02.03 Cell Structure And Function Assignment

For a plant cell, the nucleus, without a doubt, is the most important organelle; but in the animal cell, the most vital structure is the mitochondria.

Cytoplasm of eukaryotic cell is partitioned by organelle membranes. Organelles together form the endomembrane system.

Endoplasmic reticulum (ER) – Endoplasmic reticulum is a branching network that fills the cell interior. There two types of ER: Smooth endoplasmic reticulum (SER) – Synthesis of lipid, glycogen and steroids (e.g. cholesterol and testosterone).

Serves as the cell 's skeleton. It is an interior protein system that gives the cytoplasm quality and adaptability. The cytoskeleton of all cells is made of microfilaments, halfway fibers, and microtubules. Muscle cells contain these cytoskeletal parts in addition to thick fibers. The fibers and microtubules of the cytoskeleton frame a dynamic system whose ceaseless rearrangement influences cell shape and capacity.

The main function of the Endoplasmic Reticulum is to produce, store and transport proteins and lipid to most of the cell organelles. The Endoplasmic Reticulum is a large organelle that looks like sheets of folded membranes.

The smooth endoplasmic reticulum is responsible for production and packaging of lipids and steroids. (Plant Cell Anatomy, n.d.)

A few seconds later, the nurse and the resident came into the room. “We’re ready for your scan, Mr. Dusty,” the nurse said. “One more thing before we continue.” The nurse looked at Vinyl. “You’re Vinyl, correct? Dusty’s daughter?”

So I, the cell membrane should be your new leader and take the title of ‘ most important organelle’ because I have protected the cell since forever and get little credit and since I know how it feels to be un appreciated for all that you do I will support the organelles who don’t get the credit they

P1 – Describe the microstructure of a typical animal cell and the functions of the main cell components. A typical animal cell is seen as a tiny, three dimensional sac which is in fact made up of many components, each as important as the other. The microstructure of an animal cell was in fact uncovered mainly through the use of both cell fractionation and electron microscopy. Each main component has its own, individual function which helps a cell to function and maintains the cell membrane. The components that I will be describing include the cell membrane, nucleus, cytoplasm, mitochondria, lysosomes, Golgi bodies, centrioles, endoplasmic reticulum (both smooth and rough) and ribosomes.

My candidate, toils everyday to make sure that all of the other sloppy organelles don’t damage themselves by bumping into each other. Unlike the other the organelles Cindy Cytoplasm isn’t reckless. An additional trait that sets Ms. Cytoplasm apart

Good morning. This is Larry Lysosome here. I work at The Cell Corporation. My job here at Cell Co. is to recycle the other malfunctioning parts of the cell and return their nutrients back into the cell. I write to you because I am aware that you will soon be firing some employees here at Cell Co. and wanted to inform you that Cell Co. would be a complete mess without me (no pun intended). I'm a vital part of the corporation and it would be nearly impossible for the other organelles as well as you Mrs.Eukaryote to work properly without me. So I ask that you take a moment to listen to me and consider what I have to say.

Endomembrane System- is a system of membrane based organelles within the eukaryotic cell that are either in direct contact with each other or communicate through the use of vesicles. A primary role this system plays in intracellular processes is treatment and transport of proteins. The membranes and organelles include the nuclear envelope, the endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles, and peroxisomes.

Endoplasmic Reticulum - a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. The endoplasmic reticulum is like the radio throughout the school because it connects to every building on campus. When Mr. Duncan announces anything that is going on, the entire school can hear what is happening/going on. There is a radio in almost every classroom on the CDS campus.

Many cells are filled with a complex network of tube like things known as the endoplasmic reticulum. The endoplasmic
