Assertion (A): Leaves of plants are green.
Reason (R): Plants contain chromoplasts, the green pigment.
The correct answer for this question is option 'C', which states that Assertion (A) is true but Reason (R) is false.
Explanation:
- The Assertion (A) states that leaves of plants are green. This is a well-known fact and is true. The green color of leaves is due to the presence of a pigment called chlorophyll, which is responsible for photosynthesis.
- The Reason (R) states that plants contain chromoplasts, the green pigment. This statement is incorrect. Chromoplasts are a type of plastids found in plants, responsible for the synthesis and accumulation of pigments other than chlorophyll. They are responsible for the red, orange, and yellow colors seen in fruits, flowers, and some leaves, but not green. The green color in plants is specifically due to chlorophyll, which is found in chloroplasts.
- Chloroplasts are specialized organelles found in plant cells that contain chlorophyll and are responsible for photosynthesis. These organelles capture sunlight and convert it into energy, which is used by the plant for growth and development.
- Chlorophyll is a green pigment that absorbs light in the blue and red regions of the electromagnetic spectrum and reflects green light, giving leaves their characteristic green color.
- The presence of chlorophyll in chloroplasts enables plants to capture light energy and convert it into chemical energy through photosynthesis. This process is crucial for the survival of plants and the production of oxygen and carbohydrates.
- In conclusion, Assertion (A) is true because leaves of plants are indeed green. However, Reason (R) is false because plants do not contain chromoplasts responsible for the green color. Instead, chlorophyll in chloroplasts is responsible for the green color of leaves.
Reason (R): Plants contain chromoplasts, the green pigment.
