Photosynthesis Lab

Plant Science students boil leaves in water first and then in rubbing alcohol to extract the chorophyll.

Leaves are flooded with iodine to examine the starch deposits present from the process of photosynthesis.

Sections of plant leaves were covered with black paper leaving a small opening for light to strike the leaf surface. The chlorophyll extraction procedure is performed and students compare starch deposits in covered and uncovered sections of the leaf.
