Row 1, Col 1

What is the difference between a prokaryoteand a eukaryote?

1,2

What is the function of a vacuole?What is the function of a lysosome?

Which of these cell parts is present inan animal cell only?

1,3

What is diffusion? Does it require energy?

Give me an example in your everyday life.

1,4

The cell membrane is selectively (semi) permeable. What does this mean?

What molecules can easily pass through the cell and what molecules cannot?

2,1

What is the difference between a tissueand an organ?

2,2

What is the difference between the Endoplasmic Reticulum and the Golgi Bodies?

2,3

What is osmosis? Does this process requireenergy?

2,4

Iodine is an indicator for starch. It turnsfrom amber to what color in the presence

of starch?

3,1

Place the following levels of organization inorder from simplest to most complex:

OrganismCell

TissueOrgan

Organ System

3,2

What are the functions of the nucleus,Nucleolus and Ribosome?

Inside what cell part are chromosomes?Why are chromosomes considered the

blueprints of the cell?

3,3

What is dynamic equilibrium?

Do molecules ever stop moving duringdynamic equilibrium?

3,4

Using your knowledge of diffusion, explain why our model cell (plastic bag filled with starch) turned

from white to blue black when placed in an Iodine environment?

4,1

Match the scientists to their discoveries

Hooke a. Animals made up of cellsScheilden b. Plants made up of cellsVirchow c. Came up with the term cellsSchwann d. Cells come from other cellsVan Leeuwenhoek e. Observed unicellular organisms

4,2

What are four differences betweenPlant and Animal Cells?

4,3

Using your knowledge of osmosis, explain whyyou feel thirsty after eating a salty meal?

Explain why a gummy bear will expand when placedin distilled water (100% water)

4,4

Starch did not diffuse out of the model cell, eventhough there was a greater concentration inside

the cell than outside the cell. What does this sayabout the size of the starch? Iodine diffused into

the cell, what does that say about the size of iodine?

5,1

What are the three parts of the cell theory?

5,2

Plant cells have chloroplasts and animal cells do not.

Explain the function of the choroplast!

Plant & Animal cells both have mitochondria!Why is the mitochondria so important for both

plants and animal cells?

5,3

What are two differences between PassiveTransport and Active Transport?

5,4

Using your knowledge of osmosis, explain the following:

1.Why did the egg expand when placed in vinegar?2.Why did the egg shrink when placed in corn syrup?
