Transcript of Cell Analogies Collage

Parts of a Cell
A cell has many parts that all have their own function and job. These structures are what keep the cell going and help it to maintain homeostasis, preventing them lysing and being destroyed. Parts of a Cell mitochondrion Cell Analogies Collage Centrioles ribosomes endoplasmic reticulum Cell Membrane cilia nuclear envelope cytoplasm nucleolus chromatin golgi apparatus nucleus lysosome ANIMAL CELL This is an ... Other structures found in plant/bacteria cells: (cc) image by nuonsolarteam on Flickr cytoskeleton: made up of microtubules and micro/interemediate filaments Function: gives the cell support/helps maintain shape Analogy... This is similar to the skeleton(bones) on a human because they help us maintain our shape and give us the support we need to move. is like a separated trash/recycle bin because it organizes all of the waste into different categories(trash, paper, plastic) just like the centriole organizes microtubules. Function: organizes cilia, flagella, and other microtubules in the cell Function: digestion of fats and lipids(get rid of wornout organelles and waste produced by the cell) Analogy: Lysosomes are like incinerators because they rid the cell of waste and trash, getting rid of it rather than allowing it to pile up(like a garbage can/dump) Function: protein synthesis Ribosomes are like a chef, making the protein that the cell needs to survive and essentially feeding the cell Function: the production of various materials, composed of a ROUGH and SMOOTH part
Rough: has ribosomes attached and is involved mainly in protein synthesis
Smooth: does not have ribosomes, and produces lipids and hormones The E.R. is like a factory, producing things that are needed around the cell. It works, therefore, hand in hand with the Golgi apparatus(the post office) to ship the materials it produces all over the cell. Function: regulates what goes in and out of the cell The cell membrane is like a gate or a locked door because it only allows certain things in or out, and they must have the right code/key in order to do so. Function: used for movement Cilia are like little ants, moving large pieces of material across a cell. they help to not only move the cell, but to move things within the cell, "surfing" or "floating" them from place to place, much like an army of ants. Function: surrounds and protects the nucleus, regulating what information goes in and out The nuclear envelope is much like an army, because it surrounds the most important part of the cell, protecting it from harm and allowing only important information to pass through. Function: holds information about genes and DNA needed for cell reproduction Chromatin is like a library, because it holds information about cell reproduction, just like books hold information, and it stores it in case the nucleus needs it. Function: Makes copies of DNA and produces ribosomes(used for protein synthesis) The nucleolus is like a copy machine because it makes copies of the DNA to distribute throughout the cell. Function: control center of the cell(growth and reproduction) The nucleus is like the brain of the cell because it controls everything that goes on, sending messages throughout the cell, much like the brain regulates our whole body, using nerves and receptors to maintain homestasis. Function: modifies and packages proteins to send around the cell The Golgi Apparatus is like a Post Office because it packages all of the proteins and other products needed around the cell and sends them off. Function: holds all of the organelles in a cell The cytoplasm is a lot like a swimming pool, containing all of the organelles floating in it like pool floaties. Function: powerhouse of the cell; generates energy and is the location of cellular respiraton/aerobic exercise The mitochondria is like a battery or a generator, providing energy for the cell. This is a PLANT CELL.... And this is a bacterial flagellum cell... Vacuoles store water, waste, and food in a cell. They are more prominent in plant cells, although small ones exist in animal cells. Vacuoles are like closets, because they store things for the cell until it needs them, much like we store coats/out-of-date clothing in closets. Cell Wall: protects the outside of the plant cell, regulating what goes in and out The cell wall is like our skin because it protects the inside of the cell, like skin protects our inner body, and it has multiple layers to create thickness, just like the skin. Function: the flagellum assists the cell in motion The flagellum is like the motor on a boat, located at the rear end and propelling the cell forward. Chloroplasts: photosynthesis and give the plants their green color The chloroplast is similar to a solar panel system because it converts solar energy into chemical energy, like we convert it into electrical energy.
