Transcript of Computer Cell Metaphor

BY: DANIEL VAKARAU The cell membrane or the plasma membrane is a biological membrane that separates the interior of all cells from the outside environment.
Therefore the plasma membrane is like the firewall which is used to help keep a computer system secure and safe. Plasma Membrane Firewall Nucleus The nucleus is a membrane enclosed organelle found in eukaryote cells. It contains most of the cells genetic material, organized as multiple long linear DNA molecules in complex with a large variety of protein to make chromosomes.
Therefore the nucleus is like the motherboard which holds the CPU, memory, and other important material and carries out commands to make these things function. Nucleus Motherboard Lysosome The lysosome is an organelle that contains a large range of digestive enzymes used primarily for digestion and removal of excess or worn-out organelles, food particles, and engulfed viruses or bacteria.
Therefore the lysosome is like the recycle bin in a computer which stores unwanted icons before they are permanently deleted from a desktop. Lysosome Recycle Bin Ribosomes The ribosome provides one the things that cells need to survive; protein. They are the protein builders of the cell world, and are useful to the process of protein synthesis. Protein synthesis is the process of making protein with the help of RNA (ribonucleic acid) and will be stored for later use.
The ribosome is similar to the cache which stores data and will be ready for later use in the computer system like a ribosome does to protein. Endoplasmic Reticulum The endoplasmic reticulum (ER) is a network of flattened sacs and branching tubules that extends throughout the cytoplasm in plant and animal cells. The endoplasmic reticulum (both smooth and rough) manufacturers, processes, and transports a wide range of biochemical compounds for use inside and outside the cell.
Therefore the endoplasmic reticulum is like the circuitry in a computer system which transports as it carries materials throughout the system. Endoplasmic Reticulum Circuitry Golgi Apparatus The Golgi apparatus is found in both plant and animal cells, and is comprised of eight cup-shaped membrane covered sacs called cisternae. It packages proteins inside the cell before they are sent off to their destination; it is especially important in the process of secretion which releases, extracts, and oozes chemicals out of the cell.
Therefore the Golgi apparatus is like the computer router in a computer system as it packages and sends information back and forth between two computer networks. Golgi Apparatus Computer Router Mitochondria The mitochondria is the "powerhouse" of the cell. It is a rod-shaped organelle found within the cytoplasm of both plant and animal cells, and generates most of the cell's supply of adenosine phosphate (ATP) throughout the process of cellular respiration which is a series of metabolic processes that takes place within a cell in which energy is harvested from glucose and stored as energy carriers for use in energy- requiring activities.
The mitochondria is like the battery in a computers the battery breaks down molecules to release energy, which powers up the computer Mitochondria Battery Chloroplast Chloroplasts are the food producers of a cell. They are usually found in plant cells rather than in animal cells, and are crucial to the process of photosynthesis. The color green you see in plants are one of the pigments of the chloroplast which contains chlorophyll. The function of the pigments are also to absorb light energy, which is converted to chemical energy during the process of photosynthesis.
The chloroplast in a cell is like the power adapter in a computer, which converts AC power into DC power providing power for the computer. Chloroplasts Power Adapter Vacuole The vacuole is a membrane covered organelle that appears in both plant and animal cells. Vacuoles store food and nutrients that a cell needs to survive, and even store waste, so the rest of the cell is protected from contamination.
The vacuole is like the hard drive on a computer system which holds and receives folders that might be of use in a later time. Vacuole Hard Drive Ribosome Cache OVERVIEW Cell Structure Plasma Membrane

Description of the cell structure -Contains DNA, the blueprints for making necessary proteins -Organelles that contain digestive enzymes -Flattened system of tubular membranes

-Contains a highly folded inner membrane, an outer membrane and matrix.
-Contains a plant cell's thylakoids, stroma and grana, and chlorophyll.
-Phospholipid bilayer that surrounds the cell -Series of highly folded membranes suspended in the cytoplasm. Attached to it's outside are ribosomes -Series of highly folded membranes suspended in the cytoplasm. Nothing attached to it's outside.

-Round, non membrane bound organelle, found in prokaryotes and eukaryotes - Membrane-bound spaces; sacs surrounded by a membrane Organelle Functions -Controls all of the cell functions

-Digest excess or worn out organelles

-Makes proteins according to the instructions given by DNA
-Traps energy from sunlight in leaves; site of photosynthesis -Selects which molecules enter the cell -Produces and stores lipids -Sorts and packages proteins for transport out of the cell -Site of cellular respiration-to convert glucose into usable energy -Stores food, water, and sometimes waste materials -Sorts and packages proteins fro transport out of the cell
