Lab # 4 Cell Structure Presented by Kami

What are the building blocks from which all parts of the human body are formed? cells How do you prepare a wet mount slide of cells lining the inside of your cheek? 1)Gently scrape the inside of your cheek with a toothpick, 2)Place cells on slide, 3)Cover the slide with a coverslip. If she was making a stained slide of her cheek cells she would add a drop of dye and then cover the liquid with a coverslip.

This student is looking for what? Cheek cell

This picture, taken at a higher magnification, shows the same cells stained with methylene blue solution to show clearly the nuclei and cell walls. The cell in the middle which appears to have two nuclei is most likely two transparent cells stacked on top of each other. This picture shows several epithelial tissue cells from a human cheek. The cell walls and nuclei are clearly visible. The cells are suspended in a fluid matrix of saliva.

1. Cell membrane 2. nuclear envelope 4. Endoplasmic Reticulum 5. Golgi body 6. Golgi body 7. Centriole 8. Lysosome 9. Mitochondrion 10. Vessicles 11. Chromatin 12. Nucleolus 13. Nucleus 19. "Dots in ER, Ribosomes" What are the structures of the cell? 1. 2.

Cell structures and function Cell membrane centrosome chromatin Cilia Cytoplasm ER Golgi body Iysosome Mitochondrion Nuclear envelope Nucleolus Nucleus Ribosome What are the names of the organelle structures? Outside boundary of the cell Contains centrioles Loosely coiled fibers containing protein & DNA in nucleus Movement Occupies space between cell membrane and nucleus Protein synthesis in RER, lipid and cholesterol synthesis in SER Packaging and secretion (UPS guy) Contains digestive enzyme ( garbage man of the cell) Location of energy release from food molecules (powerhouse) Separates nuclear contents from the cytoplasm Dense body of RNA within nucleus Contains chromatin and nucleolus Small RNA-containing particles for the synthesis of proteins
