Mrs. Tracey's email hours 6 am- 8 pm weekdays 

If you are absent from class, many make-ups occur at 7:20 am. This is due to the time it might take to complete the lab. A shorter lab can usually be made up at lunch recess or X block.

Review Guide #2

1- Osmosis moves in our bodies through our cells from high to low concentration areas. Osmosis allows only water to move into and out of the cell through the cell membrane.

2. High= Celery

Low= Salt

The Celery will release water to try and make the concentration level equal of pure water in the salt water. The celery will decrease in size.

3. Diffusion would allow this smell to travel through the house. The high concentration areas is the oven and the low concentration area is the house.

4. The process of osmosis in our bodies is to make water levels equal throughout our bodies. The cell membrane diffuses water into and out of our cells to keep us hydrated.

5. Diffusion moves in our bodies through our cells from high to low concentration areas. Diffusion moves nutrients, blood, and oxygen through the cell membrane.

Review Guide- Check-Up

1. Name the three types of slides that you can use with a microscope. 
WET Mount, DRY mount, Prepared Mount 

2. How is a microscope helpful in the career fields of scientists/researchers?
They can examine small specimens and cells to better understand our living world. 

3. Compare and contrast a plant and animal cell. At least 2 ideas for each area. 

Animal - No cell wall, No chloroplast, do not product own food                
Compare- both found in living things, contain nucleus, cell membrane (to name a few organelles)             
Plant- Contains all major organelles, ability to produce own food, two layers of protection before entering cell 

4. In the data table below, indicate yes or no if the organelle is found in a plant or animal cell. 

Organelle	Plant cell	Animal Cell
Nucleus	Yes	Yes
Chloroplast	Yes	No
Cytoplasm	Yes	Yes
Chromosomes	Yes	Yes
Nuclear Membrane	Yes	Yes
Nucleus	Yes	Yes
Vacuole	Yes	Yes
Mitochondria	Yes	Yes
Cell Wall	Yes	No
Cell Membrane	Yes	Yes
Nuclear Membrane	Yes	Yes

5. Describe the function of each of the organelles in the data table. Use notecards to help you!!! Look at your Its Alive Cell Concept term sheet to help you




6.  What are the three statements of the Cell Theory?
1. All living things contain cells
2. The cell is the basic unit of all living things
3. Only living cells can produce new living cells 

7. Why don’t animal cells have a cell wall?
We have skin that contains lots of layers before we get into the muscle/skeletal system of our bodies. Plants do not have this protection, therefore the cell wall and cell membrane are two layers of protection. 

8. Compare and contrast osmosis and diffusion. At least two ideas for each area. 

Osmosis- water only- can hydrate or dehydrate cells 
Compare-process involved in cells, high- low concentration areas, once areas are equal process stop 
Diffusion- nutrients only - can provide nutrition or malnutrition to a body and its cells 

9. A gummy bear is place in normal tap water for 24 hours. After 24 hour, the gummy bear expanded in size. Explain using high and low concentration areas why this happened. 
High- normal tap water
Low- gummy bear
The water went into the gummy bear from an area of high to low concentration to make the levels equal. 
Is this an example of osmosis or diffusion-osmosis 

10. How is osmosis and diffusion helpful and harmful to our bodies?
Helpful because it makes concentration levels equal. 
Harmful because if we are not well hydrated or eat properly- we could get in a situation of severe dehydration or malnutrition as our cells release water and nutrients to help keep our bodies functioning.
