Answer
One of the charged carriers produced during the light-dependent stage of photosynthesis is ATP (adenosine triphosphate), which plays a crucial role in energy transfer.

Answer
The additional photosynthetic pigments, such as carotene and chlorophyll b, serve the purpose of absorbing different wavelengths of light. This allows plants to utilize a broader spectrum of light energy for photosynthesis, increasing their overall efficiency.

Answer
Species X appears to retain its leaves throughout winter, as indicated by the maintained presence of pigments in the observed months. This suggests it belongs to the group of trees that have leaves year-round, as opposed to those that shed their leaves.
