Transcript of Biology Cell Analogy- House

Cell Analogy By Megan Charland The nucleus contains all of the DNA of a cell. It has coded intructions for making protein and other molecules. The nucleus contains the nuclear envelope chromatin, chromosomes, and the nucleolus. Your parents are like the nucleus. They control everything in the house... EVERYTHING..... The mitochondrion converts chemical energy stored in food into compounds that are more convenient for cellulose. A generator is like the mitochondrion. It take energy and distributes it through-out the house. The vacuole is a sac-like structure. It stores materials like water, salts, protein, and carbohydrates. In a plant cell, there is one large centeral vacuole cell. The pressure of the vacuole makes it possible to support leaves and flowers. A Storage room is like the vacoule. It can hold things until you need them. The cell membrane regulates what enters and leaves the cell by using the protein channels. In inside of the membrane is hydrophobic while the outside is hydrophilic. The doors in a house is like the cell membrane. It can only let things through when it is open. You can't go under a door, through a door, or over a door. The golgi apparatus modify, sort, and package protein and other materials from the ER for storage in a cell. A washer and dryer is like the golgi apparatus. the dirty clothes are the beginning product. The end product is clean clothes afterward. Ribosomes make proteins. The small particles of the RNA and protein found throughout the cytoplasm. Cells that are active in protein synthesis are often packed with ribosomes. The laundry basket is like a ribosomes. It helps transport dirty clothes to the washer. The endoplasmic reticulum (ER) are where lipid componants of the cell membrane are assembled, along with protein and other materials. It has an iternal membrane system. The Rough ER have a ribosomes surface. The smooth ER do not have any ribosomes on the surface. Making cookies is like the ER. When you make cookies, then you give them to someone else. The chroloplast uses photosynthesis. It also have 2 membranes. The inside membrane have large stacks of other membranes, when includes green pigment chlorophyll. Solar panels are like the chloroplast. The take solar energy and turns it into usable energy. The cell wall is outside of the cell membrane. It is the structure of the cell. The cell wall is like a wall in a house. Walls give support and structure to a house. The cytoplasm is in the cell. It is not the nucleus, but everything else in between. The cytoplasm is like air. It fills up the empty space in between everything else.
