Flashcards

Binary Fission

The most common asexual reproduction method in bacteria, where a single parent cell replicates its DNA and divides into two identical daughter cells.

Budding

A rare form of bacterial reproduction in which a bulge forms on the parent cell, grows to full size, then detaches as a daughter cell.

Endospores

Resistant, dormant cells formed within some bacteria, allowing survival in harsh conditions. They have low metabolic activity and are protected by multiple layers.

Sporulation

The process by which a bacterium forms an endospore, creating a resistant cell within itself.

Study Notes

Bacteria Reproduction

Bacteria reproduce asexually, lacking true nuclei and sexes
They reproduce by binary fission (splitting into two), budding (bulging and detaching), or spore formation (endospores)
Binary fission is a rapid process, doubling bacterial numbers every 20 minutes under ideal conditions
Budding is a less common method where a protrusion grows to equal the parent cell's size and then detaches
Endospores are resistant resting cells. They form at the end of active growth and have low metabolic activity
