In this unit, students will be covering the basic of cell theory. From there, students will learn to differentiate between prokaryotic and eukaryotic cells, draw and label the cells and also identify the functions of the organelles found within the cells. Experiments on observing plant and animal cells will be done including teaching students the proper technique of mounting and staining of cells and measuring the size of cells. Students will also learn about the chemical make-up of the plasma membrane and the functions of the membrane proteins found in the phospholipid bilayer. Methods of transport like diffusion, facilitated diffusion, osmosis, active transport, endocytosis and exocytosis will be introduced. Experiments will be done to identify the effect of water molecules or solutes on the size of the cells. The last sub-unit will be on cell division where students will understand the process leading to cells multiplying in number rapidly which includes the mitosis process.
The evolution of multicellular organisms allowed cell specialization and cell replacement.
