Plant leaves obtain different colours due to the presence of different types of pigment like carotinoids (yellow, orange), anthocyanin (purple) etc. But chlorophyll is also present on these leaves but remains hidden or musked among other pigments. These chlorophylls perform photosynthesis just like other green plants. So coloured plant leaves also carry out photosynthesis like green plants.

Plants with Deep Red, Violet, or Brown Leaves and Photosynthesis

Plants with deep red, violet, or brown leaves are capable of carrying out the process of photosynthesis, just like plants with green leaves. However, the pigments responsible for their leaf coloration differ, which affects the way they absorb and utilize light energy for photosynthesis.

1. Overview of Photosynthesis:
Photosynthesis is a vital process in plants that converts light energy from the sun into chemical energy. This energy is then used to synthesize glucose and other organic compounds, providing fuel for the growth and development of the plant.

2. Chlorophyll and Absorption of Light:
Chlorophyll is the primary pigment responsible for the green color of most plants' leaves. It plays a crucial role in capturing light energy for photosynthesis. Chlorophyll molecules absorb light in the blue and red regions of the electromagnetic spectrum, while reflecting or transmitting green light, which gives plants their characteristic green appearance.

3. Other Pigments and Leaf Coloration:
Plants with deep red, violet, or brown leaves contain additional pigments, such as anthocyanins or carotenoids, that complement or mask the green color of chlorophyll.

- Anthocyanins: These pigments produce red, purple, or blue colors in plants. They are often synthesized in response to environmental stressors like high light intensity or cold temperatures. Anthocyanins have been found to protect the plant by absorbing excess light energy and acting as antioxidants.
- Carotenoids: These pigments are responsible for the yellow, orange, and red hues seen in many plants. They serve as accessory pigments, complementing chlorophyll by absorbing light in different regions of the spectrum. Carotenoids also act as photoprotective agents, preventing damage from excess light energy.

4. Photosynthesis in Plants with Deep Red, Violet, or Brown Leaves:
Despite having different pigments, plants with deep red, violet, or brown leaves still undergo photosynthesis. While chlorophyll is the primary pigment for capturing light energy, the additional pigments in these plants allow them to utilize a broader range of light wavelengths.

- Light Absorption: The pigments in red, violet, or brown leaves absorb light energy in different regions of the spectrum, including blue, red, and even green light. This absorbed energy is then transferred to chlorophyll, which initiates the photosynthetic process.
- Photosynthetic Pathways: Plants with different pigments may have slightly altered photosynthetic pathways due to variations in light absorption. However, the fundamental process of converting light energy into chemical energy remains the same.

In conclusion, plants with deep red, violet, or brown leaves are capable of photosynthesis. While chlorophyll is the primary pigment for capturing light energy, the additional pigments present in these plants allow them to absorb a broader range of wavelengths. This adaptation enables them to thrive and carry out photosynthesis even with different leaf colors.

Yes,plants having deep red,violet or brown leaves photosynthesize like other plants....they have still some chlorophyll but because of in small amont it is not expressed
