Cell membrane: The cell membrane surrounds the cytoplasm of a cell and its job is to protect the inside of a cell by only allowing certain substances into the cell and keeping other substances out. It also helps to support the cell and maintains its shape. Nucleus: This is the biggest part of the cell and is the part of the cell which acts like the brain. It is not always in the middle of the cell but will be placed within the cytoplasm. In some cases a cell may have many nuclei and these are

Golgi Apparatus: Dionysus‚ or as the campers call him‚ “Mr. D‚” is in charge of the strawberry service the camp runs and the weapons that the campers make. He processes the swords and makes sure they are fit to send outside of the camp‚ and controls the exporting of the strawberries‚ just as the Golgi Apparatus processes lipids and proteins before they exit the cell.

to store and distribute gasoline to the engine of the car. The Golgi Apparatus can be compared to something like a car filter. The main purpose of the Golgi Apparatus is to take in certain productions from the rough endoplasmic reticulum and checks to make sure that none of the chemicals are in their wrong place. If the Golgi apparatus does find something in the wrong place it will send it back the rough ER. A Golgi apparatus is like the filter of a car because like a filter it chooses which

Introduction For this assignment I will have to talk about the organisation‚ e.g. cells‚ tissues‚ organs and systems. And the cells‚ e.g. cell membrane‚ nucleus‚ cytoplasm; organelles- mitochondria‚ smooth and rough endoplasmic reticulum‚ golgi apparatus and lysosome. Organisation; Every individual is composed of billions of microscopic units called cells. The cells carry out vast numbers of chemical reactions and processes that make up the essence of life itself. Cells rarely exist in isolation;

Carbon dioxide levels inside the cells will rise and the pH will begin to drop‚ the mitochondria have no more oxygen and glucose to make ATP. The cells began to die. The cells become leaky‚ because the active transport pump shuts down. Sodium began leaking into the cells and potassium leaked out. The chemical gradients diminish‚ the heart

In this report i will be writing brief description on the functions of the main cell components of the body cell. The cell membrane : is something that lets some things in and some things out of the cell. It is an outer cover for the cell. If the cell membrane was non existences the cell would spill all over the place. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell‚ while keeping other substances out. It is composed of a thin

This could be a hospital or rehab center in our city. Golgi – Every city needs a post office where information/mail/products manufactured within the city can be properly sorted and distributed.
