Relate the structure and function of cell organelles

        Cells are like cities with intricate organelles 'living and working' in it. There are basically two kinds of cells, namely Prokaryotic and Eukaryotic. Both plant cells and animal cells are eukaryotic while prokaryotic cells are simplier organisms that possess non-membrane bounded organelles. In most cells they contains the following organelles which carry out unique functions and allow cells to work properly.

        To start off with, nucleus is a large roundish organelle enclosed by a double membrane with numerous openings, namely nuclear pores, for nuclear traffic. It contains chromosomes and one or more nucleoli. Nucleolus is a spherical site where ribosomes are formed. Chromosomes contain DNA which tends to be packed in form of chromatin. Only during interphrase (a stage before a cell divides in a cell division process), chromosomes will be unravelled for easier replication. Tiny, hollow cylinders of protein called centrioles form a network of spindle fibres in the nucleus during nuclear division to pull chromosomes apart. The inner membrane of nucleus will break down and allow chromosomes lying freely in cytoplasm. DNA contains the genetic information and control the synthesis of protein.

        Each cell contains millions of ribosomes. They are very tiny, non-membrane bounded organelles made of protein and RNA which consist of two sub-units that come together during protein synthesis. Ribosomes are distributed throughout the cell. Some of them are embedded in rough endoplasmic reticulum to translate a protein secreted into it while some flows freely in the cytoplasm for making protein that stays in the cell.

        Fused to the nuclear membrane is the endoplasmic reticulum. There are two types of endoplasmic reticulum: the smooth endoplasmic reticulum (sER) and the rough endoplasmic reticulum (rER). As implied by ...

This is a very well researched and concisely written report. 1. Improvements could be made by including images to illustrate concepts 2. The use of key terms and language is excellent 3. The conclusions is very brief *****
