Warm-Up: Cell organelle challenge!• Near the top of your paper you should see “Warm-

Up” and the numbers 1-7

• I’ll show a picture of a eukaryotic cell organelle, all you have to do is write down what organelle it is.

• You can use your notes from last week to help you. (Cell organelle booklet, organelle chart that we cut and pasted)

• Perfect scores get bonus points!

1. What are these green organelles in a

plant called?

2. What is organelle #2 in this diagram?

3. What is this organelle that makes energy for the cell?

4. What is this organelle near the nucleus that has lots of folded membranes and is a home for ribosomes?

Nucleus

This is a picture of a lung cell

5. This organelle is usually bigger in plants and when full of water helps the plant

stand tall.

6. What is it that surrounds this plant cell?

?

7. What is the organelle/ structure around this animal cell?

Time to check your answers:

Did you get them all correct?

1. Chloroplasts

2. Nucleus

3. Mitochondrion

4. Endoplasmic Reticulum

5. Vacuole

6. Cell Wall

7. Cell Membrane

Speaking of cell membranes, let’s look at some of the things that cell membranes

doCell Membranes

surround and protect each

and every cell, so they’re kind of important

1.2.

3. Cell Membranes are Semi-Permeable

• Semipermeable (pronounced Sem-i-perm-e-able) means some things can go through, but other things can’t

• For example, oxygen can go through the cell membrane easily, but large molecules can’t.

4. Cell Transport is the movement of materials across/ through cell membranes. There are two types of cell transport

5.

6. Passive cell transport means material can move without using energy

7. Active transport means material is only moved with the use of energy (ATP from

Mitochondria)

8.

9. Why should you not drink salty seawater?

• Osmosis causes water to move from a high concentration of water to a low concentration of water

• If you drink salt water then water will leave your cells to go to the low concentration of water outside the cells

10. What happens during diffusion?

Check on our gummy bears.

What to do:1. Go find your cups with the gummy bears in them.

2. Pour the water and the salt out so you can compare the sizes of the gummy bears

3. Get another gummy bear from the front of the room so you can compare

4. Fill out the chart and answer the questions about the gummy bears you have

Your gummy bears should look like this:

What to do:

Compare the sizes of the gummy bears and fill out the lab paper by drawing diagrams and answering the questions.

1. If vanilla extract (vanilla molecules mixed with water) is placed into a balloon and the balloon is inflated, will you be able to smell the vanilla outside of the balloon?

2. Why or why not?

3. If an egg (with the shell removed) is placed in fresh water, will the egg grow or shrink?

4. If an egg (with the shell removed) is placed in salt water, will the egg grow or shrink?

5. Why would the egg do what you said in questions 4 and 5?
