Cell Membrane and Transport
Test 10/4
Cell membrane and transport notes
Essential Standard:
Bio 1.2 Analyze the Cell as a Living System
Bio 4.2 Analyze the relationships between biochemical processes and energy use in the cell
Clarifying Objectives:
Bio 1.2.1 Explain how homeostasis is maintained in a cell and within an organism in various environments (including temperature and pH)
Bio 4.2.2 Explain ways that organisms use released energy for maintaining homeostasis (active transport).
Unpacking – What does this standard mean a child will know, understand, and be able to do?
Bio.1.2.1
• Explain how cells use buffers to regulate cell pH and how cells can respond to maintain temperature, glucose levels, and water balance in organisms.
• Compare the mechanisms of active vs. passive transport (diffusion and osmosis).
• Conclude how the plasma membrane structure functions.
• Explain changes in osmotic pressure that occurs when cells are placed in solutions of differing concentrations.
Bio 4.2.2
Conclude that energy production by organisms is vital for maintaining homeostasis and that maintenance of homeostasis is necessary for life. Examples: Active transport of needed molecules or to rid the cell of toxins; movement to avoid danger or to find food, water, and or mates; synthesizing needed molecules.
Key Vocabulary:
3rd Tier Words: homeostasis, passive transport, diffusion, facilitated diffusion, osmosis, cell (plasma) membrane, selectively permeable, phospholipid bilayer, pores, transport proteins, concentration gradient, osmotic/turgor pressure, equilibrium, active transport, cytolysis, plasmolysis, sodium-potassium pump, dynamic equilibrium, fluid mosaic model, polarity, hydrophilic, hydrophobic, tonicity, solute, solvent, ions, protein channel, transport protein, exocytosis, endocytosis, pinocytosis, phagocytosis, distilled water, hypotonic, isotonic, hypertonic, concentration
2nd Tier Words: pigment, recycled, affect, effect, expand, control, collect, inflate, produce, interact, span, interior, exterior, barrier, submerge, distributed, maintain, net movement, shrivel, turgid, flaccid, wilt, steep, composed
Common Misconceptions:
1.2.1
How do cells maintain conditions suitable for life in different environments?
How do materials get in/out of cells?
4.2.2
Why do organisms need energy?

Common Misconceptions:
- Particles move from high to low concentration because they tend to move until the two areas are isotonic and then the
particles stop moving. - There are too many particles crowded into one area, therefore they move to an area with more room.
- Exocytosis is the same as active transport.
1.2.1
How do cells maintain conditions suitable for life in different environments?
How do materials get in/out of cells?
- I will describe examples of maintaining homeostasis in living cells
- I will describe how the structure of the cell membrane allows for the transport of materials
- I will explain the mechanisms of passive transport
- I will predict what will happen to cells that are placed in different environments when given numerical or descriptive data
- I will explain the mechanism of active transport and compare/contrast to passive transport
4.2.2
Why do organisms need energy?
- I will evaluate an organism’s need for energy and relate to the STERNGRR life processes (synthesis of molecules, transport of materials, growth, reproduction)
- I will explain that in order for an organism to maintain homeostasis, energy is required for the STERNGRR life processes (synthesis, excretion, regulation).
- I will provide examples of maintaining homeostasis and relate to STERNGRR and the need for energy.
