FC: Wonderful Book of Cells
1: What's a cell? | A cell is functional basic unit of life. It is the building block of all living organisms. Everything has cells. Even bacteria, they are what scientist call unicellular, which means "single celled". Humans however or made up of about 100 trillion cells. Most cells are very small, microscopic, but some are large enough for the human eye to see. Here are the parts that make up a cell-
2: Cell Membrane | This is what a cell membrane is connected too. You guessed it, a plastic bag filled with holes. | This is ONE of the ways a cell membrane could look under a microscope. | The cell membranes main purpose is to help things get in and out of the cell. | The cell membrane is circling the rim of the cell. | The cell membrane is found in ALL cells. | The cell membrane is made up of two layers, these are called the phospholipids. The cell membrane is about 5nm thick. The cell membrane interacts with the other parts of the cell by keeping it clean and bacteria free.
3: Cell Wall | The cell wall, unlike the cell membrane is only found in plant cells. | This is a computer generation of a cell wall. | A cell wall is almost like the rim of a bowl, it helps balance the layers of the ''bowl''. | The cell wall most functions with the cell membrane. It keeps the structure of the cell while helping the cell membrane bring things in and out of the cell.
4: Cytoplasm | This is an example of microscope views on cytoplasm. | Cytoplasm's main function is to keep all of the organelles in place. This is also how it works with them, by keeping there work together. | Cytoplasm is almost like jello. If you've ever eaten jello with oranges in it, you know what I'm talking about. No matter how much it jiggles the oranges always stay in place. | The cytoplasm is located in all parts of the cell, surrounding all of the organelles.
5: Cytoskeleton | This is a computer generated photo of a Cytoskeleton. | Just as the name sounds, the cytoskeleton helps keep the shape of the cell. | The primary function of the cytoskeleton is to help the other organelles keep there movement in tacted. Also,cell locomotion and muscle fiber contraction could not take place without the cytoskeleton. | Cytoskeleton is anywhere another organelle is. | Cytoskeleton almost looks like a spider web. The ''webs'' are all connected
6: Nucleus | Computer generation of a nucleus. | The nucleus's main function is to control what the other organelles do. | The nucleus holds the cell's DNA and the "recipes" for making the proteins. | The nucleus is like the control room of the cell. It gives all of the other organelles instructions on what to do. | The nucleus is the center of the entire cell.
7: Nucleolus | A close up of a nucleolus. | The nucleolus's main function is to make ribosomes. | Ribosomes made by the nucleolus leave the nucleus and attach to the rough Endoplasmic Reticulum. | If ribosomes are factories, the nucleolus is the big factory that makes the machinery used in factories. | The nucleolus is in the nucleus
8: Ribsomes | A photo of ribsomes. | Ribosomes are made up of proteins and RNA | Ribosomes can be found either attached to the Rough Endoplasmic Reticulum or floating freely in the cell. | Ribosomes make the proteins for the cell. They are very important. | Ribosomes are like factories. They make proteins and send them to the ER. | Proteins made by free-floating ribosomes float around in the cytoplasm.
9: Endoplasmic Reticulum | Pointing out the endoplasmic recticulum. | There are 2 different ER- Rough and Smooth. | Proteins made by ribosomes go into the Rough ER, where enzymes cover them in sugars. | There are almost no ribosomes on the Smooth ER. The Smooth ER's job is to make lipids and break down toxins. | The Rough Endoplasmic Reticulum is like a tailor for proteins. The Smooth ER is like a lipid factory/hazmat unit. | The ER is found close to the nucleus.
10: Golgi Apparatus | Photo of a Golgi Apparatus. | The golgi apparatus look like a big stack of pancakes. | The golgi apparatus function is to make materials manufactured by the cell, then package those products into small structures called "Golgi vesicles." This is how the golgi apparatus helps the cell. | The Golgi is like the cell's mail room.
11: Vacuoles | Point of origan of vaculoes. | A vacuole is a membrane organelle which is present in all plant cells and some protist, animal, and bacterial cells. | Vacuoles are closed compartments, like storage spaces, which are filled with water containing inorganic and organic molecules including enzymes in solution. | Vacuoles also play a major role in autophagy, maintaining a balance between production and turnover, of many substances and structures in certain organisms. | The vacuoles is very large and can sometimes take up more then half of a cells volume. It's towards the inside of the cell, expanding out.
12: Lysosomes | Lysosomes placement in a cell/computer generation. | Lysosomes is a microbody that comes from the golgi apparatus. Lysosomes have digestive enzymes which, if released into the cell, would digest the vital contents of the cell and kill it. This is how it works with other organelles. | Lysosomes just look like little beads found on a necklace or bracelet. | Lysosomes divide anything inside them into their basic components. These components get used for other things.
13: Centrioles | Picture of centrioles. | Centrioles looks like noodles. They're long and slim, just like angel haired noodles. | The main function of the centrioles is to generate the cells cytoskeleton. By doing this, it helps maintain the shape of the cell. | Centrioles form to make centrosomes, which is where microtubles are produced.
14: Mitochondria | Processes of Mitochondria. | The main function of the mitochandria is toperform the aerobic portions of aerobic cellular respiration, the essential energy-producing process of the cell. | The mitochondria are the power plants of the cell | The mitochondria turns energy from food into ATP (adenosine triphosphate) | Mitochondria produce the energy necessary for the rest of the orgalelles to function.
15: Chloroplasts | This is what a chloroplast looks like. | Chloroplasts are found only in plant cells. They contain chlorophyll. | Chloroplasts give plants their green color. | Photosynthesis occurs in the chloroplasts. Solar energy is turned into chemical energy. | Chloroplasts are like solar panels, taking energy from the sun and turning it into energy that the cell can use.
16: Cilia/Flagella | Diagram of Cilia. | Cilia and flagella are what cells use to move either themselves or other cells. | In men, flagella allow sperm cells to swim. In women, cilia move egg cells from the ovaries to the uterus. | Cilia and flagella are found attached to the outside of the cell | Cilia and flagella are part of the cytoskeleton. | Cilia is another part of the cell that looks like a noodle.
