•Anton van Leeuwenhoek (1674)- First to view living cell; looked at pond water under a microscope.

2. Robert Hooke (1665) observed cork using a compound microscope and named the structures he saw “cells”.

1. Schleiden (circa 1838) All plants are made of
cells!
Onion skin cells

Three part theory about cells1. All living things are made of cells
2. The cell is the basic structural and functional unit of life. (basic unit of life)
3. All cells come from pre-existing cells.

1. Have NO Nucleus
2. NO Membrane bound organelles (have no organelles surrounded by membranes)
3. They are unicellular cells (single-celled)
4. Example is bacteria

1. They have a nucleus.
2.They have membrane bound organelles(organelles
that perform specific functions)
3 They are multicellular cells(many cells)
4. Examples are plants , animals , fungi, and protists

Instructions: We are going to compare and contrast prokaryotic & eukaryotic cells 1.Turn to the next available blank sheet of paper in your notebook2.Draw a Venn Diagram (2 circles that overlap)3. Label one circle Prokaryotic & the other Eukaryotic

Draw a line in your notes to complete your summary. To get credit it needs to be 3-5 complete sentences.
You will need to complete this summary at home tonight. (This is after every day of notes. )
