Quiz on Cell Organelles


Quiz on Cell organelles

Organisms present in this biosphere show great diversity in size, structure and mode of life. In spite of this diversity they show unity in their basic stricture and processes. The body of an organism is formed of one or many cells. All cells are composed of a semifluid material, the cytoplasm which is enclosed by a thin coat called plasma membrane. Different subcellular component called organelles, viz., nucleus, mitochondria, golgi bodies, chloroplast, lysosomes etc are present in the cells. Striking similarities can be observed in the organelles of the cells of diverse organisms. Thus inspite of diversity, all organisms show unity in certain basic features. Read more>>
