Which function do the stomata perform in photosynthesis?
Which step in photosynthesis does not need light?(
A scientist performs an experiment by placing petroleum jelly on plant leaves, which blocks the leaves’ stomata. Which result would the scientist observe?
How many carbon atoms combine in the photosynthesis reaction?
these are not answers the are the thing i need help with
1. The stomata perform the function of regulating the exchange of gases, including carbon dioxide and oxygen, during photosynthesis.
2. The dark reaction or the Calvin cycle does not need light.
3. If the scientist places petroleum jelly on plant leaves, which blocks the leaves' stomata, the result would be a decrease in the rate of photosynthesis due to the limited availability of carbon dioxide.
4. Six carbon atoms combine in the photosynthesis reaction to form one glucose molecule.
1. The stomata perform the function of regulating gas exchange in photosynthesis. They control the entry of carbon dioxide (CO2) into the leaves, which is a necessary component for the process of photosynthesis.
2. The step in photosynthesis that does not require light is called the Calvin cycle, also known as the dark reactions or light-independent reactions. This step occurs in the stroma of the chloroplast and involves the conversion of carbon dioxide into glucose.
3. If a scientist places petroleum jelly on plant leaves, blocking the stomata, the result would be a reduced rate of gas exchange. This would lead to a decrease in the uptake of carbon dioxide (CO2) necessary for photosynthesis. As a result, the plant's growth and production of carbohydrates may be negatively affected.
4. In the overall photosynthesis reaction, six molecules of carbon dioxide (6CO2) combine with six molecules of water (6H2O) to produce one molecule of glucose (C6H12O6). Therefore, six carbon atoms combine in the photosynthesis reaction.
To answer these questions, we need to have an understanding of the process of photosynthesis. Photosynthesis is the process by which plants convert carbon dioxide and water into glucose (sugar), using sunlight as the source of energy. It takes place in the chloroplasts of plant cells.
1. Which function do the stomata perform in photosynthesis?
Stomata are small openings on the surface of plant leaves, primarily on the undersides. They play an important role in photosynthesis by facilitating the exchange of gases. During photosynthesis, carbon dioxide enters the plant through the stomata and oxygen is released as a byproduct.
2. Which step in photosynthesis does not need light?
Photosynthesis consists of two main reactions: the light-dependent reactions and the light-independent reactions (also known as the Calvin cycle). The light-dependent reactions require sunlight and take place in the thylakoid membrane of the chloroplasts. In contrast, the light-independent reactions, which occur in the stroma of the chloroplasts, do not require light directly. However, they depend on the products generated in the light-dependent reactions, such as ATP and NADPH.
3. A scientist performs an experiment by placing petroleum jelly on plant leaves, which blocks the leaves’ stomata. Which result would the scientist observe?
By blocking the stomata with petroleum jelly, the exchange of gases (such as carbon dioxide and oxygen) through the stomata is hindered. Consequently, the availability of carbon dioxide for photosynthesis would be reduced, resulting in a decrease in the rate of photosynthesis. This can lead to reduced plant growth and development.
4. How many carbon atoms combine in the photosynthesis reaction?
During photosynthesis, six carbon dioxide (CO2) molecules combine with six water (H2O) molecules to produce one glucose (C6H12O6) molecule. Therefore, six carbon atoms combine in the photosynthesis reaction to form glucose.
