Which part of the plant is responsible for photosynthetic activity besides leaves?

• A. Roots
• B. Flowers
• C. Green stems
• D. Seeds

Answer: (C)

The part of the plant responsible for photosynthetic activity besides leaves is the green stems. Green stems contain chlorophyll, the green pigment that captures light energy for photosynthesis. While leaves are the primary site for photosynthesis, stems that are green can also perform this vital function. This is particularly important for young plants or plants that may not have fully developed leaves yet, as they still need to produce energy through photosynthesis for growth and development.

Other parts of the plant, such as roots, flowers, and seeds, do not significantly contribute to photosynthesis. Roots primarily function to absorb water and nutrients from the soil, flowers are mainly involved in reproduction, and seeds are crucial for propagation but not for photosynthetic activity. Therefore, the presence of chlorophyll in green stems allows them to contribute to the plant's overall ability to harness energy from sunlight effectively.
