Transcript of Plant Cell Parts

This is a plant cell. It has a lot of parts to it called organelles. As the name suggests, they are like body organs. Each has a specific purpose to help the cell thrive. Plant Cell Parts Lets start off with the most important, shall we? The nucleus is the main organelle. It controls everything that goes on in the cell. Here is a picture. The nucleus is like the human brain. Both control all parts of the body, or cell. This right here is called the nucleolus. The nucleolus produces ribosomes. The nucleolus is like a car factory. It produces cars that also produce something. These strands here are called chromatin. They are the "directions" of the cell, which tell everything about it, even when it is suposed to die! The chromatin are like video game directions, since each tell the elements and directions of the subject. The surface there is called the nuclear envelope. As its flexible structure suggests, its purpose is to protect the nucleus. It has many pores. The nuclear envelope is like the human skull; both protect the "brain", or main body part. The outside of the cell is called the cell wall. The cell wall's purpose is to support and protect the cell. The cell wall is like skin, because both protect the main body, or mass. The smaller section is called the cell membrane. The cell membrane lets nutrients in, but keeps poison and such out. These little dots are called ribosomes. The word 'rib' in the name tells a bit about it. It produces the protein that the cell needs. The ribosomes are like the cars. They produce CO2, but the ribosomes produce something better. This thing that looks like a maze has a long name. It's called the endoplasmic reticulum. Ribosomes The "ER" carries protein (ribosomes) from one place to another. The "ER" is like the subway. Each transports its "passengers" from one place to another. The cell membrane is like a poncho. They are both flexible, and both let good things in, but keep bad things out. Heat Ribosome :) This mass of flattened tubes is called a Golgi body, named after Camillo Golgi, who discovered them. The Golgi body "packages" nutrients and sends them to other parts of the cell. The Golgi body is like a post office. Both send materials to other areas. This thing that looks like a peanut shell is called the mitochondria. This is the cell's power source. This has a number of things it could compare to. It is like a power line, or a solar panel, because they all give and convert power to the object. This green dome is a chloroplast. The chloroplasts' job is to capture sun and use it to make food, a process called photosynthesis. This organelle is like a solar converter. It captures energy and uses it to power the cell, or truck. nutrients nutrients nutrients nutrients biofuel biofuel biofuel This big blue sack is called a vacuole. The vacuole acts as storage for the cell. The vacuole stores extra wastes and nutrients. wastes nutrients The vacuole is like a warehouse. Each stores essential materials. (pumps blood) CO2 This concludes my presentation. Thanks for watching! This is a Zombatar!
