Vocabulary: Organism, Unicellular, Multicellular Name: Score: /50 Date: Video 1 INTRO Video 2 INTRO Organization of Life Brace Map Period: Directions: Please read pages 56-60 and answer the questions that are on this paper. Cells: Starting Out Small 1. What is a cell? Cells are the basic unit of life. Cells are a membrane bound structure with everything needed for life. 2. How many cells do all living things have? All organisms have at least one cell. The human organism has at least 100 trillion cells. (see page 56 at bottom). 3. How are chickens formed? From 1 cell from mom (hen) and one cell from dad (rooster). They make the 1st cell that begins as a tiny white dot inside the yolk. 4. On your own, name three different kinds of cells that are in the human body. Humans have over 200 different kinds of cells and at least 100 trillion total. Three types could include bone cells, blood cells, and skin cells. 4 Types of Tissue Tissues: Cells Working in Teams 5. What is a tissue? A tissue is a group of cells working together to perform a specific job. 6. Give three examples of tissues that are formed from the three types of cells pictured in figure three on page 57. Three examples of tissues formed by cells include fat, blood, muscle. Organs: Teams Working Together 7. When two or more Tissues work together to perform specific job, the group of tissues is called an organ . 8. Give examples of four kinds of organs within the human body. stomach, heart, lungs, skin 9. What are three examples of organs in plants? Leaves, Stems and Roots Just a note… Did you know that in your lifetime you will shed about 40 pounds of skin? 11.Why is skin considered an organ? Skin is considered and organ because it is made of more than one kind of tissue working together to support the organ. Read Page Organ Systems: A Great Combination 12. Organs work together in groups to perform particular jobs. These groups are 58 called organ systems. See page 524 -526 of text book. 13. Explain how organs belonging to an organ system depend upon each other. Every cell, tissue, organ, and system of a complex and multi –celled organism like the human is needed to support life. (i.e. pancreas and diabetes, heart and o2, rbc (sickle cell anemia) for carrying o2 etc. platelets(hemophilia) for clogging blood.) See Web 14. Turn to the people in your row and quickly brainstorm to try and name the 10 major organ systems of the body. The group to name the most will earn a treat. (Hint: The respiratory system is one of them.) See page 524 -525. 1. 6. 2. 7. 3. 8. 4. 9. 5. 10. Organisms: Independent Living 15. What is an organism? Anything that can live on its own and carry out life processes is an organism. 16. True / False (Circle Correct Answer) All organisms are made up of at least 1 cell. 17. Explain at least 3 differences between a multi-celled organism and a 1- celled organism. a. Multi can get bigger b. Uni can live as just one cell. c. Multi are more complex and have the 5 levels. 18. On your own, name three different living organisms. a. cow b. dog c. sponge (porifera) Review: The answers to this section will come from your understanding of what you just read. (You may work with your table partner on these questions) 19. Compare the five levels of organization of living things to a city. What could the cells of the city be? What could the tissues be and so on….. (compare all 5 levels). 20. List the five levels of organization of living things from simple to most complex. The simplest level is done for you. 21.
