Given below is a diagrammatic representation of cross-section of a leaf: [figure]
(i) Identify 'P' in the given diagram and write down its role in plants.
(ii) Write down a balanced equation of process of photo-synthesis.
Given below is a diagrammatic representation of cross-section of a leaf: [figure]
(i) Identify 'P' in the given diagram and write down its role in plants.
(ii) Write down a balanced equation of process of photo-synthesis.
Official answer
P is the chloroplast in the given diagram. Chloroplasts are organelles found in plant cells where photosynthesis takes place. They contain the pigment chlorophyll, which absorbs light energy from the sun and uses it to convert carbon dioxide and water into glucose and oxygen through the process of photosynthesis.
Marking scheme
- 1.Identification of chloroplasts
- 2.Explanation of role of chloroplasts in photosynthesis
- 3.Balanced equation for photosynthesis
Hint
Look for the organelles that contain chlorophyll and are responsible for absorbing light energy.
Quick oral answer
Chloroplasts are the organelles found in plant cells where photosynthesis takes place. They contain the pigment chlorophyll, which absorbs light energy from the sun and uses it to convert carbon dioxide and water into glucose and oxygen.
Common mistakes
- 1.Confusing chloroplasts with other organelles
- 2.Incorrectly identifying the reactants or products of photosynthesis
Analysis and explanation
The question requires the student to identify the chloroplasts in the diagram and explain their role in photosynthesis. The student should be able to recognize the chloroplasts as the site of photosynthesis and understand the process of photosynthesis, including the reactants, products, and energy source.
Interesting facts
Chloroplasts are found in plant cells and are responsible for photosynthesis.
Photosynthesis is the process by which plants convert light energy into chemical energy.
