Endoplasmic Reticulum

The endoplasmic reticulum is a type of cell organelles which forms a series of flattened membrane-bound sacs in the eukaryotes. It serves various functions in the cell. Most importantly it folds, modifies and transports proteins. All eukaryotic cells contain endoplasmic reticulum. There are two types of ER: rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum […]

Structure and Function of the Cell Nucleus

The cell nucleus is the most prominent part of the cell. It is derived from Latin word nucleus which means ‘kernel’. It is a highly specialized organelle of the cell. It constitutes most of the genetic material of the cell and coordinates the activities of the cell like growth, metabolism, and cell division. Almost all eukaryotic cells […]

Cell Organelles

All organisms are composed of cells and there are many smaller structures in the cells called cell organelles. It can be called the division of labor among cells, which allows them to carry out their functions. Cell organelles and their Structure Nucleus The nucleus is the largest organelle in the cell which is surrounded by a […]

Prokaryotes and Eukaryotes

The distinction between prokaryotes and eukaryotes is considered very important among organisms. Prokaryotes do not possess a membrane-bound nucleus while eukaryotes do. All cells are classified into prokaryotes or eukaryotes depending on either their nuclei and other organelles are bound to a membrane or not. There are many other differences between prokaryotes and eukaryotes which will […]

Chromosome Structure and Function

What are Chromosomes? Chromosomes are the threadlike structures found in the nucleus of almost all organisms. Chromosomes are made up of protein and DNA. They are passed from parents to offspring and contain all the instructions required to produce a complete individual. Every species has a specific number of chromosomes in their nucleus. For example, humans […]
