Bacterial cells (prokaryotic cells) are structurally much simpler than eukaryotic cells and the two cell types are compared in Table 3.2. They consists of various cell surface structures, cell wall, plasma membrane, many cytoplasmic inclusions, and the bacterial chromosome (nucleoid). Except some, all structures do not occur in every genus.

Bacterial cell Structure and Function 1. Capsule:. Capsule is 0.2µm thick viscus layer outer layer to the cell wall. Capsule is 98% water and 2%... 2. Flagella:. It is 15-20 nm hair like helical structure emerges from cell wall. Flagella is not straight but is helical. 3. Pili or fimbriae:. Pili are ...

Bacterial Cell Prokaryotic cells are simple in structure, with no recognizable organelles. They have an outer cell wall that gives them shape. Just under the rigid cell wall is the more fluid cell membrane.

Bacteria are all single-celled. The cells are all prokaryotic. This means they do not have a nucleus or any other structures which are surrounded by membranes. Larger bacterial cells may be visible...

The cell surface fimbriae (fibrils) are evident. The bacterial cell wall is seen as the light staining region between the fibrils and the dark staining cell interior. Cell division in progress is indicated by the new septum formed between the two cells and by the indentation of the cell wall near the cell equator.
