and therefore the faster the light-dependent stage of photosynthesis can occur.
What 4 factors can limit the rate 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.
Does temperature affect the rate of photosynthesis?
The rate of photosynthesis is influenced by temperature. Higher the temperature, greater the rate of photosynthesis. This is because photosynthesis is a chemical reaction and most of the chemical reactions are accelerated with temperature.
Does water affect photosynthesis?
Water affects the rate of photosynthesis indirectly. When the water supply is limited then stomatal closure affects the rate of photosynthesis. Water stress causes the stomata to close and thereby reduces carbon dioxide availability.
