Are Fruits And Vegetables Really Made of Cells?
Young scholars design and carry out an exercise to determine if a given fruit or vegetable is composed of cells. They dissect out sections of the fruit or vegetable, prepare stained slides, and make observations under a compound microscope.
Curated OER
Mitosis & Cell Processes
Students research the process of mitosis and how it progresses to the finished result of cell division. They reflect upon how this causes organisms to grow larger and helps tissues to be renewed.
