Questions - 20 points - Click here for a printable version!
Copy and answer the following questions in complete sentences.
1. Describe the difference between prokaryotic and eukaryotic cells.
2. What is the difference between a cell wall and cell membrane?
3. Why do plants need cells with cell walls?
4. Every cell needs a membrane. Why?
5. What would be the negative effects of a cell not having lysosomes?
6. Predict whether skin cells or muscle cells have more mitochondria. Explain how you arrived at your prediction.
7. Why are digestive enzymes in a cell enclosed in a membrane-bound organelle?
8. If you were given a slide containing living cells, how would you identify the cells as either plant or animal?
9. What would happen if the nucleus of a cell were damaged?
10. What are the benefits of being multicellular?
Science Fiction Story - 20 points
Write a science fiction story about an animal whose cells are invaded by chloroplasts. Describe how that animal's life processes would be affected and how that animal would use this unusal occurrence to its advantage. You may use any multicellular animal that you like.
Cell Mathematics - 15 points - Click here for a printable version!
Rewrite each statement, filling in the answers to make the statements correct.
-
1. A hen's egg is about 50 mm in diameter. A human egg is about
0.
14 mm in diameter. What is the difference in size between the hen's egg
and the human egg? _____________________mm
- Edible Cell - There are many web sites that you can
look at to get ideas.
- Cell City - To build a cell city, you would compare
buildings and streets in a city to the parts of a cell and build or
draw a model.
- 3-D Model - You can use any type of craft materials to make your cell (styrafoam balls, pipe cleaners, paint, etc.)
2. A drop of blood contains five million red blood cells and ten thousand white blood cells. How many TIMES more red blood cells are there than white blood cells? _________________ times
3. The nucleus of a cell is about 0.000625 cm in diameter. What is the diameter of this nucleus expressed in millimeters? _____________mm
4. A biologist notices that a petri dish is becoming covered with colonies of bacteria. The doubling rate of the bacterial colonies is one day. At the end of 30 days, the plate is covered with bacteria. When was the petri plate half-covered with bacterial colonies? _______________ day
5. A single cell reproduces by mitosis (reproduction by splitting in half). How many cells will be present at the end of the first division? __________________ At the end of the second division? __________ At the end of the fifth division? _____________ At the end of the tenth division ? _________________ At the end of the twentieth division? __________________
Identify the Cell Structures - 10 points - Click here for a printable version!
Read and copy the short poems below. Answer the question "What am I?" at the end of each poem.
1. I'm a real "powerhouse." 6. I'm a series of tubes
That's plain to see. Found throughout the cell.
I break down food I transport proteins
To release energy. And other things as well.
2. I'm strong and stiff 7. I'm full of holes,
Getting through me is tough. Flexible, and thin.
I'm found only in plants, I control what gets out
But I guess that's enough. As well as what comes in.
3. My name means "colored bodies," 8. Proteins are made here
And I contain DNA Even though I'm quite small.
I pass on traits to new cells You can find me in the cytoplasm
In a systematic way. Or attached to E.R.'s wall.
4. I'm the "brain" of the cell 9. I've been called a "storage tank"
Or so they say. By those with little taste.
I regulate activities I'm a sac filled with water,
From day to day. Food, enzymes, or waste.
5. Found only in plant cells, 10. Since I contain many enzymes,
I'm green as can be. I can digest an injured cell;
I make food for the plant And can break down a large molecule
Using the sun's energy. Into a smaller one as well.
Cell Models - 30 points
Choose either a plant or an animal cell and choose how you would like to make your model. Here are some possible ideas. Your model should be made to scale and contain the correct labels. All models must have the organelles labeled. A HEALTHY edible cell will be worth 40 points.
Puzzles - 10 points
- You can create an original puzzle (Wordsearch or Crossword) with an answer key.
- You can also go to www.quia.com,
create a trial INSTRUCTOR account and make an online cell game.
- I am only going to offer one laboratory activity. If you would like to bring in a sample of pond water stay after school to make slides and use the microscope, you can earn 15 more points. This lab will take place on Tuesday, January 31st.
