7 Characteristics of Living Things

Cells KWL

Watch Video & Add to Chart (in any section) A A

The Cell* The basic structural and functional unit of all organisms Cells may exist as independent units of life Cells may form colonies or tissues  ex. plants or animals Journals out!!

Cell Theory* 1) All living things are made of cells 2) Cells are the basic units of structure & organization in living organisms 3) Cells arise from pre-existing cells How did we come up with this definition??

Story of Cell Theory U U

Video Recap* Where and when did cell theory begin? Netherlands in 1600 Who is Anton van Leeuwenhoek? Scientist who made his own microscope and discovered bacteria What was the first name given to bacteria? Animalcules Why did Robert hook call the little microscopic compartments “cells”? Looked like little monasteries to him How do we quickly write these as notes?

Scientific Discoveries Takeaway What does the video suggest about the nature of scientific discoveries? They don’t happen alone! It takes many people (providing MANY sources of evidence!!) to see a discovery come to life.

2000 Years of “Spontaneous Generation” What does it mean?? Even multiple pieces of evidence can lead to the wrong idea! That’s why you always keep searching. *Spontaneous Generation was the (incorrect) idea that non-living things could produce life Ex. Rotting meat  maggots

Cell Theory

Cell Types* ____________________ vs. _______________________ No nucleus No organelles with membranes Example: ____________________ Contain nucleus Contain membrane- enclosed organelles Examples: ____________________ Do you know??

Prokaryotic vs. Eukaryotic POGIL worksheet

Exit Slip How is cell structure related to function? Provide at least two examples in your answer.

Identify each cell as either prokaryotic or eukaryotic 10/7/15 Date:10/6/15Topic:Comparing/Contrasting CellsPage # ___

POGIL Review Fill in answers if you missed them!

Prokaryote vs. Eukaryote* Video Review: SMCmWB1s SMCmWB1s How is a small and simple structure useful for prokaryotic cells? Allows for quick reproduction!

Prokaryotes Eukaryotes

Organelles* All cells have what 3 structures in common? Cell membrane: separates inside of cell from environment Cytoplasm: “the gel inside the cell” DNA: passes on genetic material for reproduction

Organelles* What does organelle mean? Little organ Nucleus: “Control Center” of cell (holds DNA) Nuclear membrane: Thin layer that holds chromatin (uncoiled DNA)

Organelles* Nucleolus Makes ribosomes Ribosomes Make proteins Endoplasmic Reticulum Pathway that transports materials (ex. Proteins)

Organelles* Vesicles Capsules for transport Golgi apparatus Packages proteins Vacuole Storage chamber (large in plants, small in animals)

Organelles* Lysosome Cleanup crew (enzymes break down debris) Mitochondria Make energy (ATP) Cytoskeleton Protein tubules that keep cell structure

Organelles* Chloroplast Site of photosynthesis (green pigment = chlorophyll) Cell Wall Hard outer layer of plant cell (gives structure) Cilia Tiny hairs used for movement

Organelles* Flagella Tail-like structure used for movement Centrioles Bundled protein structures that help with cell division in animal cells
