3 Station 3 5. Eukaryotic cells are divided into two types and. 6. What are the general shape of the two types of eukaryotic cells? 7. An example of a prokaryotic cell is.

4 Station 4 I m a real powerhouse That s plain to see I break down food And release energy 8. Whom am I? I m the fluid in the cell That fills in the space My main purpose is To hold organelles in place 10. Whom am I? I m strong and stiff getting through me is rough I m found only in plant cells I m what makes them so tough 9. Whom am I?

5 Station 5 I m found only in plant cells I m as green as can be I make food for the plant Using the sun s energy 11. Whom am I? I ve been called the storage tank By those with little taste I m a sack filled with water, Food, enzymes, and waste 13. Whom am I? I m full of holes Flexible and thin I control what gets out As well as what comes in 12. Whom am I?

6 Station 6 I act like a digestive system in an animal cell I contain enzymes that break down and get rid of waste And I do it quite well. 14. Whom am I? I m the brain of the cell Or so they say I regulate activities with DNA From day to day 16. Whom am I? I build proteins in the cell and in several places can be found Including the cytoplasm and on ER In cells that are square or round. 15. Whom am I?

15 Station Place the above phases in order and identify their name.

16 Station Identify each diagram as either plant or animal cell cytokinesis and what is created in the center of the two cells.

17 Station Why do cells need to create new cells? 36. List the following in order from smallest to largest. Organs, cells, tissue, organ system

18 Station What characterizes cancer cells? 38. Explain how physical and internal signals control cell growth.

19 Station Which cells have the ability to differentiate (develop) into various types of cells? 40. The two types are and.

20 Station How are adult stem cells different from embryonic stem cells? 42. All cells have the same DNA. How is this possible?

21 Station 1 1. What are the statements to the cell theory? All living things are composed of cells Cells are the basic unit of structure and function New cells come for existing cells 2. What are the two categories of cells? Prokaryotes and Eukaryotes

22 Station 2 3. List the main difference between prokaryotes and eukaryotes? Prokaryotes are smaller and DO NOT have a nucleus; Eukaryotes are more complex and have a nucleus and many other organelles 4. What are the similarities of prokaryotes and eukaryotes? Both have a cell membrane, DNA, cytoplasm, and ribosomes

23 Station 3 5. Eukaryotic cells are divided into two types and. (Plant and Animal) 6. What are the general shape of the two types of eukaryotic cells? Plant- Square/Rectangle; Animal- Round 7. An example of a prokaryotic cell is bacteria.

24 Station 4 I m a real powerhouse That s plain to see I break down food And release energy 8. Whom am I? mitochondria I m the fluid in the cell That fills in the space My main purpose is To hold organelles in place 10. Whom am I? cytoplasm I m strong and stiff getting through me is rough I m found only in plant cells I m what makes them so tough 9. Whom am I? cell wall

25 Station 5 I m found only in plant cells I m as green as can be I make food for the plant Using the sun s energy 11. Whom am I? chloroplast I m full of holes Flexible and thin I control what gets out As well as what comes in 12. Whom am I? cell membrane I ve been called the storage tank By those with little taste I m a sack filled with water, Food, enzymes, and waste 13. Whom am I? vacuole

26 Station 6 I act like a digestive system in an animal cell I contain enzymes that break down and get rid of waste And I do it quite well. 14. Whom am I? lysosome I m the brain of the cell Or so they say I regulate activities with DNA From day to day 16. Whom am I? nucleus I build proteins in the cell and in several places can be found Including the cytoplasm and on ER In cells that are square or round. 15. Whom am I? ribosome

27 Station Which organelles are found ONLY in plant cells? Chloroplasts, Central Vacuole, and Cell Walls 18. What are the two types of ER? How are they different? Rough ER (has ribosomes attached); Smooth ER (does not have ribosomes)

28 Station 8 Prokaryote/Bacteria Eukaryote (Plant) Eukaryote( Animal) 19. Identify the following cells and organelles.

Station 9 20. Which cell does NOT have a nucleus? 1 21.

29 Station Which cell does NOT have a nucleus? Which cell has chloroplasts? Which of the above has ribosomes, cell membrane, and DNA? 1-3 (All cells)

30 Station What is the main function/job of the cell membrane? Controls what can enter or leave the cell 24. What does semi-permeable mean? Allows certain things to pass and not others (think of our starch and iodine lab with the cup and plastic bag!) 25. What does homeostasis means? Maintaining constant or stable internal conditions

31 Station Identify the two types of Cellular Transport. Active and Passive Transport 27. How are they different? Active- requires energy; up/against the concentration gradient; moves particles low to high Passive-does NOT requires energy; down the concentration gradient; moves particles high to low

32 Station Identify the types of Passive Transport. Do they require Energy? Diffusion, Facilitated Diffusion, Osmosis; NO! 29. Identify the types of Active Transport. Do they require Energy? Protein Pumps, Vesicles (Endo and Exocytosis); YES!

33 Station Explain the following Osmosis states: HypOtonic- cell increases in size; water moves in Hypertonic- cell decreases in size; water moves out of the cell Isotonic- cell size remains the same; same amount of water enters/leaves the cell

34 Station What are the 3 stages of the CELL CYCLE? Identify the purpose of each and which is the longest stage. Interphase- cell growth and duplicates DNA (longest stage) Mitosis- reduction of chromosomes (DNA) and divison on nucleus Cytokinesis- splitting of cytoplasm to create 2 cells 32. What are the 4 stages of MITOSIS? Prophase, Metaphase, Anaphase, and Telophase

35 Station Place the above phases in order and identify their name. B- Interhase; E- Prophase; C- Metaphase; A- Anaphase; D- Telophase; F- Cytokinesis

36 Station Identify each diagram as either plant or animal cell cytokinesis and what is created in the center of the two cells. Animal- Cleavage Furrow Plant- Cell Plate

37 Station Why do cells need to create new cells? Reproduction, Replacement, Growth, Repair 36. List the following in order from smallest to largest. Organs, cells, tissue, organ system Cells, tissue, organ, organ system

38 Station What characterizes cancer cells? Uncontrollable cell growth (do not recognize stop signals) 38. Explain how physical and internal signals control cell growth. Physical- cells will stop division when it comes in contact with other cells Internal- chemical signals inside the cell will control cell division

39 Station Which cells have the ability to differentiate (develop) into various types of cells? Stem Cells 40. The two types are and. Adult stem cells and embryonic stem cells

40 Station How are adult stem cells different from embryonic stem cells? Adult stem cells are found in bone marrow of organisms; embryonic stem cells are found in a mass of cells that have yet to develop into an embryo (growing baby) 42. All cells have the same DNA. How is this possible? Multicellular organisms begin as a single cell that give rise to different types of cells through cell differentiation and cell division.
