Chapter 3 CLOZE This activity is used to test your background knowledge for the Cells, Tissues, and Organ Systems chapter in our book. On a separate sheet of paper, please number 1-50. On that sheet of paper, write the word you think that the author might have used in the text with the corresponding number. The basic units of structure and function of living things are called cells. Most cells are too small to be seen with the unaided eye. As a result, many _1 the even smaller structures 2 make up a cell 3 a mystery to scientists for 4 of years. The structures that 5 up a cell are called 6, which means tiny organs. The 7 were not revealed until 8 seventeenth century, when the first 9 were invented. In 1663, while looking 10 a thin slice of cork 11 a compound microscope, the English 12 Robert Hooke observed tiny roomlike 13. He called these structures 14. But the cells that Hooke 15 in the slice of cork 16 not alive. What Hooke saw 17 actually the outer walls of 18 plant cells. At about the 19 time, a Dutch fabric merchant 20 amateur scientist, used a simple 21 to examine materials such as 22, rainwater, and scrapings from his 23. In each material, Anton van Leeuwenhoek 24 living things. He even found 25 living things in a drop _26_ rainwater. Van Leeuwenhoek called these 27 things animalcules. The smallest of 28 organisms observed by Leeuwenhoek are 29 known as bacteria. Bacteria are 30 - celled organisms. These discoveries made 31 famous all over the world. 32 the next two hundred years, 33 and better microscopes were developed. Such 34 made it possible for _35_ German botanist Matthias Schleiden to 36 different types of plant 37. Schleiden concluded that all the 38 parts he examined were made 39 cells. One year later, the 40 zoologist Theodor Schwann made similar 41 using animal parts. About twenty 42 later, a German physician names 43 Virchow discovered that all living 44 come from other living cells. _45_ work of Schleiden, Schwann, Virchow, 46 other biologist let to the 47 of the Cell Theory, which 48 one of the cornerstones of 49 biology and is accepted by 50. The cell theory states that all living things are made of cells, cells are the basic units of structure and functions of living things, and living cells come only from other living things.
