Transcript of Biology Project

Finally Aquariums relate to plant cells in many more ways than we expected! Cell Wall Plant Cell: An Aquarium This part of a plant cell protects and supports the cell, and materials cannot pass through most of it. Cell Membrane The cell membrane controls the entry of foreign substances into the cell, and is another form of protection. Cytoplasm The cytoplasm includes all contents of the cell except the nucleus. In a cell, this is mostly water. Nucleus The nucleus of a cell is the control center, contains the DNA, and contains the nucleolus. This is like the glass of an aquarium, because it protects the inside of the aquarium and holds it together. This is like a filter in an aquarium because it filters out foreign things, and makes sure the water stays clean and pure In an aquarium, this is like all the water inside the glass. It engulfs everything, and contains everything except the nucleus (fish castle). The nucleus is like the fish castle in the aquarium. It is in the center, contains the treasure chest (nucleolus), and is made up of bricks (chromosomes). Nucleolus The nucleolus is responsible for making ribosomes, and is inside the nucleus. The nucleolus is like the treasure chest within the fish castle. It makes bubbles (ribosomes), and is essential to the aquarium. Chromosomes Chromosomes are made up of DNA, determine the type of cell it is, and are found in the nucleus. The chromosomes are like the bricks of the fish castle because they build it up and determine the type of castle. Endoplasmic Reticulum The endoplasmic reticulum is a network of membranes throughout the cell, in charge of the synthesis of proteins. The ribosomes stick to the membrane and aid in the synthesis. This is like kelp in the aquarium. The kelp is making food (like protein) for the organisms in the aquarium. The bubbles (ribosomes) stick to the kelp. Ribosomes Ribosomes aid in the synthesis of proteins, and attach themselves to the Endoplasmic Reticulum in order to do so. This is like the bubbles in the aquarium. They are made by the treasure chest, and float over and attach themselves to the kelp. Mitochondria Powerhouse of the cell, packs the food energy into ATP, amount varies on type of cell This is like the fish in the aquarium, who eat their food, and then convert it to energy so they can swim around and power the aquarium. Vacuole The vacuole looks empty in plant cells, but contains water, sugar, ions, and other pigments This is like the water current in the aquarium. It's invisible, but it is important to aquarium life. Chloroplast The chloroplast is the part of the cell where photosynthesis takes place, and only in plant cells. This is like solar panels in our aquarium. They transfer light to energy, just like chloroplasts. Golgi Body/Apparatus The golgi body is responsible for sorting and correctly directing the proteins created by the endoplasmic reticulum. This would be like the hand that feeds the fish their food. He or she directs it into the aquarium. Microtubules Microtubules make up the cytoskeleton, and are responsible for transporting molecules. This is like shrimp in an aquarium, because they attach themselves on the cell wall and transport things back and forth around the aquarium.
