PRELIM 04 - Studying Microorganisms in the Living State Flashcards
Swedish physician, botanist, and zoologist who created a new system of classification for all living things
Carl Linnaeus
Carl Linnaeus’ first attempt at classifying plants and animals was published in 1735 as __________
Systema Naturae
In the 18th century, Carl Linnaeus divided nature into 3 kingdoms, __________, __________, and _________
Regnum Animale (Animal kingdom), Regnum Vegetabile (Plant kingdom), Regnum Lapideum (Mineral kingdom)
He proposed a third kingdom of life, Protista, and included all unicellular organisms in it
Ernst Haeckel
He proposed the 5th kingdom, fungi
Robert Whittaker
Refers to organisms that makes its own food
Autotrophic
Refers to organisms that feed on other living things
Heterotrophic
Are organisms having only one cell
Unicellular
Are organisms having two or more cells
Multicellular
Are organisms that needs oxygen
Aerobic
Are organisms that does not use oxygen
Anaerobic
The most evolved kingdom; are multi-celled, heterotrophic eukaryotes with aerobic respiration, sexual reproduction, and the ability to move
Kingdom Animalia
2 large groups of kingdom Animalia
Vertebrates, Invertebrates
One of the oldest kingdoms; characterized by its immobile, multicellular, and eukaryotic nature
Kingdom Plantae
Kingdom that includes multicellular aerobic heterotrophic eukaryotes; have chitin in their cell walls
Kingdom Fungi
Kingdom that is the most primitive of all the eukaryotes; includes those eukaryotic organisms that are not deemed to be animals, plants, or fungi
Kingdom Protista
Means that it contains the common ancestor but not all its descendants
Paraphyletic
Kingdom that includes microscopic living things and groups together the prokaryotes; present in all habitats and is made up of single-cell things with no defined nucleus
Kingdom Monera
2 ways to prepare samples
Wet mount technique, Hanging drop technique
The random movement exhibited by particles suspended in liquids due to the bombardment of water molecules
Brownian motion
An independent movement brought about by different mechanisms of self-propulsion
True motility
Technique where the specimen is placed directly on the slide
Dry mount technique
