1. Standard: SC.912.L.14.3 Compare and contrast structures of plant and animal cells. Compare and contrast the general structures of prokaryotic and eukaryotic cells.
EQ: How are prokaryotic and eukaryotic cells alike and different?
Objectives:
After studying prokaryotic and eukaryotic cells the students will be able to:
label and identify the structures of prokaryotic and eukaryotic cells.
compare and contrast the structure and function of prokaryotic and eukaryotic cells.
compare the relative sizes of prokaryotic and eukaryotic cells.
bacterial beneficial tasks
Bell work: Make a list of the importance of a cell.

2. Name a scientist that help to develop the cell theory?

3. Robert Hooke Studied cork (dead plant cells from the bark of a tree)
First identified cells (basic building blocks of all living things)

4. Matthias Schleiden and Theodor Schwann
Schleiden plants are made up of cells
Schwann  animals are made up of cells

5. What are the three components of the cell theory?

6. The Cell Theory All living things are composed of cells
Cells are the basic units of structure and function in living things
New cells are produced from existing cells

8. Cells Basic units of all living things Surrounded by a plasma membrane
Have DNA (contains genetic information)
Have cytoplasm (outside the nucleus)
Contain organelles
membrane-bound structures
small, specialized structures
each has a specific function that helps cells survive
2 groups of cells

9. Prokaryotes Smaller in size Do not have membrane-bound organelles
Have genetic material (DNA) but not surrounded by a membrane
Circular DNA floats in cytoplasm
Unicellular organisms (bacteria)
****No nucleus or nuclear membrane***
have ribosomes, cytoplasm, and cell membrane

10. Can you name some beneficial aspects of using bacteria?
Can bacteria be beneficial to humans? Yes or No? How?

11. Bacterial Beneficial tasks
1. Food productions: Yogurt and cheese
2. Cleaning – oil-eating bacteria help save beaches, other bacteria cleans up sewage.
3. Nature’s recyclers – bacteria release nutrients during decomposition.
4. Carbon and Nitrogen cycle -Help plants grow – nitrogen fixing bacteria
5. GMO’S – are used to make insulin
6. Production of Vitamins – bacteria in the colon
7. Antibiotics - lantibiotics.
Over the past few decades, bacteria have evolved to resist our antibiotics. As a result, hospitals have seen a dramatic rise in drug-resistant infections, many of which are fatal.
To come up with new antibiotics, scientists often work with the natural chemical defenses of fungi and bacteria, altering these natural antibiotics to make new ones.

12. Bacteria that cause diseases in the human body
Staphylococcus
Streptococcus
Anthrax
E. Coli – beneficial inside the intestines

13. Eukaryotes Contain membrane-bound organelles
Multicellular organisms and some unicellular (amoeba, algae, and yeast)
Contain a nucleus
Control center of the cell
Contains a cell’s genetic material
Responsible for cell division
Manages all cellular functions
Identified by Rudolf Virchow
Examples: Protist, fungi, plants, and animals
Bigger in size than prokaryotes

14. Prokaryotes -vs- Eukaryotes
Smaller in size
Do not have membrane-bound organelles
Have genetic material (DNA) but not surrounded by a membrane
Circular DNA floats in cytoplasm
Unicellular organisms (bacteria)
****No nucleus or nuclear membrane***
have ribosomes, cytoplasm, and cell membrane
Contain membrane-bound organelles
Multicellular organisms and some unicellular (amoeba, algae, and yeast)
Contain a nucleus
Control center of the cell
Contains a cell’s genetic material
Responsible for cell division
Manages all cellular functions
Identified by Rudolf Virchow
Protists, fungi, plants, and animals
Bigger in size than prokaryotes

17. Card Sort Activity Each group will receive a set of cards.
Work in groups of 4 to sort terms that apply to prokaryotic and eukaryotic cells.
Have your work checked by the teacher once you have completed sorting the characteristics of prokaryotic and eukaryotic cells.
