3 Eukaryotic Cell Nucleus Nickname: “The Control Center” Function: holds the DNAParts:Nucleolus: dark spot in the middle of the nucleus that helps make ribosomes
4 Located Inside the Nucleus ChromatinFunction:Material in cells that contains DNA and carries genetic information and direct functions of a cell.Thin strands inside the nucleus.
5 When the cell get ready to divide it makes ChromosomesFunction: Carries genetic information that control inherited characteristics such as eye color and blood type.DNA is always in the form of chromosomes.

7 Eukaryotic Cell Organelles and Function RibosomesNickname: “Protein factories”Function: Produce proteinsProteins are passed to the interior of the endoplasmic reticulum. From there they will be transported to the Golgi bodies.Found in all cells, prokaryotic and eukaryotic
8 Eukaryotic Cell Organelles and Function Endoplasmic Reticulum (ER)Nickname: “Passageway”Function: Passageway that carries proteins and other materials from one part of the cell to another.

10 Endoplasmic Reticulum 2 Types:Rough ER:Rough appearance because it has ribosomesFunction: helps make proteins, that’s why it has ribosomesSmooth ER:NO ribosomesFunction: makes fats or lipids
12 Eukaryotic Cell Organelles and Function Golgi ComplexNickname: mailroomFunction: receives, packages, and distributes proteins and other materials to different locations inside/outside of the cellAppearance: stack of pancakes
13 Eukaryotic Cell Organelles and Function Lysosomes: circular, but bigger than ribosomes)Nickname: “Clean-up Crews”Function: to break down large food particles into smaller ones. Also, breaks down old cell parts and release substances to reuse.
14 Eukaryotic Cell Organelles and Function MitochondriaNickname: “The Powerhouse”Function: Produce most of the energy the cell needs to carry out its functions.Muscle cells have large numbers of mitochondria.Breaks down food to make ATPATP: is the major fuel for all cell activities that require energy
18 Eukaryotic Cell Organelles and Function 7. Cell MembraneNickname: “Gatekeeper”Function: forms outside boundary of animal cell and allows materials to move in and out of the cellSelectively permeable – allows some substances to move through and some cannot.
20 Now let’s talk about structures only found in PLANT Cells!!
