Cell Structure Wrap-up and Review
2
Writing Assignment

• Get out your writing assignment outline.
• Switch with a partner for 3-4 minutes and check
  for the following
• Cell analogy (ex The cell is like a school.)
• 5 cell organelles and their function
• 5 analogous structures, their functions and how
  they relate to a specific cell organelle.

3
Example Outline

• The cell is like a school. (Main idea)
• Nucleus control center of the cell
• Principal command center for the school
  instructs workers on how to do their jobs
• Endoplasmic reticulum transport of fats and
  proteins throughout the cell how
  molecules/substances get from place to place
• Hallways how students move through the
  building/are transported from class to class

4
Converting your outline to paragraph form

• Use your outline to guide your writing.
• Outline Nucleus Control center
• Principal command of schools function
• Sentence The principal controls and manages the
  schools functions much like the nucleus controls
  the cells functions and processes.

5
Writing wrap-up

• Use the next few minutes to begin constructing
  the rough draft for your writing assignment.
• Your rough draft is due tomorrow before you take
  your quiz.
• Final draft is due on Friday.

Enzymes -- test-taking review

• If you think the following statement is
• True Pat your head
• False Rub your belly
• Not sure Do both
• Enzymes are proteins.

8
TRUE! (Pat your head!)

• TRUE, enzymes are proteins!

9
More test-taking with enzymes

• If you think the following statement is
• True Show spirit fingers
• False Cross your fingers.
• Enzymes speed up the rate of chemical reactions
  by raising the activation energy.

10
FALSE! (Cross your fingers.)

• The statement was false!
• True statement Enzymes speed up the rate of
  chemical reactions by LOWERING the activation
  energy.

Cell Structure Review

• 1. What is the basic unit of life? CELLS
• 2. What is the nucleus?
• Organelle located in the center of the cell
• 3. What is the function of the nucleus? (What
  does it do?)
• Control center of the cell
• Stores DNA

12
Cell Structure Review

• 4. What are two organelles found in plant cells
  but not in animals cells?
• Chloroplasts (chlorophyll)
• Cell Wall
• 5. Which organelle is the powerhouse of the
  cell? MITOCHONDRIA
• 6. The town hall of a city is similar to which
  organelle in an animal cell?
• NUCLEUS

13

• 7. What is the MAIN difference between
  prokaryotic and eukaryotic cells?
• Prokaryotes NO NUCLEUS
• Eukaryotes true nucleus
• 8. List two things that ALL CELLS have in common.
• Cell membrane and cytoplasm
• 9. List two functions of the cell membrane.
• 1. Surrounds the cell
• 2. Controls what goes in/out of the cell
• 10. What is the function of a lysosome?
• THINK LYSOL
