This page lists topics related to microorganisms and protozoa, including bacteria, unicellular protozoa, and multicellular pond life.
Amoeba is a group of primitive protists. They move through extension and retraction of their “false feet”, thus changing their shape as they move. This type of movement is called amoeba movement.
Synura is a small group of golden-brown algae found mostly in freshwater. They are covered in silicate scales and tends to aggregate and assemble into a cluster.
Daphnias, also called water fleas, are small planktonic crustaceans. Its body is usually 0.2–6.0 mm long and enclosed in a transparent shell.
Bacteria and archaea are single cell prokaryote. They are similar in sizes, shapes, reproduction, and habitats. They differs in cell wall and membrane compositions.
Archaea are single cell organisms without a nucleus and other membrane-bounded organelles. Archaea are not closely related to the bacteria but are more closely related to the eukaryotes.
Bacteria are single-celled microorganisms. Because they don’t have nuclei or membrane-bound organelles, they are classified as “prokaryotic cells”.
A fragment of planarian can regrow into a new animal in two weeks. Genes such as notum and wnt1, instruct the planarian where to grow a head and a tail.
Planarians are a group of free-living flatworms. They have a remarkable ability to regenerate an entire worm from just a tiny fragment of the original.
Hydras are classified under the phylum Cnidaria; some of its relatives are jellyfish and sea anemones. A hydra has many tentacles around the mouth opening.
Red algae, also called Rhodophyta, are a large group of eukaryotic organisms that can photosynthesis. Their red color results from the red pigments – phycobilins, which are absent in green algae.
