2. Learner Outcomes:
To describe the characteristics and identify the monomers of lipids, proteins, carbohydrates, and nucleic acids and to define their role in biochemical processes.
To analyze and explain the chemical reactions the provide energy for the body.
To investigate and describe the integration of the chemical and physical properties that contribute to homeostasis in cells.
To compare the structures and functions of organelles within cells of the body.
To describe the processes involved in the cell cycle.

3. Eukaryotic Cells
With the exception of symbiotic and parasitic relationships with bacteria, all of the cells of our body are eukaryotic.
What does this mean?

4. Eukaryotic Cells Plasma membrane Nucleus and Nucleolus
Cytoplasm containing organelles
Each of our bodies exhibits specialization. The presence or absence of some organelles and their arrangements vary dependant on the needs of the cell.

6. Cellular Homeostasis – the plasma membrane
Semi-permeable or Selectively permeable
2 methods used in crossing the membrane – active and passive
Active transport requires the use of ATP. Which organelle provides this high-powered molecule for the cell?
Passive transport uses the principles of diffusion to cross the membrane and does not require the use of ATP.
