Cell Structure & Function http://koning.ecsu.ctstateu.edu/cell/cell.html

Cell Theory 1.)All living things are made up of cells. 2.)Cells are the smallest working units of all living things. 3.)All cells come from preexisting cells.

Prokaryotes v.s. Eukaryotes Two Cell Categories Prokaryotes v.s. Eukaryotes Pro=NO Eu (you)=Do No nucleus Nucleus No organelles Many organelles Only Bacteria All Other Cells Bacteria Plant Animal

The smallest unit capable of performing life functions. Cell The smallest unit capable of performing life functions.

Examples of Cells Amoeba Proteus Plant Stem Bacteria Red Blood Cell Nerve Cell

Cell Parts Organelles- Specialized structures in eukaryotic cells that perform specific functions.

Surrounding the Cell

Cell Membrane A semi-permeable membrane controls what enters/exits the cell. (plants AND animals) http://library.thinkquest.org/12413/structures.html

Cell Wall The cell wall gives the plant cell structure and support http://library.thinkquest.org/12413/structures.html

Inside the Cell

Nucleus The nucleus is the brain of the cell. Controls cell activities and protects the DNA

Chromosomes Chromosomes (made of DNA in the nucleus) have instructions for your traits http://library.thinkquest.org/12413/structures.html

Cytoplasm Gel-like mixture called cytoplasm is surrounded by the cell membrane.

Endoplasmic Reticulum The Rough Endoplasmic Reticulum moves materials around in cell (has ribosomes attached) http://library.thinkquest.org/12413/structures.html

Inside the cell The Smooth Endoplasmic Reticulum helps makes lipids

Inside the Cell Mitochondria breaks down food/oxygen to create energy/power in the form of carbohydrates for the cell http://library.thinkquest.org/12413/structures.html

Inside the Cell Proteins are made by the ribosomes http://library.thinkquest.org/12413/structures.html

Golgi Bodies Protein are modified, packaged, sorted and shipped by the Golgi Bodies. http://library.thinkquest.org/12413/structures.html

Inside the Cell Photosynthesis (conversion of water, sunlight, and carbon dioxide into carbs) happens in the chloroplast of only plant cells http://library.thinkquest.org/12413/structures.html

Vacuoles Vacuoles are storage sacs wastes and water. http://library.thinkquest.org/12413/structures.html

Lysosome Lysosomes comes from Golgi Body They breaks down/digest: proteins, nucleic acids, carbohydrates, phospholipids Breaks down cells when it’s time for them to die Removes waste from cells http://library.thinkquest.org/12413/structures.html
