Cell theory

These are the syllabus statements for this section of the syllabus. Topic-2-syllabus-outline

Use this presentation, your textbooks, or any other resources you find helpful to tackle these problems.  We will divide and conquer – a bit like cells specializing in one particular function, each of you will be responsible for one section, and then share your expertise.  This can be notes that you leave as a comment to this post, or a handout for your classmates, or both.

  • Outline the cell theory.
  • Discuss the evidence for the cell theory.
  • State that unicellular organisms carry out all the functions of life.
  • State that multicellular organisms show emergent properties.
  • Explain that cells in multicellular organisms differentiate to carry out specialized functions by expressing some of their genes but not others.
  • State that stem cells retain the capacity to divide and have the ability to differentiate along different pathways.
  • Outline one therapeutic use of stem cells.

Another great presentation on this unit.

We will also consider size (does it matter?) in relation to cells and organisms.  Here is a nice animation to get you thinking.
