In order to store energy, the plants need to photosynthesise at a greater rate than they perform respiration. In low light intensities, less photosynthesis can occur, as there is less light energy available for the light-dependent stage. Therefore, if less respiration is occurring, this allows for the lower rate of photosynthesis, thus allowing the plant to still store energy.
What else can I help you with?
Why does higher light intensities cause the rate of photosynthesis to increase?
Higher light intensities increase the rate of photosynthesis because they provide more energy for the chlorophyll in plants to capture light. This energy is essential for driving the reactions that convert carbon dioxide and water into glucose and oxygen. As light intensity rises, the rate of light-dependent reactions increases, leading to more ATP and NADPH production, which are crucial for the subsequent light-independent reactions. However, this increase continues only up to a certain point, after which other factors may become limiting.
A student was performing an experiment about the rate of photosynthesis in a certain type of algae when it is exposed to different intensities of light What is the independent variable?
The independent variable in the experiment is the intensity of light exposure. This is the factor that the student is manipulating to observe how it affects the rate of photosynthesis in the algae. By changing the light intensity, the student can measure the resulting changes in the photosynthetic rate.
What effects the rate of respiration in plants?
Factors that affect the rate of respiration in plants include temperature, availability of oxygen, and the presence of sugars or other organic compounds that can be broken down for energy. Light intensity and the plant's metabolic activity can also influence respiration rates.

How does light intensity affect the rate of respiration?
Higher light intensity usually increases the rate of photosynthesis, which in turn can lead to higher levels of oxygen being produced. This can stimulate cellular respiration in some organisms as they use oxygen to generate energy. However, excessive light intensity can also damage cells and reduce respiratory activity.
At what light intensity do you expect there to be no net productivity?
No net productivity is expected at the compensation point, where the rate of photosynthesis equals the rate of respiration, typically occurring at low light intensities around 1-10% of full sunlight.
As light intensity increases the rate of photsynthesis?
As light intensity increases at first the rate of photosynthesis also increases. However at higher light intensities the rate of photosynthesis levels off and becmes constant. This is because light is not the only factor needed for photosynthesis. So at high light intensities some other factor is running out eg CO2, temperature, so the extra light cannot be used. At very high intensities photosynthesis can decrease as the chlorophyll is bleached.
Why does higher light intensities cause the rate of photosynthesis to increase?
Higher light intensities increase the rate of photosynthesis because they provide more energy for the chlorophyll in plants to capture light. This energy is essential for driving the reactions that convert carbon dioxide and water into glucose and oxygen. As light intensity rises, the rate of light-dependent reactions increases, leading to more ATP and NADPH production, which are crucial for the subsequent light-independent reactions. However, this increase continues only up to a certain point, after which other factors may become limiting.
When light intensity is below 200 photons do sun plants or shade plants have a higher rate of photosynthesis?
No, shade plants have a higher rate of photosynthesis at lower light intensities. They are more adapted to use the end range of light (red, 730 nm) that is present in shady conditions than sun tolerant plants are.

What are the 2 connections between respiration rate and pulse rate?
The respiration rate is your breathing rate and your pulse rate is your heart beat.
What is respiration rate?
The respiration rate is the number of breaths taken in 1 minute.

The rate of respiration is determined by what levels in the blood?
The rate of respiration is determined by the levels of oxygen and carbon dioxide in the blood. The main controller of the rate of respiration is the brain.
What is the average ratio of the pulse rate to the respiration rate?
The average ratio of pulse rate to respiration rate is typically around 4:1.
