Cell Analogy - The Soccer Field
Transcript of Cell Analogy - The Soccer Field
and the game it's played on Cell Wall - Goal Line Like the goal line on a soccer field, a cell wall acts
as a boundary in which EVERYTHING is kept and
keeps the shape of the cell, or in this case, the whole field. Cell Membrane - Sidelines The cell membrane is the outer layer of a cell that regulates what comes in and out of it, like the sidelines of the field regulate if the soccer ball is in or out Nucleus - Center Circle The nucleus of a cell is it's core, which
regulates the activity of the cell and contains
much of the cell's DNA, like the center circle
on the soccer field regulates how the entire
game goes after the initial kickoff. Nuclear Membrane - Boundary
of the Center Circle The Nuclear Membrane of a cell is the shell of the nucleus that surrounds it from the cytoplasm. Acts like a gatekeeper, allowing needed materials in the cell, and non-needed materials out of the cell. Nucleolus The nucleolus is the core of a cell nucleus that produces ribosomes (organelles made of protein and Ribonucleic Acid that are responsible for assembling the proteins of the cell). Like a center point being the core of a soccer field, the nucleolus marks the very core of a cell. Chromatin Chromatin, located in the nucleus, is composed of 50% DNA and 50% protein. Chromatin is what produces chromosomes and reproduces cells just like a soccer coach produces players for the game and reproduces other players whom may become injured. Cytoplasm Cytoplasm is the jelly-like, viscous cell substance where
all of the cell's organelles are held by a thick membrane. It's what holds everything in place like the grass of the
soccer field. Mitochondria An organelle in the cytoplasm of a cell which functions in energy production, like an energy drink or a protein shake does to a player before and/or after a game. Vacuole A vacuole is a membrane-bound basin in organic tissue which removes unwanted debris that surrounds the cell. Vacuoles in a cell are like the team mom in soccer, making sure everyone is clean and in top shape. Ribosomes Produced by the nucleus, ribosomes move out of the nucleus and position themselves where they are vital towards protein combination. They act like the spectators in soccer whom position themselves for the best view of the game. Endoplasmic Reticulum The Endoplasmic Reticulum is a system of tube-like membranes with smooth surfaces if not covered by ribosomes. This is where proteins are folded and where the transport of combined proteins occur. Only well folded proteins are taken from the ER to the Golgi Body. When players are passing the ball around in soccer, it relates to how the ER works, passing proteins to another thing for it to process with. Golgi Body The Golgi Body is an organelle that processes synthestics and secretions from the Endoplasmic Reticulum, where they are then released into the cytoplasm. They are like the defensive players on a team, whom kick the ball away from the goal like the golgi bodies package and distribute the synthetics and secretions.
Lysosomes Lysosomes are organelles containing enzymes that digest particles and disintegrate them after a cell's death. Again like a soccer coach, he/she replaces exhausted players for ones who are not, like the lysosomes replace worn-out cells. Chloroplasts Chloroplasts are small, double membrane organelles of only plant cells containing chlorophyll. They are the food producers of the cell. They are like the concession stand nearby in a soccer game (if there is one), providing drinks and snacks to the crowd. Chromosomes Chromosomes are any of several thread-like bodies that carry the genes in a continuous order - humans have 23 pairs, Chromosomes are produced by the chromatin. They are like the coaches: they contain the information of the Soccer game, and they direct the players on what they should do. Cytoskeleton The cytoskeleton is a moving lattice arrangement of structural components given throughout the cytoplasm, containing micotubules, microfilaments and larger filaments. The cytoskelton gives support to the cell structure and looks like the line that cuts a soccer field in half. Plastid Plastids, like chloroplasts, are small, double-membrane organelles also found only in plant cells. In a plant cell, they store specific things and form colorless bodies called proplastids, which, once formed, can convert certain kinds of plastids into other types. However, on the unfortunate side, there is nothing of a plastid that is related to soccer. Coming back to the sidelines on the soccer field, we could say that cilia and flagella in a cell would somewhat be like a cell membrane, except they allow function and movement to certain things, like the sidelines do for anyone within its boundaries. Cilia Identical to flagella, ciliae are hair-like organelles that provide travel to liquids along internal tissue within animals. Flagella Flagellum are hair-like organelles that allow movement of protozoa, sperm cells, etc. http://www.northland.cc.mn.us/biology/biology1111/animations/flagellum.html Centriole A centriole is a small, cylindrical organelle seen near the nucleus in the cytoplasm of most cells that divides in an upright fashion during a process called "mitosis". "Mitosis is nuclear division plus cytokinesis, and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase. Interphase is often included in discussions of mitosis, but interphase is technically not part of mitosis..." http://www.biology.arizona.edu/cell_bio/tutorials/cell_cycle/cells3.html http://www.cellsalive.com/mitosis.htm THE END Created by:
