Warm Up Monday, September 16, 2013 ***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 and energy 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 µm (= smaller) 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
