IB Biology Review with Complete Solutions cell theory -All living things are composed of cells -cells come from preexisting cells -Cells are smallest unit of life Challenges to cell theory: muscle fibres -They are fused cells, so they're long and have multiple nucleus -challenges cells are autonomous units Challenges to cell theory: Giant algae -certain species may grow large -challenges idea cells are microscopic and larger organisms are composed of many Challenges ...

IB Biology Topic 1: Cell Biology Questions and Answers Already Passed What does cell theory state? That cells are the smallest possible unit of life and that living organisms are made up of cells. What are unicellular organisms? Give two examples Unicellular organisms are organisms with only one cell, such as Paramecium and Chlamydomonas. In unicellular organisms the one cell carries out all of the functions of life. Why are large organisms multicellular? Because of surface area to ...
