9/5 & 9/6

1

  • Introduction to Mr. Rott & Students
  • Textbook, Computer checkout
  • Google Classroom sign up
  • Activity: Remembering Biology Activity Rotating Posters
  • What makes something Alive Activity 

  • According to the cell theory, living organisms are composed of cells
  • Organisms consisting of one cell carry out all functions of life in that cell
  • Cell Introduction 1.1 Notes

9/7 & 9/10

2

1.5: Origin of Cells

  • Quiz: 1.1 Cell Introduction
  • 7 Conditions of Living Things
  • Discuss: Are Viruses Alive?
  • Pasteur's Experiment
  • Discussion: What controls life?
  • History of Genetic Modification

  • Cells can only be formed by division of preexisting cells
  • The first cells must have arisen from non-living material
  • Application: Evidence from Pasteur’s experiments that spontaneous generation of cells and organisms does not now occur on Earth.
  • Application: Questioning the cell theory using atypical examples, including striated muscle, giant algae and aseptate fungal hyphae.
  • Application: Investigation of functions of life in Paramecium and one named photosynthetic unicellular organism.
  • 1.2 Notes - Ultrastructure of Cells
  • Reading: 98-111

9/11 & 9/12

3

`1.2

  • Quiz 1.2 Prokaryotes
  • Pasteur Experiment Observations
  • Microscope basics and focusing
  • Prokaryote & Eukaryote Lab
  • Prokaryotes have a simple cell structure without compartmentalization
  • Eukaryotes have a compartmentalized cell structure
  • Electron microscopes have a much higher resolution than light microscopes
  • Application: Prokaryotes divide by binary fission.
  • Skill: Drawing of the ultrastructure of prokaryotic cells based on electron micrographs.
  • Skill: Drawing of the ultrastructure of eukaryotic cells based on electron micrograph.
  • Skill: Use of a light microscope to investigate the structure of cells and tissues, with drawing of cells. Calculation of the magnification of drawings and the actual size of structures and ultrastructures shown in drawings or micrographs. (Practical 1)
  • Stem Cells Read pg 415-417

9/13 & 9/14

4

1.1

  • Quiz: 1.2 Eukaryote
  • Complete Prokaryote & Eukaryote Lab
  • Magnification Calculations &  Practice Problems
  • Function of multicellular organisms
  • Emergent Properties
  • Cell Differentiation
  • TED Ed Stem Cells
  • Stem Cells Introduction & Project

  • The capacity of stem cells to divide and differentiate along different pathways is necessary in embryonic development and also makes stem cells suitable for therapeutic uses
  • Application: Use of stem cells to treat Stargardt’s disease and one other named condition.
  • Application: Ethics of the therapeutic use of stem cells from specially created embryos, from the umbilical cord blood of a newborn baby and from an adult’s own tissues.
  • Multicellular organisms have properties that emerge from the interaction of their cellular components
  • Specialized tissues can develop by cell differentiation in multicellular organisms
  • Differentiation involves the expression of some genes and not others in a cell’s genome
  • 1.5 origin of cells notes
  • Pro & Euk Lab
