25.5.1: Binomial system of nomenclature The scientific name of a species consists of two words; both words are italicized but only the first word is capitalized. For example Homo sapiens, the scientific name for humans, indicates that humans are one kind of ape in the genus Homo.Benefits of the binomial nomenclature system include: 1) It is much easier to identify a species with this system. 2) Information about a species can be obtained easily online with just two words. 3) It’s obvious if two species are members of the same genus. 4) All countries use the same name, avoiding difficulties of translation. 5) Scientific names remain the same through time (unless there is a compelling reason to change it).

10Plant PhylaRootsStemsLeavesReproductive partsAngiospermophyta (flowering plants)True roots that can be wide-spreadingStems have support tissue and can therefore grow very tall.Vast diversity of leaf shapes.Produce flowers. Seeds not in cones.Coniferophyta (conifers)True roots that grow deep.Stems have support tissue and can therefore grow very tallWater-conserving leaves (needle-shaped,thick waxy cuticle, few stomata)Do not produce flowers. Seeds protected in cones.Filicinophyta (ferns)True roots present but simple.Short stems that grow at, or just under, the ground surface.Leaves have numerous subdivisions and sporangia underneath.Do not produce seeds Do not produce flowers. Produce spores.Bryophyta (mosses)Lacking true roots; have rhizoids insteadLacking stemsLacking leaves
11Plants are a diverse group of eukaryotic organisms Plants are a diverse group of eukaryotic organisms. Describe the different characteristicsof the bryophyta, filicinophyta, coniferophyta and angiospermophyta.  M10/4/BIOLO/SP2/ENG/TZ1/XX
12At least one characteristic from each group is needed for maximum credit. bryophyta have no roots / only have rhizoids;bryophyta have simple leaves/stems / only a thallus;bryophyta produce spores in capsule;byrophyta are nonvascular;bryophyte exhibit (pronounced) alternation of generations / a significant gametophyte generation;filicinophyta have roots, stems and leaves;filicinophyta (often) have divided/pinnate leaves;filicinophyta produce spores in sporangia/spores on the undersides of leaves;filicinophyta exhibit alternation of generations;filicinophyta have primitive vascular tissue / no true xylem and phloem;coniferophyta have woody stems;coniferophyta (often) have narrow leaves/needles/scales;coniferophyta produce seeds in cones/unenclosed seeds;angiospermophyta have flowers;angiospermophyta have ovules in ovaries;angiospermophyta produce seeds (with hard coats) in fruits; [9 max]
13Using simple external recognition features, distinguish between the plant phyla bryophyta and angiospermophyta.  M10/4/BIOLO/SP2/ENG/TZ2/XX+
