The 8 Levels of biological organization:1. Atom2. Molecule3. Organelle- cell parts4. Cell-basic unit of life5. Tissue-cells that work together6. Organ-tissues that work together7. Organ System-organs that work together8. Organism-living thing

1. Whose experiment was this?2. What did it prove?3. Which is the control?4. Which 2 are the experiments?5. What is a maggot?

Read the pages in the book that outline the cell organelles.Use your color pages and the information to complete the cell organelle chart.

Warm up

Cell WallRigid covering over cell membranePlant cellsKeeps cells shape and protectionCellulose

Cell membranesemi-permeableSOME things can go in and out2 layers of lipids (fats)

Nucleuscontains DNAdouble membrane for protectioncontrol center for the cell

CytoplasmFluid surrounding the nucleusContains all the organelles

Golgi apparatusstack of membranespackages things to transport themex: package hormones, etc

Endoplasmic reticulum:folded pathway of membranesrough: has ribosomesmake proteinsmooth: has no ribosomestransport

Ribosomes:grains on ER and floating in cytoplasmtransfer messagesmake proteins

Mitochondriabreak down sugar to release energypowerhouse of cellhas its own DNA!!!

Vacuolelarge sac that helps store and digestkeeps plant cells from "wilting"

Lysosomecommon in animal cellsholds enzymes for digestion

Chloroplastin plantschlorophyllconvert sunlight to sugars

Explain how the structure of the cell membrane controls what enters and leaves the cell.

How do you think new cells are "born"?

How do we look at cells if they are so small?
