Virus and Bacteria

Bacteria

The most successful and simplest organisms on the planet.

Binary Fission

A method of asexual reproduction in which a bacterium divides into two identical cells.

Archaebacteria

A group of prokaryotes that can survive in extreme environments and have a different chemical composition from Eubacteria.

Eubacteria

A type of prokaryotic bacteria found in various environments with a wide range of shapes, sizes, and functions.

Cocci

Spherical shaped bacteria.

Bacillus

Rod-shaped bacteria.

Spirilla

Spiral shaped bacteria.

Halophiles

Archaebacteria that live in extremely salty conditions.

Thermophiles

Archaebacteria that thrive in extremely hot environments, often at 100°C.

Methanogens

Archaebacteria that produce methane, often found in swamps and inside the guts of animals.

Virus

A non-living infectious agent that can only reproduce inside living cells.

Reproduction of Viruses

Occurs only inside other living cells, leading to the destruction of the host cell.

Antibodies

Proteins produced by organisms that fight off viral infections.

Immunizations

Vaccines that stimulate the production of antibodies to protect against infections.

Cell Wall

A protective layer found in 90% of bacteria, providing shape and protection.

Prokaryotic Cells

Cells that lack a nucleus and membrane-bound organelles, characteristic of bacteria.

Aerobes

Bacteria that require oxygen to survive.

Decomposers

Bacteria that break down organic matter, recycling nutrients in the ecosystem.

Diplo

Arrangement of bacteria in pairs.

Staph

Arrangement of bacteria in clusters.

Strep

Arrangement of bacteria in chains.
