    “I'm super nervous to meet the coach today” she says. She drives to practice. She meets the coach Bob. She thinks in the head the coach is kinda like the chromosomes because they teach you information about softball and how to hit a softball and catch a ball. The chromosomes In the cell Helps direct cell activity and stores necessary information for building proteins. “We are going to run a baseline drill” the coach says. (The girl) says to her friends “ isn't the baseline a little bit like the Endoplasmic Reticulum of a cell?” The Endoplasmic Reticulum transports materials from one part of the cell to another part like the baseline that shows the foul ball territory and fair territory and shows where you are supposed to run so you aren't…

    the cytosol, while bound ribosomes are attached to the rough endoplasmic reticulum. Free ribosomes and bound ribosomes are interchangeable. The cell ca change the numbers depending on its metabolic needs. The ribosomes read and translate codes from mRNA. The mRNA is sent as a messenger by the nucleolus to give the ribosomes the template for protein synthesis. The ribosomes take the template and hook together amino acids to create a polypeptide chain, protein. The protein made by free ribosomes…

    Controls the cell’s activities • Controls cell reproduction Contains genetic material - DNA that makes up the genes and chromosome. The Ribosome: ~Made of dozens of different proteins as well as RNA, also found in large numbers in the cytoplasm of living cells. Ribosome are typically composed of two subunits: • Large subunit • Small subunit “ Free” Ribosome makes proteins that remain inside the cell, “Bound’’ Ribosome make proteins that are exported from the cell. ~Protein Synthesis…

    Rough Endoplasmic Reticulum and Smooth Endoplasmic Reticulum: interconnected membranes that are a part of the cell. Vacuole: food is digested here. 3. Discuss the purpose of doing the experiment. Why are you going to do this lab and why is it important? The students will begin to recognize what the cell is comprised of, and how it functions. The students will be able to distinguish the difference between animal and plant cells. This lab is important because we have contact with cells in our…

    Sarcolema

    • 2 Pages

    Within the skeletal muscle cells, there are many organelles. Each cell contains a plasma membrane called the sarcolemma, covering the outer surface of the cell (Ivy Rose). The sarcolemma protects the muscle cell and allows for its shape to be kept. From the sarcolemma, tunnel-like extensions called transverse tubules pass through the muscle fiber (Ivy Rose). These transverse tubules connect the sarcoplasmic reticulum with the sarcolemma (Graham and Parker 117). The sarcoplasmic reticulum is a…

    through the chromatin and into the nucleolus. The structure of the nucleolus allows easy access for the proteins, as well as an easy exit for the ribosome subunits. The chromatin that surrounds the nucleolus contains both DNA and proteins. When the cell is dividing the chromatin, which is a mess of DNA strands, start to curl. After they have finished curling you can see clear, organised chromosomes. The cell divides when each of these chromosomes replicates itself through mitosis. On the outside…

    In a cell there are many organelles to help keep the cell functioning. In the cell you could have a cell wall, cell membrane, ribosomes, cytoplasm, flagella, cilia, nucleus, nuclear membrane, nucleolus, chloroplast, Golgi apparatus, lysosomes, mitochondria, plastid, rough endoplasmic reticulum, smooth endoplasmic reticulum, vacuole, and a vesicle. Everyday items can represent many of the organelles. One example of this is by looking at a house. In a house you have a fence. The fence in your…

    of the cell. I finally made my way over to the Centriole it is a bright gold color and it was about 4 feet tall. It had about 6 different tubes and I learned that it is used in cell division. It was so cool, then I realized there were about four centrioles floating right above me moving slowly through the cytoplasm’s gooey texture. I saw some little Silver organelles floating around cleaning up worn out cell parts and food particles. I learned in science that these organelles are called…

    as repairing or directing chemical processes. Ribosomes could be found around the cell or next to the endoplasmic reticulum. Cytoplasm is made up of cytosol. In prokaryotes all the cell content is within the cytoplasm whereas with eukaryotes the nucleus is separate from the cytoplasm. The cytoplasm is about 80% water and usually colorless (4). Eukaryotes only contains the following: Mitochondria are found in both plant and animals cells and are shaped like a rod. A mitochondrion contains outer…

    are covered with ribosomes which create proteins, the proteins are then carried by the cisternae within the endoplasmic reticulum to their place within the cell. While the ribosomes in this case are attatched to the endoplasmic reticulum, this is not their only position, they can also be found freely within the cell cytoplasm (the area within the cell that contains the cell organelles) The S.E.R is in charge of storing, and secreting non-protein products such as carbohydrates and lipids etc.…
