5. Why photosynthesis is named so?
6. Give a brief description of the process of synthesis of food in green plants.
7. Mention the significance of chlorophyll in leaves.
8. Sun is the ultimate source of all living organisms. Justify this statement.
Answers
the explanation for the questions are
5. because the food in plants are synthesized in the presence of light(photo).
6. Carbon dioxide+ water in the presence of light and chlorophyll gives rise to carbohydrates+oxygen.
7. chlorophyll is the green pigment which absorbs the light energy from the sun.
8. the reaction of photosynthesis take place only in the presence of solar energy and these plants are autotrophs and other heterotrophs are completely dependent on autotrophs.
Answer:
Explanation:
5. Photosynthesis is named so because it utilises light to synthesise food from carbon dioxide and water. Photo means Light and synthesis means making
6. The leaves have a green pigment called chlorophyll. It helps leaves to capture the energy of the sunlight. This energy is used to synthesize (prepare) food (carbohydrates) from carbon dioxide and water. Since the synthesis of food occurs in the presence of sunlight, it is called photosynthesis.
7. The role of chlorophyll in photosynthesis is vital. Chlorophyll, which resides in the chloroplasts of plants, is the green pigment that is necessary in order for plants to convert carbon dioxide and water, using sunlight, into oxygen and glucose
8. Image result for Sun is the ultimate source of all living organisms. Justify this statement.
"Sun is the ultimate energy source for all living organisms." ✴This is because plants need sunlight to make food through photosynthesis. This food is consumed by the animals and human-beings.
