Parts of The Cell

There are 3 parts different parts of a cell namely nucleus, cell membrane, and cytoplasm. To understand them better, our teacher made us look at cells as a miniature city. 

Cell membrane or some other people call it selectively permeable membrane acts as a protective covering of the cell. It is also responsible for allowing materials in and out if the cell. We can think of it as the city limits.

Nucleus is described as the brain of the cell. It dictates the activities of the organelles in the cell.  We can consider it as to be the City Hall; a control center.        

Cytoplasm is a special environment that contains organelles of the cell in order to survive. Ribosomes are made of RNA and assist the production of enzymes and other proteins that are needed for cell repair and reproduction. It is considered as the building material suppliers for modelling and repair. Centrosomes are considered as the building contractors that builds new structures needed to replace old ones. Mitochondrion acts as a power plant to provide body’s energy needs for cellular repair and reproduction.  Endoplastic Reticulum is a series of channels set up in the cytoplasm it serves as the main structure for travel is a road system. Golgi apparatus receives the proteins and further process and stores it as shippable product. Lysosomes are the ones that take care of cleaning up intercellular debris and other waste.

I have learned this through my teacher’s good ways of teaching. He showed pictures and images of the cell and made an activity which I really liked. He explained it in a way that anyone could understand it. He always ensures that everyone in his class would love to participate in the discussion.  ^_-
