Sample Data
| Front | Formula for Magnification |
| Back | Magnification = Image size / Actual size |
| Front | What are the functions of each subcellular structure?
 |
| Back | Nucleus - Contains genetic material that controls the activities of the cellCytoplasm - Gel-like substance where most chemical reactions occur, and contains enzymes to control these reactionsCell membrane - Holds the cell together and controls what goes in and outMitchondria - Where majority of aerobic respipration occurs for energyRibosomes - Where proteinsynthesis takes place for growthCell wall - Made of cellulose and strengthens the cellVacuole - Contains cell sap (sugar and salts), holds food for later, and waste for removalChloroplast - Where photosynthesis occurs, and contain chlorophyll to absorb light needed for photosynthesis |
| Front | Describe the stages in the Mitosis (Cell Cycle) |
| Back | Interphase - In this stage, the DNA is spread in a long string, the cell grows as the organelles grow, and the synthesis of proteins occurs, chromsomes are duplicated, to form 92 chromosomes, so there's one copy for each cell, and energy stores are increased.Mitosis - The chromosmes line up at the equator of the cell, and cell fibres pull each chromosome to opposite poles of the cellCytokinesis - Two identical daughter cells are formed when the cytoplasm, and cell membranes divide |
