Topic 2: Cells as the basis of life
The cell is the basic unit of life. All cells possess some common features: all prokaryotic and eukaryotic cells need to exchange materials with their immediate external environment in order to maintain the chemical processes vital for cell functioning. In this topic, students examine the cell theory, the structure and function of the cell membrane, the exchange of materials, and processes required for cell survival. Students investigate the importance of enzymes in cell metabolism and ways in which energy is transformed and transferred in the biochemical processes of photosynthesis and respiration.
Students investigate events that occur during binary fission and mitotic cell division, and how they determine the degree of similarity between parent cells and daughter cells. They also consider the importance of culturing cells, and chemicals that interfere with cell metabolism.
Students explain how the evolution of cells from simpler to more complex structures and functions may have occurred.
In this topic, students expand their scientific literacy skills by using appropriate biological terminology. They extend their numeracy skills through investigating the importance of the microscopic nature of cells.
