Do Now: List Four Things that you know about cells: 1 2 3 4 List one Wondering you have about cells. FOR EXAMPLE: I wonder weather there is only one type of cell or if there are more than that.

Agenda Big Skill: Communication Your Goal: Be able to communicate Do Now Agenda Notes Exit Slip Big Skill: Communication Your Goal: Be able to communicate the different types of cell Monday Tuesday Wednesday Thursday Friday PROKARYOTES VS. EURKARYOTES Stem Cells Discussion. Cell Membrane/Inquiry activity Semi-Permeable LAB QUIZ DAY NO NOTES

CHALLENGE Since we are working on communication… I am challenging my two biology classes to compete against each other. THE CLASS THAT HAS THE LEAST SWEAR WORDS SPOKEN OVER THE NEXT WEEK GETS DONUTS ON FRIDAY DURING THE QUIZ. WHY? What do you think?

The Why Junior class has had it rough… BUT we are out to prove them all wrong and make you’re the most successful yet. WE ARE IN IT TO WIN IT. In order to find success within the ‘SYSTEM’ … we need to have the skills that allow us to navigate it. One of those skills is STANDARD English.

Prokaryotes Vs. Eukaryotes Types of Cells Prokaryotes Vs. Eukaryotes

Two types of Cells: Eukaryotes and Prokaryotes

Prokaryotes are surrounded by a cell wall, plasma membrane and contain only DNA and Ribosomes. Example is bacteria.

Stop and Think: What do DNA and Ribosome's do in a cell Stop and Think: What do DNA and Ribosome's do in a cell. Get creative what do you think? 1 minute.

Eukaryotes –contain organelles; makes and transports proteins Organelles are small specialized, membrane-bound structures inside a cell

TURN AND TALK EXPLAIN TO THE PERSON SITTING NEXT TO WHAT THE DIFFERENCES AND SIMILARITIES ARE BETWEEN PROKARYOTES AND EUKARYOTES ARE BE READY TO SHARE OUT WITH THE CLASS

Cell size comparison most bacteria eukaryotic cells Animal cell Bacterial cell Animal cell most bacteria 1-10 microns eukaryotic cells 10-100 microns micron = micrometer = 1/1,000,000 meter diameter of human hair = ~20 microns

Eukaryotic cells Multicellular - organisms made of more than one cell, such as plants and animals Unicellular - made of one cell) Examples are amoebas, algae and yeast.

Organelles - Structure Many different organelles in eukaryotic cells. Each has different structure and function.

The Jobs of Cells Cells have 3 main jobs Generate energy Make proteins need energy for all activities need to clean up waste produced while making energy Make proteins proteins do all the work in a cell, so we need lots of them Make more cells for growth to replace damaged or diseased cells Our organelles do all these jobs!

Important Organelles Membrane: surrounds the outside of the cell, made of the same things as the outside of many organelles inside the cell. Nucleus Contains all of the DNA in the cell Considered the ‘brain’ of the cell

Stop THINK, PAIR and SHARE WHY IS THIS USEFUL?

Important Organelles Mitochondria Energy generating organelle In both animal and plant cells Chloroplast Energy gathering organelle Only in plant cells

Structure – Animal Cell

Structure – Plant Cell

Exit Slip What are 2 differences and similarities between prokaryotes and eukaryotes? Which cells are bigger? Prokaryotes or Eukaryotes?
