WARM UP TASK 11/27 Read each statement on your “Intro to Cells video sheet” and put a T or F on the LEFT SIDE ONLY. (you are making your best guess)

AGENDA 11/27 1.Ch 4 Notes #1 Intro to cells 2.Intro to cells video 3.Do you know your own cells? * Can get EC from this! * Can get EC from this! *** MISSING TESTS – TAKE TOMORROW!!!!

LEARNING TARGET CHAPTER 4 #1 I can explain the major events in cell history.

Ch 4 NOTES #1 11/27 THE CELL intro

3.6 billion years ago – 1 st cells PROKARYOTE - bacteria No nucleus

outube.com/ watch?v=Ra AM8qQcs6E &sns=em

1.3 billion years ago EUKARYOTE CELLS – do have nucleus ; also organelles

Over time …. Cells became specialized – different cells do different things Brain cell Blood cell Skin cell…. and grouped together to become multicellular.

TAKE YOUR INTRO TO CELLS VIDEO SHEET OUT CELL VIDEO – while watching, write down if the statement is T or F. See how many you got right!

1668 VanLeeuwenhoek Developed the 1 st microscope

1670’s HOOKE 1 st saw cells (cork) AND named CELLS Cellula = small compartment

1838 SCHLEIDEN AND SCHWANN All living things are made of cells

1858 VIRCHOW All cells come from cells

REVIEW….. 1.What came first, eukaryote or prokaryote? 2.EXPLAIN how one evolved into the other. 3.Name 4 people who contributed in the history of cells. * What did they do?

CELL THEORY 1.All living things made of cells. 2.Cells are the basic unit of all living things. 3.All cells come from pre- existing cells (exception: first cell ?????)

CYTOLOGY The study of cells CELLS – the basic unit of all living things

About 75 trillion in the human body! Around 200 different types Many different shapes, sizes and functions

Smallest cell: 1/12,000 inch blood cell Largest cell: 1/300 inch female egg Longest cell: around 3 feet nerve cells

ORGANELLE CHART Using the sheet of organelles and what they do, fill in your chart ASSIGNMENT

Before 1660’s – SPONTANEOUS GENERATION THEORY SPONTANEOUS GENERATION THEORY “living things come from non- living things” Kill a young bull, and bury it in an upright position so that its horns protrude from the ground. After a month, a swarm of bees will fly out of the corpse. Place a dirty shirt or some rags in an open pot or barrel containing a few grains of wheat or some wheat bran, and in 21 days, mice will appear.
