Microscope Lab: Viewing Cells - Emily Moore | Library

 In 1665, an English scientists named Robert Hooke made a simple microscope and looked at a piece of cork, the dead cells of oak bark. Hooke observed small, box shaped structures such as those shown below. He called them cellulae (Latin for small rooms) because the box like cells of cork reminded him of the cells in which monks live at the monastery.

What did Robert Hooke call the small things he saw in the cork?

Is cork living, dead, or non living?

Describe the general shape of the cells.

Describe the general shape of the onion cells.

Looking at the magnification of 100x, what parts of the cell can you see?

Is this a prokaryote or eukaryote?

What organelle will indicate whether it is a pro or eukaryote?

Why do onion cells not have chloroplasts?

Label the nucleus and cell wall in the picture.

Is the cheek cell prokaryote or eukaryote?

Is the cheek cell a plant or animal cell?

Identify one cell structure visible in the 100x picture.

Why do you think these cells have to be stained blue?

What is the benefit of the flat shape of these cells?

The Cheek Cells. Label the nucleus and the cell membrane in the picture.

Is this a prokaryote or eukaryote?

Is this a plant or animal cell?

What cell structures are visible in the 400x picture of Elodea?

Describe the basic shape of these cells.

Elodea Leaf. Label the Chloroplast, Cell Wall, and any other VISIBLE cell structures.

During the late 1600s, Dutch scientist Anton van Leeuwenhoek, inspired by a book written by Robert Hooke, designed his own microscope. To his surprise he saw living organisms in pond water. Watch at least 20 seconds of this live microscope video of pond water then answer the questions. (Ignore the annoying music)

Watch about 20 seconds of the video above. Are thethings you see in the pond water living or non living?

Explain your answer for question 21.
