ESSENTIAL IDEA:
The evolution of multicellular organisms allowed cell specialization and cell replacement.
ESSENTIAL QUESTIONS:
Where did the first cells come from?
Why are cells so small?
Are all living things made of cells?
Do all cells share the same structure?
What are the main processes of life that happen in a cell?
UNDERSTANDINGS / APPLICATIONS / NATURE OF SCIENCE
1.5.U1: Cells can only be formed by division of preexisting cells.
1.5.NOS: Testing the general principles that underlie the natural world- the principles that cells only come from preexisting cells needs to be verified.
1.5.A1: Evidence from Pasteur’s experiments that spontaneous generation of cells and organisms does not now occur on Earth.
1.5.U2 The first cells must have arisen from non-living material.
1.1.U1: According to the cell theory, living organisms are composed of cells.
1.1.A1: Questioning the cell theory using atypical examples, including striated muscle, giant algae and aseptate fungal hyphae.
1.1.NOS1: Looking for trends and discrepancies - although most organisms conform to cell theory, there are exceptions
1.1.U2: Organisms consisting of only one cell carry out all functions of life in that cell.
1.1.A2: Investigation of functions of life in Paramecium and one named photosynthetic unicellular organism.
1.1.U3: Surface area to volume ratio is important in the limitation of cell size.
