Answer
Chlorophyll plays a crucial role in photosynthesis by trapping sunlight energy, which energizes electrons and facilitates the process of converting light energy into chemical energy. This energy is essential for the synthesis of carbohydrates from carbon dioxide and water.

Answer
Water travels from the soil to the leaf primarily through xylem vessels. This movement is driven by root pressure and the tension created by water evaporation from the leaf surfaces (transpiration).
Step 8
