1. The three statements of the cell theory are All living things are made of cells ______________________, Cells are the basic unit of structure and function _____________________, and All cells come from other cells ____________________. 2. An organism that is made up of only one cell is called unicellular a(n) ____________ organism. 3. An organism that is made up of more than one cell is a multicellular _____________ organism. eukaryote 4. A ___________ cell has a nucleus and a prokaryote ____________ cell does not. 5. Inside the cytoplasm, you will find the “little organs” of organelle the cell called __________.
Match the following organelles to their function. c _____ 6. cytoplasm D _____ 7. nucleus _____ 8. cell wall B E _____ 9. cell membrane _____ 10. mitochondria H A _____ 11. ribosomes K _____ 12. lysosomes _____ 13. chloroplasts I J _____ 14. endoplasmic reticulum (ER) F _____ 15. golgi apparatus/bodies/ complex G _____ 16. vacuole A. manufactures proteins B. provides protection and structure for a plant cell C. gelatin-like substance found inside the cell where most of the work done by the cell takes place D. stores information/DNA for the cell E. semi-permeable layer that helps to control what enters and exits the cell F. packages and stores proteins and other materials for the cell G. Stores water for cells; larger in plant cells H. breaks down sugars to make energy for the cell I. converts light into sugar/food for the plant cell to use J. a maze of passageways that help to move material around the cell K. breaks down and destroys unwanted material inside of the cell
19. When cells break down glucose to get energy, this respiration is known as _________. chloroplast 20. Photosynthesis occurs in the ________, mitochondria and cellular respiration occurs in the ______. sugar 21. The raw materials for respiration are _____ oxygen and ______ 22. The products of respiration are _______, carbon dioxide Energy water ____ and ______. Diffusion 23. _____ is the process by which molecules spread out. Osmosis 24. _____ is the diffusion of water through a membrane. 25. The two types of active transport are transport proteins engulfing ___________ and ________.
26. When DNA condenses (winds up) around chromosome proteins, it forms a ____________. 27. The cell cycle is broken down into 3 main interphase mitosis periods (list in order): ______, cytokinesis and ______. 28. The longest part of the cell cycle is interphase _______ and the shortest part is cytokinesis ______. interphase 29. During ______, the DNA inside of the cell makes a copy of itself. Mitosis 30. ____ is the stage of the cell cycle in which the nucleus divides. 31. The 4 stages of mitosis IN ORDER are prophase metaphase ________, _________, anaphase telophase ________, and __________.
32. The two types of passive transport are diffusion osmosis ________ and ______. anaphase 33. In the _________ stage of mitosis, the chromosomes are pulled apart toward opposite ends of the cell. metaphase 34. In the ______ stage of mitosis, the chromosomes line up in the center of the cell. prophase 35. In the ________ stage of mitosis, DNA winds up into chromosomes and the nuclear membrane disintegrates. telophase 36. In the ______ stage of mitosis, the cell has two nuclei. 37. The period of the cell cycle that comes after mitosis is cytokinesis _______. 38. The cell grows and develops during the interphase _______ part of the cell cycle.
Label the plant cell with the following organelles: • cytoplasm, cell wall, cell membrane, vacuole, nucleus, vesicle, mitochondria, chloroplasts, ribosomes, ER, golgi apparatus Cell wall cytoplasm Cell Membrane Vacuole Nucleus Chloplast ER vesicle Ribisomes Mitochondria Golgi bodies
39. The two ways cells can get energy without using alcohol fermentaion oxygen are ___________ and Lactic acid fermentation _____________. (causes muscle cramps!) Photosynthesis 40. __________ is the opposite process of respiration. mutation 41. Cancer begins with the _______ of the DNA. A tumor 42. ______ is a mass of abnormal cells that develop when cancerous cells divide. 43. The three common ways of treating cancer are surgery radiation ______, _______ and _________. chemotherapy 44. The factors the lead to the development of cancer are 1)________, 2) ___________ family history chemical exposure 3) ________ and 4) ___________ radiation UV light 45. Explain how cancer is different from the normal cell cycle. Cancer is uncontrolled cell division.
