I. Parts of a Eukaryotic Cell A. The Cell Membrane (Plasma Membrane)* Made of a bilayer of fat (phospholipids) with embedded proteins throughout Separates the inside and outside of the cell www.youtube.com/watch?v=LKN5sq5dtW4

Controls the transport of materials into and out of the cell Recognizes and responds to signals from other cells www.youtube.com/watch?v=GW0lqf4Fqpg

B. The Nucleus Controls and coordinates the activities of the cell Stores the cell’s DNA DNA carries the instructions for making proteins

During cell division, chromatin condenses into packages called chromosomes www.youtube.com/watch?v=ZK6YP1Smbxk

C. The Cytoplasm* The region between the nucleus and the cell membrane Filled with a jelly-like substance where many of the cell’s chemical reactions take place

D. Ribosomes* Tiny structures that synthesize protein Following the instructions in DNA Float in cytoplasm or found attached to the Rough Endoplasmic Reticulum (RER)

E. Mitochondria Site of cellular respiration Contains its own DNA G. Chloroplast – Plant Cells Only Site of photosynthesis Contains its own DNA

F. Vacuoles Storage sacs within the cytoplasm Contain either waste, water, or nutrients Plant cells have large central vacuoles

Some organisms have contractile vacuoles that pump excess water out of the cell

H. Cell Wall – Plant Cells Only Provides extra support for plant cells Made of cellulose

H. Other Organelles Endoplasmic Reticulum: passageway through cell Rough ER: covered in ribosomes; modifies proteins Smooth ER: synthesizes lipids

Golgi Body: packages and sends materials from the ER out of the cell

Cytoskeleton: gives the cell its shape and helps it move Cilia: small hairs on surface of cell Flagella: long tail on surface of cell

Lysosome – Animal Cells Only: digests substances in the cell Example: old organelles that need to be recycled

Centrioles – Animal Cells Only: helps the cell divide Cell Parts Video: www.youtube.com/watch?v=URUJD5NEXC8 Cell Rap: www.youtube.com/watch?v=-zafJKbMPA8 Another Cell Song: www.youtube.com/watch?v=rABKB5aS2Zg
