slide1

HELLO! When you arrive to class today…1. Please get out your Agar Lab.2. Complete the “Post-Lab” Questions with the person sitting next to you.3. Have your notes from last night’s homework video on your desk!

slide2

Bellwork: September 4Look at the two cells below (A and B). Write at least 5 things you observe about these cells. (Example…tell me how they are similar or how they are different)

Cell A

Cell B

slide3
Science Fact of the Day:The Golden "Poison Dart" frog in South America is most poisonous vertebrate in the world.
slide4

CO:I will compare and contrast types of cells.LO:I will complete a T-Chart to compare/contrast prokaryotic and eukaryotic cells. I will look at types of cells with a partner.

how to fill in your notes
How to fill in your notes:

Prokaryotes

Eukaryotes

BOTH

six characteristics that all cells have in common
Surrounded by a cell membrane.

Have ribosomes (make proteins)

Contain DNA

Have the ability to reproduce

Maintain homeostasis

Respond to stimuli

Six characteristics that all cells have in common:

Write this in the “BOTH” column!

slide9
EukaryotesThe next few slides will go on the right side of your T-Chart under “Eukaryotes”ONLY write the information in BOLD!
eukaryotes can reproduce sexually or asexually
Eukaryotes can…reproduce sexually or asexually
  • Asexual reproduction of a sea anemone by fission.
slide16
ProkaryotesThe next few slides will go on the left side of your T-Chart under “Prokaryotes”ONLY write the information in BOLD!
prokaryotic examples bacteria
Prokaryotic examples: bacteria.

WHEN I SAY PROKARYOTE,

YOU SAY BACTERIA!

flip your notes over on the top of the paper write endosymbiotic theory only write what is in bold
Flip your notes over……on the top of the paper write “Endosymbiotic Theory”Only write what is in bold!
endosymbiotic theory
Endosymbiotic Theory
  • “endo” = inside of
  • “sym” = together
  • “biotic” = living
  • “theory” = scientific explanation based on scientific evidence

…Put that all together and you get…

endosymbiotic theory1
Endosymbiotic Theory
  • The theory that the eukaryotic cell is actually composed of prokaryotic cells
    • One prokaryotic cell living inside of another prokaryotic cell, made a more complex cell called the eukaryotic cell
  • Organelles were once independent prokaryotes

slide28

Below your notes, number 1-6.With a partner, decide whether the cells on each slide are a prokaryotic or eukaryotic slide.Be sure to put a reason WHY you chose your answer. The team to get the most right will get a prize 

answers
Answers:
  • Prokaryotic—no nucleus, no organelles
  • Eukaryotic—plant cells, green discs are chloroplasts (organelle)
  • Eukaryotic—complex, contains a nucleus, many organelles
  • Prokaryotic—small, simple, no organelles are seen
  • Prokaryotic—small, simple, no organelles are seen
  • Eukaryotic—unicellular, organelles present

Exit Ticket!
  • On your stickie note write 3 major differences between prokaryotic and eukaryotic cells.
  • You do not need to put your name on it!
