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.

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.
![Page 10: Learning Target: To understand how plant and animal cell differ in cell organelles and the functions…](https://reader035.fdocuments.in/reader035/viewer/2022081606/5a4d1bdc7f8b9ab0599dccd7/html5/thumbnails/10.jpg)
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
![Page 12: Learning Target: To understand how plant and animal cell differ in cell organelles and the functions…](https://reader035.fdocuments.in/reader035/viewer/2022081606/5a4d1bdc7f8b9ab0599dccd7/html5/thumbnails/12.jpg)
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
![Page 15: Learning Target: To understand how plant and animal cell differ in cell organelles and the functions…](https://reader035.fdocuments.in/reader035/viewer/2022081606/5a4d1bdc7f8b9ab0599dccd7/html5/thumbnails/15.jpg)
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)
![Page 16: Learning Target: To understand how plant and animal cell differ in cell organelles and the functions…](https://reader035.fdocuments.in/reader035/viewer/2022081606/5a4d1bdc7f8b9ab0599dccd7/html5/thumbnails/16.jpg)
Active Transport: Notice the energy (ATP) required to move molecules AGAINST the gradient!! (low to high)
