Task:
Objectives
Upon completion of this exercise, the student will be able to:
1. Name the parts and function of the compound light microscope.
2. Distinguish size differences between prokaryotic and eukaryotic cells.
3. Compare and contrast some generalized plant and animal cell similarities and differences including shape, visible organelles.
4. Explain the reason for staining specimens.
Comparing Plant And Animals Cells
Problem: How are plant and animal cells alike? How are they different?
Part 2 Plant Cells
1.What is the function of the chloroplast?
2.Name 3 structures found in both plant and animals cells.
3.Name 2 structures found in plant cells but not in animal cells.
4.What structure surrounds to cell membrane in plant cells and gives the cell support?
Part B- Elodea Cells
Look at the images of elodea, which is an aquarium plant. When you are looking at these cells, you should find a lot more than you found with the cheek cells, and it will resemble a green brick wall. Sketch your cells under low and high power, also paying attention to scale. The nucleus of these cells will not be visible but you should see many chloroplasts within each cell. Plant cells also have a rigid cell wall, outside the cell membrane. The Cell Wall should also be visible.
Discussion Questions
1. List the structures written below, which can be found in the following cell types.
(cell wall, cell membrane, nucleus, chloroplast, nucleoli, starch granules)
a. in a cheek cell_____________________________________________________
b. in an onion cell ______________________________________________________
c. in an Elodea cell_____________________________________________________
d. in a potato cell ____________________________________________________
2. Describe the term cytoplasmic streaming. Indicate its function, the cytoskeletal components which are responsible for the movement and the location where observed.
3. What conclusion can be drawn about the size of bacteria relative to plant or animal cells?
4. What is the purpose of using stains such as methylene blue, carmine red or iodine when viewing cells?
5. Where would expect to see more cheek cells on your slide, under high power or scanning power? Explain.
6. Write a summary statement about what you have learned from this lab
