2.5 Cell division
Approach : Cell is the basic unit of life & cells arise from preexisting cells. Our life is only possible due to individual function of a cell as well as collective, controlled & collaborative functions of cells. Cells have a definite structure & function. Class discussions make them to understand the basic concepts of cell. As cells are microscopic so are difficult to measure and needs microscopy to study. Lab work on magnification & measurement enable the students to know the actual size of cells. Cell maintains homeostatic conditions through controlling transport of materials through its membranes. Animations listed here will help them to understand this concept. The advent of therapeutic use of stem cells has led to a debate on social, religious & ethical issues. They will be asked to have a debate on this issue.
Statistics are the mathematical methods of interrogating data.
Students will be taught not to get hung-up on the mathematics, instead concentrate on the purpose of each test and the type of data they must be used on using power point presentations .
Teaching methodologies to be employed in this unit include:
1. Discussions
2. Set assignments.
3. Use of text books
4. Use of whiteboard
5. Use of power point presentations.
6. Use of websites
7. Regular review and feedback on students’ performance
8. Animations on
Absorption animation - diffusion, facilitated diffusion, active transport are shown in the duodenum
Osmosis animation
Facilitated Diffusion animation
Active Transport animation

Subject: …………………............……..
Students will be made familiar with these topics through explanations & class discussions. They are asked to have a debate on stem cell technology.
Students are asked :Go to http://click4biology.info/c4b/2/cell2.htm
& browse through for topics 1 & 2 and Go to http://learn.genetics.utah.edu/content/begin/cells/scale/ to understand cell size & scale.
Student’s IA skills will be developed by making them to do practical on: Identifying and measuring cells and Investigate the effect of different solute concentration in potato tuber cells
Assessment would be based on variety of things like worksheets, written assignments, home work, lab work etc will help them to attempt for formative
& summative assessment.
Previous knowledge will be judged through class interaction.
Considerations:
Guiding Question: To what extent can we be sure that all life is cellular? OR How ethical is, the creation of new life from cells in vitro?
Learner Profile :
Inquirer: : Student will be made to inquire about the factors affecting the movement of water through cell membrane. They will also inquire that how does the size of a cell affects its functioning.
Knowlegeable: They explore the ethical implications of stem cell technology
ICT : Virtual Lab & Use of data loggers for comparing cell surface area & volume ratio and physiology of cell.
Information literacy : They are asked to research on ethical, moral & social implications of stem cell technology.
International Mindedness : Many nations have banned or limited the research on stem cell technology due to local, cultural
&religious traditions. Where do you stand in the debate about the nature of this research?

TOK: This is an opportunity to discuss balancing the huge opportunities of therapeutic cloning against the considerable risks —for example, stem cells developing into tumors.
Another issue is how the scientific community conveys information about its work to the wider community in such a way that informed decisions about research can be made.
Differentiation: Core syllabus would be taught to HL and SL together. AHL topics would be taught to HL students only in extra periods while SL students would solve the wok-sheets or will have hands on practical skills.
