Learning Target:To understand how plant and animal cell differ in cell organelles and the functions of those organelles.

Learning Outcome:I will complete the Plant and Animal Cell Lab.

Create detailed drawing of all of what you see, not just one cell. Identify the following:

Animal Cell – Nucleus, Cell Membrane, Cytoplasm and Endoplasmic Reticulum.

Plant Cell – Cell Membrane, Cell Wall, Chloroplast, Water Vacuole, and Nucleus (?).

*See if the chloroplast are moving.

Learning Target:Know the structure and function of the cell membrane including lipid bilayer, protein channels and pumps.

Learning Outcome:I will complete cell membrane model.

Cell Membrane Section 7-3

Function: To regulate what enters and leaves the cell and aids in protection and support.

1. Lipid bilayer – 2 layers

2. Proteins PumpsChannels

3. Carbohydrates – attached to proteins

Act as name tags or ID cards so cells can recognize each other

Learning Target:Be able to describe the process of osmosis as it occurs in hypertonic, hypotonic and isotonic solutions.

Learning Outcome:I will complete the “Observing Osmosis Lab” write-up.

Draw a diagram that answers the following questions:

(1)What substances does the cell allow to go in and out? (labeled arrows)

(2)What substances does the cell keep in or out (circled labels).

Diffusion:• The

movement of molecules from high to low concentration.

Osmosis:• The diffusion of WATER through a

selectively permeable membrane

Isotonic Solution:• Equilibrium• Water will move

both in and out• Cell will not

change shape

Hypertonic Solution: (Above strength)• Solution has a higher solute concentration than the

cell.• Water will move out of cell• Cell will shrink

Hypotonic Solution: (Below strength)• Solution has a lower solute concentration than the cell.• Water will move into the cell• Cell will swell

Facilitated Diffusion:• Use of a protein

channel to cross through a cell membrane

Active Transport:•Sometimes materials need to move in opposite concentration gradients (low to high)

•Requires energyEndocytosis (into cell)Phagocytosis (takes food in)Pinocytosis (takes water in)

Exocytosis (out of cell)

Active Transport: Notice the energy (ATP) required to move molecules AGAINST the gradient!! (low to high)
