Cell Boundaries
Every cell is surrounded by a liquid environment and has a liquid inside
Two types of boundaries separate:
– Cell membrane (inner)• Thin, flexible layer that surrounds all cells
– Cell wall (outer)• Strong supporting layer outside the cell membrane• Only in some organisms (plants, algae, fungi, prokaryotes)• Porous

FUNCTION of Cell Membrane
• Regulates what goes in and
what comes out of a cell– Like a fence or a window screen– Regulation depends on size, concentrations,
and the type of molecule trying to get through
• Protects cell
• Supports cell, but also flexible

Pre-Class QuestionsWrite in Notebook…I will call on you!
• Why is it necessary to regulate what goes in and out of a cell?
• What are some examples of substances that enter a cell? Leave a cell?
• What does the term concentration mean?– Provide an example to explain concentration

FUNCTION of Cell Membrane
• Regulates what goes in and
what comes out of a cell– Regulation depends on size, – concentrations, – type of molecule trying to get through
• Protects cell
• Supports cell, but also flexible

Cell Boundaries
Everything has a Cell membrane (inner)
Some stuff has a Cell wall (outer)
• Strong & rigid• Only in some organisms (plants, algae, fungi, prokaryotes)

Figure 7-12 The Structure of the Cell Membrane
Fluid Mosaic Model• Lipid bilayer – double layer of molecules
– Lipids are a certain class of C-H molecules – Do not like water ( think of oil + water) – the “tails”– The “heads” are polar molecules
• Has proteins throughout • Can have carbohydrate “ID tags”• Moveable/fluid• Selectively Permeable

What goes in and out? (Transport)Cell membrane is selectively permeable,
it lets some things in, but not other things
Selection depends on…
size (smaller get through easily)
concentrations,
& type of molecule trying to get through
(lipid and nonpolar)
https://www.youtube.com/watch?v=IaZ8MtF3C6M• Substances keep moving till there are ~ equal
amounts of them on both sides of the membrane EQUILIBRIUM

Prokaryote vs. EukaryoteAll cells have a membrane, cytoplasm, DNA & ribosomes
• Prokaryotic Cells
– DNA not bound by a membrane… no “true nucleus”
– Usually smaller, simple – No membrane bound
parts (organelles)– Ex: bacteria
• Eukaryotic Cells
– Membrane bound nucleus
– Larger, complex, internal organization
– Have internal membrane bound structures
– Ex: you, plants, algae

Speed Dating Organelles
• Today you will research a specific organelle and use the brainstorm planning sheet (two-sided) to construct a profile of your organelle
• Towards the end of the period, I will give you the ‘good copy’ to be used tomorrow.
• Tomorrow, we will have a ‘speed dating’ session and your job will be to meet everyone & decide which organelle(s) you’re most closely matched with

Organelle Speed Dating!
Goal: Find the organelle(s) that work most closely with your
organelle

Find a seat!
If you are seated in the inner circle,you’ll stay there for most of the activity
If you’re seated on the outside, each time I call “time”, you will rotate one seat to your right.
For 1:30 you will converse with your new Organelle friend Take turns sharing & explaining your job!

• Living things respond to environment
ex. Find shelter from rain
ex. Hibernating to survive the winter
ex. Produce toxins to ward off predators• Living things maintain a stable internal environment
– Homeostasis: keeping internal condition stable relative to the external environment
Characteristics of Living Things - Homeostasis
