The 5 Kingdoms - Classification

Animalia (Animal Kingdom): Comprises multicellular organisms; they can move and do not produce their own food, consisting of animal cells.
Monerans Kingdom: Includes unicellular organisms primarily made up of bacteria; these organisms absorb nutrients from external sources and can be beneficial or harmful.
Robert Hooke: Notable for discovering cells by examining a thin slice of cork under a microscope, laying the groundwork for cell theory.
Fungi Kingdom: Mostly constituted of multicellular organisms that cannot synthesize their own food. Features include a cell wall, stem, and roots; examples are mushrooms and bread mold, with yeast as a unicellular variant.
Plantae (Plant Kingdom): Organisms possessing chloroplasts that create food through photosynthesis. They are multicellular, eukaryotic, autotrophic, and typically green.
Protista Kingdom: Encompasses single-celled organisms that do not fit in the plant or animal categories. Some perform photosynthesis, while others ingest food through absorption; examples include Euglena, Paramecium, and Amoeba.
Aristotle: An early philosopher who formulated the first formal classification system, distinguishing only between plants and animals.
Bacteria: Considered by scientists to be the oldest life forms on Earth, playing a crucial role in ecosystems.
Chitin: A crucial substance that provides rigidity and structural support; found in the exoskeletons of spiders and insects as well as in the cell walls of fungi, contributing to the texture of mushrooms.
