Page: 18 Date: 9/21 Title: Prokaryote Cells vs. Eukaryote Cells Essential Question: How do I compare prokaryotic and eukaryotic cells? GLUE IN YOUR SKELETON NOTES

EQ: HOW DO I COMPARE CELLULAR STRUCTURES AND THEIR FUNCTIONS IN PROKARYOTIC AND EUKARYOTIC CELLS

BEFORE WE CAN MOVE FORWARD, YOU NEED TO KNOW. . . • All organisms (living things) are made of cells • Most of the organisms you are familiar with are multicellular-made up of many cells. • However, some organisms can be unicellularmade up of only one cell. Its entire body is just

CELLS FALL INTO ONE OF TWO CATEGORIES… • Prokaryotes (prokaryotic) or • Eukaryotes (eukaryotic) And that is it! Every organism on the planet can be put into one of these two categories, including you!

Pro means NO!

PROKARYOTES: • unicellular microorganisms • lack a distinct nucleus • lack membrane-bound organelles • always bacteria!!! • very simple and small

PROKARYOTES:

Eu means True

EUKARYOTES: • unicellular or multicellular organisms • have a nucleus • have membrane-bound organelles • LARGER and more complex (have more stuff inside) • Examples: animals, plants, fungi and protists • NEVER BACTERIA!!!!

Or ga n ell es EUKARYOTES: Like the organs in your body, each organelle in the cell performs a specific function that helps the cell maintain homeostasis: a state of balance.

EUKARYOTES:

Prokaryotes are much smaller than Eukaryotes Prokaryote (Bacteria) Eukaryote (Animal Cell)

Prokaryote: • Lacks Nucleus • Organelles Lack Membranes • DNA is free floating • Always unicellular • Always bacteria • Smaller than Eukaryote • Reproduction is asexual (exact copies/clones) Eukaryote: • • Has Nucleus Organelles have Membranes DNA is in the Nucleus Can be unicellular or multicellular Plants, Animals, Fungi, Protists Much Larger than Prokaryote Reproduction can be asexual (clones) or sexual (variations)
