Question

why do you need to use a water plant in the process of investigating and collecting the gas produced during photosynthesis?

Answer 1

Plant material will generally float in water. This is because leaves have air in the spaces between cells, which helps them collect CO 2 gas from their environment to use in photosynthesis. When you apply a gentle vacuum to the leaf disks in solution, this air is forced out and replaced with solution, causing the leaves to sink.
