Dive into the world of cell division through mitosis. Understand its purpose, process, phases, and significance in creating diverse life forms. Explore the division of prokaryotic and eukaryotic cells. Study diagrams and microscopic images to unravel the intricacies of mitosis phases.
E N D
Objective: • Understand the purpose of mitosis • Understand the process of mitosis • Explain the sequence and events of each phase
What are the two types of cells? • Eukaryotic • Prokaryotic
What are prokaryotic cells? • Simple cells • Few internal structures • No membrane bound organelles • One-celled organisms, Bacteria
Examples of prokaryotic cell: Bacteria Cells
What are eukaryotic cells? • Cells that contain organelles surrounded by membranes • Most living organisms
Examples of eukaryotic cells: Plant Cells Animal Cells Human Cells Human Cells
Plant Cell (Tomato) Animal Cell (tiger)
How do prokaryotic cells divide? • Binary Fission • (A fancy name that scientists use to impress their girlfriends or boyfriends. A process where one prokaryotic cell becomes two.)
How do eukaryotic cells divide? • Mitosis!
What is mitosis? • (How eukaryotic cells divide.) • A continuous process of four phases that results in the division of the nucleus. Making more cells!
Why do we care? • Once upon a time we were all one little cell. • Because of mitosis we are now made of trillions of cells. • This applies to animals too!
The 4 Phases of Mitosis: • Prophase • Metaphase • Anaphase • Telophase
What about Interphase? • Interphase is the resting period between cell division.
Why do we study diagramsfirst? • Easy to identify structures • Clear • Simple
Why do should we view microscopicimages also? • To see the real deal! • To reveal greater complexities.

Are the cells really pink and purple? • Nope, they are stained so that we can see the organelles better.
