=__** ﻿ Eukaryotic Cells: The Inside Story **__=
 * __ Summary __**

Cell have many different organelle that heps it function. There is a cell wall that supports the cell membrane, a endoplasmatic reticulum that creates lipid. Cholorplast gives plant color and energy. mitochondria gives a cell protein while a golgi complex ships content around the cell. Vesicles form when cell membrane covers something outside and a vacuole that stores water for a plant. Finally lysosomes that eat used up things and dissolve cells.

__** Holding It All Together **__


 * All cells have an outer covering that seperates the inside of the cell from the outside
 * All the cells are covered with a cell membrane
 * The job of the cell membrane is to keep all the cytoplasm, allow nutrients in and waste out, and to interact with things outside the cell
 * The cell wall is only found in the cells of plant and algae
 * The cell wall is a layer that surrounds and provide strength and support to the cell membrane
 * The cell wall keeps the cell membrane from ripping when too much water enters the cell
 * Cell walls in plants are made of cellulose fiberthat crosses over each other
 * The strength of a cell wall can defy gravity

__** The Cell's Library **__


 * The largest and most visible organelle is the nuclues
 * Nucleus is the control center and contains DNA
 * The dark spot in the nucleus is the nucleolus
 * The nucleolus stores materials that will be used later to make ribosomes in the cytoplasm

__** Protein Factories **__

__﻿__ __** ﻿The Cell's Delivery System **__
 * Proteins are the building blocks of all cells
 * Proteins are made of amino acids
 * Amino cells are hooked together to make proteins at an organelle called ribosomes
 * Ribosomes are the smallest organelle
 * Ribosomes are the only organelles that have no membrane
 * Every cell needs ribosomes to live
 * The endoplasmic reticulum, or ER, is a membrane covered compartment that makes lipids and other materials to be used inside and outside the cell
 * The ER breaks down drugs and other harmful materials in the cell
 * The internal delivery system of a cell
 * The ER gathers the protein from the ribosomes and release it for use elsewhere

__** The Cell's Power Plants **__


 * Cells need energy to function
 * Food molecules are burned to release energy
 * The burned/broken down molecules are transfered a special moelcule called ATP
 * Mitochondria produce ATP
 * Mitochondria need oxygen to make ATP, and that is the reason we need to breathe
 * Plant and algae have an organelle called chloroplast
 * Chloroplast looks like stack of coins and contains a chemical called chlorophyll
 * Chlorophyll makes the plant green and traps sunlight to create sugar, this is the process of photosynthesis
 * The sugar is used by the mitochondria to make ATP
 * The mitochondria and the chloroplast are as small as a bacteria and have two cell membranes
 * They divide like a bacteria and known to be originated from prokaryotic cells


 * __ The Cell's Packaging Center __**
 * The golgi complex is the organelle that ships and processes proteins and other materials out of the eukaryotic cells
 * Named after the Italian scientist, Camillo Golgi
 * Golgi complex looks like a ER, but closer to the cell membrane
 * Lipids and proteins from the ER is delievered to the golgi complex to be modified for different function
 * The final product is enclosed in a piece of the golgi complex's membrane that pinches off to form a compartment where materials are put in to be shipped

__** The Cell's Storage Center **__
 * All eukaryotic cells have membrane covered compartmeent called vesicles
 * Vesicles cover objects outside the cell
 * Vacuole is a large membrane covered chamber that contains the plant's water
 * Vacuoles can change the color of a plant and contain the juice of a plant
 * Some unicelluar organisms that live in water has a special vacuole called contractile vacuole that squeeze out water when there is too much**__﻿﻿__**

__** ﻿Packages of Destruction **__
 * __** ﻿ **__ Lysosomes are special vesicles that contain enzymes
 * Lysosomes pour enzymes on a particle that is enclosed in a vesicle
 * Lysosomes destroy worn out or damaged cells
 * They protect the cell from waste materials and foreign invaders
 * Sometimes the lysosome break and spill the enzymes that destroies the cell
