Warm-Up: 4 minutes Who first named a “cell” by looking at cork? Work with your partner to answer the following questions (but each of you write down in your spiral) Who first named a “cell” by looking at cork? What are the 3 parts to the cell theory?

Story time: Cells In 1665 Robert Hooke used a microscope to look at a thin slice of cork

What Hooke Saw Under the microscope, the cork seemed to be made of empty chambers Hooke called these chambers “cells”

The Cell Theory All living things are made up of cells - Unicellular (uni = 1) - Multicellular (multi = 1+) Cells are the most basic unit of life New cells are produced from existing cells

Make observations about each picture. Which could be used to describe “complex?” Which could be used to describe “simple?”

Life can be divided into 2 groups based on complexity Life can be divided into 2 groups based on complexity. Decide if the organisms below are more complex like the house or more simple like the shack. Borrelia burgdoreri Loxodonta africana Staphylococcus aureus Homo sapiens Listeria monocytogenes Sequoiadendron giganteum

There are 2 types of cells EUKARYOTE PROKARYOTE

Objective To compare and contrast a eukaryotic cell to a prokaryotic cell in a Venn Diagram. Read the passages about both types of cells. Underline/highlight/make notes of the important characteristics of each to use when you make your Venn Diagram.

What does Prokaryote (pro-KAR-ee-othts) mean? Pro = before karyon = nucleus Do not contain a nucleus; DNA found in the cytoplasm

Example of Prokaryote: Bacteria There are many different types of bacteria Some can cause disease Some recycle important natural resources through decomposition Some bacteria is used to make food, such as milk products

Actual Prokaryotic Cells

What does Eukaryotes (yoo-KAR-ee-ohts) mean? Eu = true karyon = nucleus Does contain a nucleus (where DNA is found) Has membrane-bound organelles Examples: Animals, plants, fungi, and protists

Organelles Known as “little organs” Definition: Specialized structures with individualized jobs to carry out the functions of the eukaryote cell. EXAMPLE: Nucleus Cell Membrane Cytosplasm

Prokaryotes Eukaryotes COMPLETE THE VENN DIAGRAM BELOW! Prokaryotes Eukaryotes Prokaryotes Both Eukaryotes Larger Smaller type of cell Include bacteria Found in humans ContainDNA Lack nucleus Nucleus microscopic Lack organelles Contain Organelles outer membrane Complex Mostly unicellular organisms Simple Mostly mutlicellular organisms

Exit Ticket Answer the following questions by listing either prokaryote or eukaryote: Which type of cell does NOT contain a nucleus? Which type of cell is larger? Which type of cell do bacteria have? Which type of cell has complex organelles?
