Main & most obvious reason - lack or absence of sunlight. Other external factors include not enough carbon dioxide and ambient temperatures that are too hot or too cold.
There could also be other factors such as a genetic disorder in plants that cause a lack of chlorophyll If the soil type is incorrect, or the water content incorrect, normal processes within the organism will not occur
A plant's stomata are generally open during the day to allow for the exchange of gases like carbon dioxide and oxygen needed for photosynthesis. They are closed at night to prevent water loss through transpiration when photosynthesis is not occurring.
A spectrophotometer could be used to monitor the rate of photosynthesis in a plant by measuring the absorption of light by chlorophyll.
The bubbles produced by pondweed during photosynthesis underwater contain oxygen gas. This is a byproduct of the process and indicates that photosynthesis is occurring. If the experiment permits the bubbles to escape, they can be collected and tested to confirm the presence of oxygen.
You can measure the rate of photosynthesis by monitoring the levels of oxygen and carbon dioxide within the sealed box over time. As the plant undergoes photosynthesis, it will produce oxygen and consume carbon dioxide, leading to changes in the gas concentrations. By measuring these changes, you can determine the rate of photosynthesis occurring.
During photosynthesis, plants use light energy to convert carbon dioxide and water into glucose and oxygen. This process occurs in the chloroplasts of plant cells and is crucial for plant growth and survival. Additionally, photosynthesis helps produce oxygen, which is essential for life on Earth.
Brain cells
You could look for the presence of chlorophyll, which is necessary for photosynthesis to occur. Additionally, you could observe if the leaf is green and healthy-looking, as plants that are actively carrying out photosynthesis tend to have vibrant foliage. Finally, you could check for the production of oxygen bubbles through a simple experiment to confirm the occurrence of photosynthesis.
Photosynthesis.
How can temperature either help fusion to occur or prevent fusion from occurring?
Photosynthesis is the process
A plant's stomata are generally open during the day to allow for the exchange of gases like carbon dioxide and oxygen needed for photosynthesis. They are closed at night to prevent water loss through transpiration when photosynthesis is not occurring.
No. There is no way for us to prevent tornadoes. We cannot control nature.
The Calvin cycle, a series of biochemical reactions that occur during photosynthesis, takes place in the stroma of the chloroplast, which is a compartment within the plant cell where photosynthesis occurs.
Sometimes you can prevent conflicts by walking away from the conflict.
Two common examples are photosynthesis and cellular respiration.
Contraceptives are used to prevent pregnancy from occurring.
You can't stop them from occurring, you just have to learn to deal with them by being better prepared.
