Exploring Life - Honors Biology Chapter 6 Cells

When you click Submit (at the bottom of this web page) it will save your work on the server for me. If you get a "proxy error" hit -refresh- until you get a "Thanks"

You might want to actually write your answers in Word (so you can spell check them) and then cut-and-paste into the boxes. That way, if the computer misplaces your work you can just re-paste the answers.

Since we may work on this over more than one day, I will keep track of what you have done. Feel free to click submit as you work to save your work to the server. 

DO NOT JUST LOOK FOR THE ANSWERS…YOU’LL MISS LOTS OF IMPORTANT STUFF. THE QUESTIONS ARE JUST TO KEEP YOU “HONEST.”

TAB OR USE THE MOUSE Between the fields....

Answer the questions as best you can. The boxes will expand as you type if you need more space. (Don't worry if it is a one word answer. The box size is standard.)

Since you will be working in groups, put all the names of the people in the group in the box. The ideal group size is 2. As an exception I will allow groups of 3. No groups of 4 or 5. If you work as a group of 3 I expect better answers. Group sizes above 3 will be penalized in the grading.

You can work on this from home once you have signed up for Successnet.

Open the Explore Life CD in a separate window.   (If you need help with that ask.)

If you have already signed up for SuccessNet, you can access the assignment that way, and also work from home (or library).

While there are questions on the CD, they provide answers, so I can't grade their questions. You will get a grade for the answers on this form!

Start with Concept 6.1 The questions proceed with the disk. Do all the activities.  Answer my questions.

Question 1:  In microns (millionth’s of a meter):

A-How big are the cells in a mushroom?

B-How big are the cells in tree bark?

C-How big are the cells in frog skin?

Question 2: Why are the nuclei in the frog skin pink?

Question 3:  A- Define hydrophobic. B-Define hydrophilic

Question 4: Why is a membrane described as a “fluid mosaic?”

Question 5: Why does Dr. G. repeat over and over “semi-permeable phospholipid bilayer with embedded proteins?”

Remember, the boxes will expand as you type if you need more space.

Question 6: Does water pass through the membrane easily?  (why or why not)

Question 7:  Based on activity 6.3 do you think N2 would be able to cross the membrane?

What about H+? What about K+? What about Cl-? What about sucrose? Provide a brief explanation for each.

Question 8: What does the Na+/K+ pump need that the other transport proteins didn’t need?

Question 9: What are the three types of transport across a cell membrane? (Do not say, bicycle, car and bus!)

Question 10: What do the prefixes endo- and exo- mean? What does the root “cytosis” mean? 

Remember, the boxes will expand as you type if you need more space.

Question 11: What parts, in activity 6.4 are common to animal and plant cells?

Question 12: Why couldn’t the insulin just diffuse across the membrane?

Question 13:  What part of the chloroplast actually absorbs the light energy?

Question 14:  Where in the mitochondria is energy made?

Question 15:  Go to the virtual textbook (Chapter 6 on the left side of the screen) and go over the section on osmosis (in Concept 6.3).

What would happen to an animal cell in hypotonic solution?

Remember, the boxes will expand as you type if you need more space.

Question 16: What would happen to an animal cell in hypertonic solution?

Isotonic solution?

Question 17:  What would happen to an animal cell in isotonic solution?

Question 18:  What would happen to a plant cell in hypotonic solution?

Question 19:  What would happen to a plant cell in hypertonic solution?

Question 20:

What would happen to a plant cell in isotonic solution?
