***New Week: Start on new side of sheet***

List two things you already know about cells.

CELL THEORY Prokaryotic Cells vs. Eukaryotic Cells

Objectives:

1. List the parts of the cell theory

2. Describe the organization of biological systems

3. Compare/contrast prokaryotic & eukaryotic cells

Cell Theory

1. All living things are made of

cells.

2. Cells are the basic units of life.

3. New cells are produced from

existing cells. (mitosis)

Cell Discovery (Know these people!)

• Robert Hooke (1665) • Discovered the cell• Looked at cork under a microscope• Said “ looks like a cell”

• Anton van Leeuwenhoek (1674)• 1st to view living cell • Observed pond water under a microscope

Organization of Living Things

Living:

Cells Tissue Organ Organ System Organism

Organism

Characteristic of Living Things

1. Made up of cells

2. Reproduce

3. Based on a universal genetic

code

4. Grow and develop

Characteristics of Living Things

5. Obtain and use materials andenergy

6. Respond to their environment

7. Homeostasis = maintain a stable environment

8. Change over time

Prokaryotic Cells• Small and Simple• Has a cell membrane• NO membrane bound organelles• NO nucleus• Genetic Material is found in cytoplasm• Only BACTERIA cells

Eukaryotic Cells

• Larger and more complex• Has a cell membrane• HAVE membrane bound organelles (Ex: chloroplasts &

mitochondria)• HAS a nucleus w/ genetic material inside• Protist, Fungi, Plant AND Animal cells

Prokaryotic vs Eukaryotic Cells

0.1-10 µm (= smaller)10-100 µm (= larger)

Summary

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. )

Prokaryotic Vs. Eukaryotic Venn Diagram

Instructions: We are going to compare and contrast prokaryotic & eukaryotic cells.

1. Turn to the next available blank sheet of paper in your notebook

2. Draw a Venn Diagram (2 circles that overlap)

3. Label one circle Prokaryotic & the other Eukaryotic
