Directions: Before the video starts, read the questions. If you know any of the answers, fill them in the blank provided before each sentence. As the video plays, confirm your answers and fill in the ones you didn’t know by writing the word(s) in the balk space in the sentence. Each answer must be used one time. The questions are in the same order as the video. Questions 1. All plants and animals are made of CELLS 2. Humans are more like animals such as rabbits than plants because WE ARE MADE OF ANIMAL CELLS 3. Humans are made of 100 TRILLION (number) cells. 4. Organisms like rabbits have many different kinds of cells to do different JOBS 5. Cells are LIKE bricks because they are piled up to make something, but they are DIFFERENT because cells are ALIVE and bricks are not. 6. GROWTH is when more cells are made than die. Alive or not? (Write the correct classification next to each item shown in the video.) Part 1 Part 2 LIVING family NON-LIVING potato NON-LIVING volcano NON-LIVING potato chips NON-LIVING sponge cake NON-LIVING gym socks LIVING sea sponge Consider the Following: How is a cell like a room in a house? 7. A room’s wall is like a CELL WALL or CELL MEMBRANE because it surrounds the cell 8. A table in a room is like a NUCLEUS 9. A fireplace is like a MITOCHONDRIA because it provides energy 10. MITOSIS is the process of one cell becoming two cells 11. GENES are the road map for cells and tell the cells what to do 12. SKIN is our body’s fastest growing organ because we shed millions of these cells every day 13. Genes are made of DNA 14. Humans have 23 pairs of chromosomes (46 total) 15. EGG Name one large single cell that is very easy to see. 16. Red blood cells are red because the IRON in the cell mixes with the OXYGEN we breathe in. 17. WHITE BLOOD CELLS attack viruses to keep us from getting sick. 18. OSMOSIS is how cells exchange chemicals with the environment and other cells. 19. The only type of human cell that is never replaced is NERVE CELL 20. One of the characteristics of being ALIVE is being made of cells.
