1. Unifying Characteristics of Life- The Cell Review

2. What is the role of the cell membrane?
separates the cell from external environment; regulates what enters and exits

3. Why is the cell membrane referred to as selectively permeable?
It only allows some substances to enter & exit the cell

4. What is the job of the rough ER?
modifies and then packages proteins into vesicles; Abundant in cells that produce a large amount of protein for export

5. What makes up the cell membrane?
A phospholipid bilayer containing cholesterol, carbohydrates, and proteins

6. What is the function of lysosomes?
clean up crews of the cell; contain powerful enzymes

7. What is the purpose of the cytoskeleton?
shape and organization, transport

8. What are cilia and flagella?
cilia move materials past the cell and flagella enable cells to move

9. What organelle is involved in the synthesis of steroids in glands and the breakdown of toxins?
Smooth ER

10. Cell membrane, DNA, ribosomes, and cytoplasm
Which Four structures are common to both prokaryotic and eukaryotic cells?
Cell membrane, DNA, ribosomes, and cytoplasm

11. What are Microfilaments and microtubules?
Filaments-support and movement Tubules- maintain shape

12. What organelle converts sunlight, carbon dioxide, and water into sugars?
chloroplasts

13. If a cell requires a large amount of energy, what organelle would it have a lot of?
mitochondria

14. What is the function of a ribosome?
Site of protein synthesis

15. What is the function of the nucleus of a cell?
control center; contains the hereditary information of DNA

16. What is the main function of the cell wall?
To protect and support cells such as plants, fungi, and bacteria

17. What are the differences between plant & animal cells?
  Plant cells have chloroplasts and a cell wall, have a rectangular shape, and have one large central vacuole

18. What is the function of the Golgi Apparatus ?
Final modification and packaging of proteins for release from the cell

19. storage centers of cells; water, food, or wastes
What are Vacuoles?
storage centers of cells; water, food, or wastes

20. What are Vesicles?
Membranous sacs that transport materials throughout the cell

21. What is the function of the Mitochondria?
  converts chemical energy in food into useable energy

22. What are the differences between prokaryotes & eukaryotes?
Prokaryotes do not have a nucleus or membrane bound organelles; they have circular DNA while eukaryotes have linear DNA.

23. How are prokaryotic cells and eukaryotic cells similar?
Both contain DNA, cell membrane, cytoplasm, and ribosomes

24. How are plant and animal cells similar?
Both contain cell membranes, DNA, ribosomes, cytoplasm, and common organelles
