Bacterial Cells

Bacterial Cells -

Bacteria as seen later, can be broadly divided into two major groups based On their Gram staining characteristics such as Gram positive and Gram negative.

The Gram staining technique, the most widely used differential staining technique employed in bacteriology was first developed by

Christian Gram in the 19th century and is used primarily to divide bacteria into two broad groups.

Most bacteria have at least two structures around the cytoplasm namely the cell wall (envelope) and the cytoplasmic membrane.

Some may have additional components such as the outer membrane as in the Gram negative bacteria, a capsule and slime.

Some bacteria which are motile have surface appendages with the aid of which they can move.

In addition, some others such as the Gram-negative bacteria have short hair like structures called the pili (fimbriae).

These are not essential for the growth and survival of the bacterial cells.
