Today, your objective is to classify cells into 2 groups: 2. Eukaryotic Cells 1. Prokaryotic Cells

Your Assignment - Directions: Answer the following questions: 1. What is a prokaryotic cell? 2. What is an eukaryotic cell? 3. What is an organelle? 4. On slide 35, draw an animal and a plant cell, draw the organelles and label them. 5. On a Venn Diagram, compare and contrast an prokaryotic cell and a eukaryotic cell. 6. Complete the quiz and grade it.

ALL living organisms are made up of cells!!!

Review THE CELL THEORY

THE CELL THEORY

THE CELL THEORY All living organisms are made up of cells. .

THE CELL THEORY All living organisms are made up of cells. Cells are the basic unit of structure and function in an organism.

THE CELL THEORY All living organisms are made up of cells. Cells are the basic unit of structure and function in an organism. All cells arise from other cells.

Find the chloroplast below.

True or False? A chloroplast is an organelle in the plant cell.

TRUE! A chloroplast is an organelle in the plant cell. An organelle is any of a number of organized or specialized structures within a living cell. A chloroplast is an organelle in a plant cell. It is the site where photosynthesis happens.

First, let’s look at terms a little closer! Now what is the difference between a prokaryotic cell and a eukaryotic cell? First, let’s look at terms a little closer!

Prokaryotic before nucleus Eukaryotic true nucleus

Write the words in yellow for your definition. Prokaryotic Cells Write the words in yellow for your definition. First cells to evolve NO nucleus, DNA is free floating NO membrane bound organelles (just ribosomes) ALL are unicellular Smaller than eukaryotic cells Smaller and simpler than eukaryotic cells DNA – single strand and circular Ex: ALL Bacteria 29

Write the words in yellow for your definition. Eukaryotic Cells Write the words in yellow for your definition. Has a nucleus (DNA inside) Bigger and more complex than prokaryotes Have membrane bound Organelles (golgi, ER, lysosomes…etc) DNA – double-stranded and forms chromosomes (highly organized) Can be uni- OR multicellular organisms Ex: animals, plants, fungi

Eukaryotic Cells – What is similar and different about the two cells below? Draw your cells on your paper and label them. Animal Cell Plant Cell

Let’s look at some actual plant and animal cells!

Plant Cells

Animal Cells

How would you classify this cell How would you classify this cell? This is a bacterial cell, it is a prokaryotic cell.

How about this cell? This is a bacterial cell.
