Question

How does bacteria grow?

Answer 1

Budding or binary fission (and rarely multiple fission)

Explanation:

Bacteria grow either through budding or through binary fission.

In binary fission a copy is made of the DNA, RNA, proteins etc. The volume of the cell increases at the same time. When the synthesis is complete a ring appears in the middle and cleaves the cell in two equal parts, creating 2 cells.

Budding is the process in which a small part of the parent cell is detached from the parent. This smaller cell contains a copy of the DNA and will start growing on its own to full size.

Multiple fission is a bit similar to binary fission. The main difference is the amount of daughter cells produced.
