Prokaryotic vs Eukaryotic Chromosome Prokaryotes and Eukaryotes are the two major domains of living organisms. This classification is on the basis of the features of their cellular features primarily the nature of membrane bounded organelles and organization of the genetic materials. Both prokaryotes and eukaryotes contain the genetic materials which […]

Bacterial Cell Surface Appendages
Flagella vs Fimbriae vs Pili of Bacteria What are cell surface appendages? Cell surface appendages (aka filamentous appendages or Extracellular Structure of Bacteria) are proteinaceous tubular or fibrous structures found on the surface of bacterial cells. They extend from the surface of the bacterial cell wall and can have many […]

Difference between Bacterial Endospores and Vegetative Cells
Endospore vs Vegetative Cell Bacterial endospores are special tough, dormant and resistant spores produced by some Gram-positive bacteria of during unfavorable environmental conditions. They help the bacteria to endure the unfavorable conditions. The endospores are structurally, metabolically and functionally very different from bacterial vegetative cells. In the previous post, we […]

Bacterial Endospore: Characteristics, Structure and its Formation
What are Endospores? Bacterial endospores are special tough, dormant and resistant spores produced by some Gram-positive bacteria of Firmicute family during unfavorable environmental conditions. Endospores are developed within the vegetative cells (hence the name, endo = inside). They help the bacteria to endure the unfavorable environmental conditions. Another importance of […]

Difference between Pili and Flagella of Bacteria- A Comparison Table
Flagella vs Pili of Bacteria Both Flagellum (plural Flagella) and Pilus (plural Pili) are the filamentous proteinaceous structures found on the surface of some bacterial cells. They extend from the surface of the bacterial cell wall and can have many functions such as motility, attachment, adhesion and assisting in genetic […]
