Finding Nemo Themed Cell Organelles
Transcript of Finding Nemo Themed Cell Organelles
-intracellular digestion via enzymes within the lysosome
-fusion with food vacuole to digest food from outside that can be used for energy later (called phagocytosis)
-autophagy (recycling of damaged organelles in the cell using enzymes) Functions include
-production of lipids
-metabolism of carbohydrates
-detoxification of drugs and poisons
-making of steroids
-storage of calcium ions necessary when muscle cells are stimulated A network of membranes with ribosomes which
-makes membranes for within the cell by adding membrane proteins and phospholipids to its own membrane
-produces its own membrane phospholipids
-the ribosomes make secretory proteins
-transport vesicles move endoplasmic reticulum membrane to other parts of the endomembrane system Ribosomes Cell Organelles Central vacuole in plant cells -stores organic compounds and inorganic ions -acts as disposal place for harmful waste products -contains poisonous compounds to defend against predators -plays large role in cell growth (grows as it absorbs water) Food vacuoles -carry food molecules into cell and fuse with lysosomes for phagocytosis Contractile vacuoles -pump extra water out of cell to keep the correct concentration of molecules and ions Contractile vacuoles The vacuole is represented by the puffer fish named Bloat in Finding Nemo.
-He puffs up whenever he is frightened similar to how the central vacuole grows in size as it absorbs water.
-Also, his spikes help him defend predators like the vacuole can contain poisons to defend the plant. Jacques cleans off new fish when they enter the fish tank just as the lysosome breaks down food when it enters the cell. The whale represents the smooth endoplasmic reticulum because it has to get rid of Marlin and Dory when they are trapped inside of it. The smooth endoplasmic reticulum helps get rid of drugs and poisons that enter cells. Complexes made of ribosomal RNA that
-free ribosomes in the cytosol make proteins that function in the cytosol
-bound proteins attached to the endoplasmic reticulum or nuclear envelope make proteins that will be put into the membrane or that will be secreted from the cell Golgi Apparatus The golgi
-produces macromolecules such as pectins and polysaccharides that are not made of cellulose
-modifies, stores, and then sends products from the endoplasmic reticulum including proteins
-the cis face near the ER receives products carried in transport vesicles and the trans side ships modified materials
-before shipping products the Golgi sorts them and identifies where they will go Crush receives Marlin and Dory after they go through the jellyfish and helps them figure out where they should go next to get to Sydney.
The golgi apparatus receives products from the endoplasmic reticulum and sorts them out. The schooling moonfish in Nemo make various formations to help Marlin and Dory on their journey. The ribosomes make proteins which code for certain phenotypes in organisms. Nucleus -contains DNA organized in chromosomes which carry genetic information
-inside the nucleus is the nucleolus which is where the DNA gives instructions which will be used to make RNA
-basically the nucleus directs protein synthesis
-when RNA goes into the ribosomes, specific polypeptide chains are formed which make proteins Peroxisomes Oxidative organelles
-have enzymes which trasnfer hydrogen to oxygen making hydrogen peroxide-this reaction serves a purpose
-oxygen is used to break fatty acids into smaller molecules that are transported to the mitochondria where they are used for cellular respiration
-in the liver peroxisomes detoxify alcohol
-they also convert the harmful hydrogen peroxide that they create back to water Mitochondria Sites of cellular respiration
-extract energy from sugars and fats
-this energy is used to make ATP
-has a smooth outer membrane and folded inner membrane (the foldings are called cristae and they have a large surface area to maximize the production of ATP)
-the inner membrane divides the mitochondria into the innermembrane space and the mitochondrial matrix that has enzymes to help with cellular respiration Chloroplasts Site of photosynthesis
-converts energy from the sun which is captured by the chlorophyll into chemical energy
-the chemical energy can be used in the synthesis of organic compounds within the cell
-they have two main parts: the thylakoids and the stroma Bubbles the fish enjoys making oxygen bubbles by opening the treasure chest in the fish tank. The peroxisomes make hydrogen peroxide with hydrogen and oxygen, but also break down hydrogen peroxide into oxygen again. The anglerfish in Finding Nemo needs a light to see prey at the bottom of the dark ocean. The chloroplasts need the sun's light to be able to go through the process of photosynthesis. Gill devises a plan for Nemo to get back to his dad, Marlin. He is a smart fish. The nucleous contains genetic information which is like a plan for making RNA which will then make ribosomes. Squirt the baby turtle has seemingly endless energy just like the mitochondria supply endless energy to cells. Pearl, the pink octopus, makes ink to defend herself from predators. The rough endoplasmic reticulum makes its own membranes and the ribosomes on the rough ER make secretory proteins. Bibliography Campbell, Neil A., and Jane B. Reece. Biology.
