Kingdom Monera
Kingdom Monera
Nerissa Mae F. Dadores
MONERANS * Oldest and most abundant organisms. * Unicellular organisms without a nucleus. * Prokaryotes are single-celled organisms. They are the smallest, simplest organisms. * Microscopic & Undergoes Asexual reproduction.
HISTORY
The taxon Monera was first proposed as a phylum by Ernst Haeckel in 1866. Subsequently, the taxon was raised to the rank of kingdom in 1925 by Édouard Chatton. The last commonly accepted mega-classification with the taxon Monera was the five-kingdom classification system established by Robert Whittaker in 1969.
Bacteria - small one celled monerans. * Bacteria like a warm, dark, and moist environment
They are found almost everywhere: water, air, soil , food, skin, inside the body and on most objects.
3 Shapes of Bacteria
Bacteria are classified by shape into 3 groups:
Spiral: spirilla
Rod-shaped: bacilli, bacillus
Round: cocci
7 Major Structures of a Bacteria Cell * Capsule * Cell wall * Ribosomes * Nucleoid * Flagella * Pilli * Cytoplasm
Capsule * Keeps the cell from drying out and helps it stick to food or other cells.
Cell wall * Thick outer covering that maintains the overall shape of the bacterial cell.
Ribosomes
* Cell part where proteins are made. * Ribosomes give the cytoplasm of bacteria a granular appearance in electron micrographs.
Nucleoid
* A ring made up of DNA.
Flagella
* A whip-like tail that some bacteria have for locomotion.
Pilli
* Hollow hair-like structures made of protein. * Allows bacteria to attach to other cells. * Pilli-singular * Pillus-plural
Cytoplasm * Clear jelly-like material that makes up most of the cell.
Reproduction
Prokaryotes have a single circular chromosome attached to the inside of the plasma membrane.
Asexual - Binary Fission * Prokaryotes reproduce by simply splitting in two. * The DNA is copied and the cell
