Conclusion. Photosynthetic cells contain chlorophyll and other light-sensitive pigments that capture solar energy. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as glucose.
What do pigment molecules do?
Pigments are colorful compounds.
More important than their reflection of light is the ability of pigments to absorb certain wavelengths. Because they interact with light to absorb only certain wavelengths, pigments are useful to plants and other autotrophs –organisms which make their own food using photosynthesis.
Which of the following molecules are needed for photosynthesis?
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.
Why do plants have different types of pigment?
Multiple pigments absorb different wavelengths of light, allowing the plant to capture the maximum amount of energy from the sun. … Multiple pigments allow the plants to have different colors of leaves, which allows them to capture the maximum amount of energy from the sun.
What process does not require sunlight?
Answer: The part of photosynthesis that does not require sunlight responses is called the carbon fixation phase. Explanation: … The phase called carbon fixation occurs in the chloroplast stroma and does not need sunlight to occur.
Which is the final step in photosynthesis process?
The last stage of the photosynthesis process is known as the Calvin-Benson cycle, in which the plant uses atmospheric carbon dioxide and water from soil to convert ATP and NADPH. The chemical reactions that make up the Calvin-Benson cycle occur in the stroma of the chloroplast.
What molecules are the major source of energy for cells?
Adenosine 5′-triphosphate, or ATP, is the most abundant energy carrier molecule in cells. This molecule is made of a nitrogen base (adenine), a ribose sugar, and three phosphate groups.
Which out of them is raw material for photosynthesis?
The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf.
