Bacteria like organisms but live in extreme environment/also known as extremophiles/methanogenic/they are classified based on their habitat

means ancient or primitive

Live in absence of oxygen

salt loving

Cold loving

True bacteria/the most diverse and widespread prokaryotes/the most versatile organisms

Thread –like strands

Spherical shape

Rod – shaped

Spiral shape

Animals, fungi, plants and protists

The most primitive forms but the most diverse among unicellular eukaryotic organisms.

Causing red tide

They are saprophytic, parasitic, predatory, symbiotic with vegetative filament (hyphae) form spores with chitin (polysaccharide) provide numerous drugs

Imperfect fungi

Common molds

Phylum Glomeromycota

Sac fungi

Club fungi

They are multicellular eukaryotic organisms, autotrophic/producers.

Vascular plants with tracheids.

Primitive forms of plants that lack of tracheids

Spores produced by seedless plants

Underground stem of seedless plants.

The biggest kingdom/multicellular organisms without cell walls or chlorophyll/ they are heterotrophs

They are sessile as adults( stationary organisms) ex. Sponge

Radially symmetrical aquatic animals, some are sessile, they have nematocysts(e.g jellyfish, sea anemones,corals, and hydra)

Flatworms, bilaterally symmetrical body (e.g. planaria, flukes and tapeworms)

Roundworms ( e.g. ascaris)

Segmented worms (e.g. earthworms,and leeches)

Bilaterally symmetrical ( e.g. rotifers)

Soft – bodied unsegmented animals(e.g. snails, clams, squids, octopuses)

Spiny skinned organisms, biradially symmetrical animals. (e.g. starfishes, brittle stars, sea urchins, and sea cucumbers)

Jointed legs animals with exoskeleton. ( e.g. crabs, lobsters, spiders, centipedes, insects)

Bilaterally symmetrical body, with pharyngeal slits, presence of notochord, dorsal hollow nerve cord, with backbone. (e.g. tunicates, lancelets, fishes, amphibians, birds and mammals)
