This is a school project made by Collin Barlage and Donald Pierce. We made this with 3D S max and After Effects TRANSCRIPT: Plant cells are eukaryotic cells that differ in several key respects from the cells of other eukaryotic organisms. One of their distinct features is their Cell Wall. The Cell Wall is a lipid bilayer that forms the outer boundry of the cell. A main function of the cell wall is to act as a pressure vessel, preventing over-expansion when water enters the cell. Although the material of the cell wall varies dependant upon species, it serves the same purpose. As we move further into the cell you'll notice very important differences between an animal cell and this plant cell. Starting just under the cell wall there is an additional wall-like structor called the cell, or plasma, membrane. The Cell membrane is selectively permeable to ions and organic molecules protecting the cell from outside forces. The Cell membrane has complete control over the movement and substances in and out of cell. Underneath the cell membrane is a thick layer of cytoplasm. The Cytoplasm is a gel-like substance that holds all of the cell's substructors and organelles. It is within the cytoplasm that most cellular activities occur, such as many metabolic pathways and cell division. In the cytoplasm the organelle that takes up most of the cell's space, is the Vacuole. The vacuole is an enclosed vesselle that contains mostly water and enzymes. The Vacuole is in charge of maintaining pressure and turgor within the cell. The Vacuole also helps maintain an acidic internal pH level Since plant's and algeas do not obtain energy from other organisms, an organelle supplies energy to the cell by converting energy from the sun into usable energy by the cell with a process called Photosythesis. The organelle is called the Chloroplast and is located within the cytoplasm of the cell. -zoom- -pause- The apparatus that is in charge of packaging and sending proteins is located just away from the endoplasmic reticulum. The Golgi Complex -zoom- is particularly important in the PROCESSING of proteins for secretion. The Mitochondrian are sometimes described as the power plants of the cell because they generate most fo the cell's supply of adenosine triphosphate, used as a source of chemical energy.The Mitochondrian lie in the cytoplasm just away from the Golgi Apparatus. The endoplasmic Reticulum are eukrayotic organelles that form an interconnected network of tubules and vesicles. The endoplasmic Reticulum curves itself around the nucleus and comes in two forms, rough and smoth. The organelles may seem similar but are truely very diferent. -pan/zoom- The rough edoplasmic reticulum is studded with ribosomes giving it a "rough" appearence. Where as the smooth endoplasmic reticulum has several functions. This reticulum not only synthesises lipids and steroids, but is attached to the nuclear envelope. This allows the transfer of ribosomes. -zoom as ribosomes move- Ribosomes are a component of cells that assembles the twenty specific amino acid molecules to form the particular protein molecule determined by the nucleotide sequence of an RNA molecule. The Nucleolus produces ribosomes and realeases them to the rough endoplasmic reticulum. As depicted, there are a significant about of ribosomes attached to the Rough Endoplasmic Reticulum. Lysosomes are another holder of enzymes in the cell. Located within the cytoplasm, the Lysosomes break down waiste and other cellular debris. The Nuclulous is surrounded by a nuclear envelope, and is the control centre of the cell.
