Plants are green in colour because

Options

A. they absorb green light only
B. they reflect green light
C. they absorb green light but reflect all other lights
D. none of the above are correct.

Answer

**Step-by-Step Solution:**

1. **Understanding Light and Color**: Light is made up of different colors, which can be represented by the acronym "VIBGYOR" (Violet, Indigo, Blue, Green, Yellow, Orange, Red). When light hits an object, we see the colors that are reflected by that object.

2. **White Light**: White light, such as sunlight, is a combination of all these colors. When it shines on a plant, it interacts with the plant's leaves.

3. **Role of Pigments**: Plants contain pigments, the most important of which is chlorophyll. This pigment plays a crucial role in photosynthesis, the process by which plants convert light energy into chemical energy.

4. **Absorption and Reflection of Light**: When white light falls on the leaves, chlorophyll absorbs certain wavelengths of light (mainly blue and red light) and reflects others.

5. **Why Plants Appear Green**: Chlorophyll specifically reflects green light. This is why we perceive the leaves of plants as green. The green light is not absorbed but rather reflected back to our eyes.

6. **Conclusion**: Therefore, plants are green in color because they contain chlorophyll, which reflects green light while absorbing other colors.
