List the function of each organelle GREEN TEST Nucleus Endoplasmic reticulum Cell membrane RED TEST mitochondria Vacuole Cell wall

Things to find out about cells What shape do most cells have? How many nuclear membrane layers? Why? What produces energy in a cell? How does water get into a cell? How does CO2 get out of a cell? What does a nucleus do? What does the endoplasmic reticulum do? Look like?

White Board Answers Group 1: Questions 1 & 6 Group 2: Questions 2 & 4

Cell history Leeuenhoek Hooke Schwann Schleidan Contempories; 1730’s German sci; credited w/ the idea of cell theory; the beg of the end of spontaneous generation

Beg Microscopes http://en.wikipedia.org/wiki/File:Leeuwenhoek_Microscope.png http://chem.aellumis.org/wp-content/uploads/2013/08/hookes_microscope.jpg

Two Types of Cells Prokaryotic “simple” no nucleus or membrane bound organelles most have cell wall All are bacteria of some type Eukaryotic Have nucleus* and membrane bound organelles More diverse Only plant and fungi have cell walls

Generalized Bacteria Cell

List of Organelles w/ Membranes Cell Membrane: Nucleus: nucleolus Mitochondria: Chloroplast: Vacuole:

Cell membrane

Cytomembrane Organelles Endoplasmic Reticulum (ER): rough smooth Golgi Body: Lysosomes/peroxisomes:

Generalized cell for cytomembrane system

Other Organelles Ribosomes Centrioles Cytoskeleton microtubules microfilaments

Other Organelles, cont Cytoplasm/cytosol Cell wall Cilia/flagella slime capsule Cilia/flagella
