Question #1: Describe the events leading to he discvery of the cell theory.
The discovery of the cell theory started when Robert Hooke (1665) looked at a cork under a microscope and saw little boxes, called cells. Then in 1830 Matthias Schleiden looked at plants under a microscope, and they had cells. Then Theodor Schwann found out that animals are made of cells. Rudolf Virchow thought that cells would form new cells, and every cell came from a cell, hence the cell theory.
Question #2: Identify the role of the nucleus in hte life of a cell.
The nucleus is in the center of the cell, and it lets material leave and enter it. The nucleus contains DNA. The nucleus is like the brain of the cell.
Question #3: Compare and contrast the differences between plant and animal cells.
Plant cells have the cell wall of adjacent cell, the chloroplast, the central vacuole, and the cell wall. The Golgi body in the plant cell is smaller than the animal cell. The animal cell has the lysosome, and the plant cell doesn't.
Question #4: Explain how a cell is like your school or town. What is the nucleus of your town? The mitochondria?
If our town was a plant cell, the nucleus would be the school district and the Sheriff's Office. The central vacuole would be the Fire House because it is so big. The Golgi bodies would be the Court House, it stores most of the information. the Cell wall would be the mine, it is always there and huge. THe mitochondrion would be Raine's store, it releases energy when needed.
Question #5: Think Critically: How is the cell of a one-celled organism different from the cell in many-celled organisms?
A one-celled organism dependes on itself to provide life, but a many-celled organism depends on other cells to provide life.
