Day 11 Microscopes and Cheek Cells
Cell Quiz
For your quiz you will be given a picture of an unlabeled cell and you will have to label all of its organelles. Under the organelle you will have to say its function in the cell.
Answer Key:
Review of Cell Organelles
Golgi Apparatus - Packages, labels, and ships anything made in the cell
Nucleus - Where genetic information is stored (DNA)
Nucleolus - Where ribosomes are made
Plasma Membrane - The membrane around a cell (phospholipid bilayer)
Mitochondria - Where ATP (cell energy is made)
Endoplasmic Reticulum
Smooth ER - Makes lipids and also detoxifies things
Rough ER - The location where proteins are made
Ribosomes - Makes proteins
Cytoplasm - The space in the cell between the membrane and the nucleus
Cytoskeleton - Holds the structure of the cell
Vacuole - Cell storage
Vesicle - Cell transport
Lysosome - A vesicle filled with digestive enzymes for breaking things down
Centriole - For cell division
Chloroplast - Does photosynthesis
Cell Wall - Around the membrane for protection
Flagella - A tailed used for movement
Cilia - Hair like structures for movement
Intro to microscopes
-The parts of a microscope and how to use them.
Going to the Lab for the Microscope Lab
We will be practicing using the microscope by looking at a few prepared slides.
-I want you to draw what you see in Four prepared slides
-Once you have done that together we are going to go through the lab on slide staining
-You will be scraping the inside of your cheek in order to obtain some cheek cells. We will then use those to stain and prepare a slide.
-Once you have made your slide use the microscope to locate an individual cell. Once you have located one you will draw it and identify any organelles that you can find.
-The organelles are hard to find so it is okay if you can only find a few. There are many that are too small to see.
Cell-fie
Once you have a good image of your own cheek cells under the microscope you can press your cellphone camera to the ocular and take a picture
Pond Organisms
-We are going to take a walk to the park and collect some stream water
-We will bring the water back to the lab and view it under a microscope
-Lets see what kind of microscopic organisms we can find
If you find a single celled protist in your water sample, try to identify some of its organelles
After we have viewed our water samples we will present our cell cities
