Observing Plant Cells
CAROLINA LABSHEETS Quick Links Close Quick Links Open Quick Links Overview Materials Procedures & Prep Kit Overview Materials Procedures & Prep Kit Overview In this lab students observe Elodea leaves under magnification. They will see cell walls and chloroplasts. From the movement of chloroplasts they will infer that cyclosis, or protoplasmic streaming, is occurring. They also will […]
Introduction to Photosynthesis Using Coleus Plants
Carolina LabSheets™ Overview The simple exercises that students perform in this lab demonstrate that plants produce glucose through photosynthesis, that plants convert at least some of the glucose to starch, and that sunlight is a critical factor in photosynthesis. Students expose Coleus leaves to varying amounts of light. These sample leaves are then subjected to an iodine […]
