what are the drawbacks of the old twi kingdom classification
-bacteria was excluded because they can not be called plants as they are prokaryotic
-orrganisms which have both animal and plant-like features are excluded(eg-euglena)
-fungi are also not plants
what is five kiingdom classification
-monera
-protista
-fungi
-plantea
-animalia
differentiate between monera and protista
monera
-prokaryotic
-unicellular
-no membrane bound organelles
eg-bacteria
protista
-eukaryotic
-unicellular
-contains unicellular non green heterotrophic and autotrophic organisms
eg-euglena
kingdom fungi
-eukaryotic
-achlorophylous
-multicellular
-saprophytic
-made up of thread like hyphae
-there are many nuclei distributed in the continuous cytoplasm
kingdom plantae
-eukaryotic
-autotrophic
-multicellular
divided into
-thallophyta
-bryophyta
-pteridophyta
-gymnosperms
-angiosperms
differentiate between thallophyta and bryophyta
thallophyta
-autotrophic
-primarily aquatic
-multicellular algae
-thallus like body(root,stem and leaf cannot be distinguished)
-eg;seaweed
bryophyta
-autotrophic
-has root lik[rhizoid]stem like[caulid]and leaf like [phyllid] structures
