16. What do all of these living organisms have in common?

17. ALL living organisms are made up of cells!!!

18. When you approach a building from a distance, you first notice the shape of the whole building.

19. As you draw nearer to the building, you become aware of its different parts: walls, windows, doors, staircases, downspouts, and so forth.

20. When you are only a few feet away, you realize that the walls are made up of bricks. Each brick forms part of the structure of the entire building

21. If you were to look at one of those bricks up close you would see its structure.

22. Animals and plants have an overall shape or structure, as well as different components parts.

23. But when you examine their structure more closely, you see that they are made up of smaller units.

24. These tiny “bricks” that make up the structure of living things are called cells. Cells are too small to be seen with the naked eye, but are clearly visible under a microscope

25. CELL THEORY All living organisms are made up of cells. All living organisms are made up of cells. Cells are the basic unit of structure and function in an organism. Cells are the basic unit of structure and function in an organism. All cells arise from other cells. All cells arise from other cells.

26. Cell Theory What is a theory? A theory is an explanation of a set of observations or events based upon proven hypotheses and verified multiple times by different people. What is a theory? A theory is an explanation of a set of observations or events based upon proven hypotheses and verified multiple times by different people. So if we were to apply this to cells, we would expect that any living organism we looked at under the microscope would be composed of one or more cells! So if we were to apply this to cells, we would expect that any living organism we looked at under the microscope would be composed of one or more cells!

27. Cell Theory What do we mean by structure and function in the second part of the theory? What do we mean by structure and function in the second part of the theory? Cells are the basic unit of structure and function in an organism. Cells are the basic unit of structure and function in an organism. Structure is what we see when we look at something – a buildings structures are the walls, windows, doors, etc. Structure is what we see when we look at something – a buildings structures are the walls, windows, doors, etc. Function is the purpose for which something exists. A cells function is to survive! Function is the purpose for which something exists. A cells function is to survive!

28. Cell Theory All cells arise from other cells means that cells do not appear from no where, but come from other cells. All cells arise from other cells means that cells do not appear from no where, but come from other cells.

29. Cells can be classified into 2 groups. Eukaryotic Cells Have a defined nucleus. Found in organisms that are made up of many cells. Animals Animals Plants Plants Prokaryotic Cells

31. Animal Cell Plant Cell

32. Let’s look at some actual plant and animal cells!

33. Plant Cells

34. Animal Cells

35. Cells can be classified into 2 groups. Eukaryotic Cells Prokaryotic Cells No structured nucleus Exist as single-celled organisms Bacteria Bacteria

36. Prokaryotic Cell

37. How would you classify this cell?

38. How about this cell?

39. What about this one???
