Living Organism Plants Vascular Animals Non Vascular Plants Vertebrates Invertebrates Very small with simple leaves, stem and no true roots Non flowering and seedless Produce spores enclosed in capsules. Non vascular plants Don’t have vascular tissues(xylem and phloem) Examples : Mosses, Liverworts Vascular plants With seeds Without seeds Flowering plants Non flowering plants Angiosperms Gymnosperms Vascular plants without seeds They Don’t have For produce spores example: flowers underside and Ferns their seeds leaves True roots stem and leaves but no flowers Seeds of gymnosperms are not enclosed in fruits Gymnosperms (Naked seeds) Seeds develop in cones For example: Pines , Cycads and Ginkgos True roots stem and leaves with flowers Seeds are enclosed in fruits Angiosperms Flowers are bright and colourful to attract insects for pollination For example: Water lotus, rice plants Vertebrates Mammals Reptiles Birds Fishes Amphibians Mammals Body covered with furs Mother feed their young ones Warm blooded Give birth to young ones For example: Lion, bat, sheep etc Birds Body covered with feathers Have beak and wings Warm blooded Lay eggs with hard shells For example: Sparrow, ostrich etc Did you find any similarity between mammals and birds? Reptiles Lungs for breathing Dry scaly skin Cold blooded Lay eggs with leathery shells For example: snake, crocodile etc Fish Tail, fins and streamlined body scaly skin and have gills Cold blooded Lay eggs without shells For example: shark , sea horse etc Amphibians Adults have lungs and young ones have gills Lay eggs in water Cold blooded Body covered with moist skin For example: frog , salamander etc Did you find any similarity between reptiles, fishes and amphibians? Exoskel eton Crustaceans Arachnids Arthropods Millipedes Jointed legs Invertebrates Without jointed legs Arthropods Centipedes Insects Invertebrates Segmented body Heads are not clear Compound eyes and have gills Crustaceans Two pair of antennae Four pair of legs Arachnids For example: For example: Hermit crab, Lobster etc No antennae Simple eyes Spider , tick etc One pair of antennae Simple eyes & carnivores Three pair of legs & have compound eyes Three body segments Head Thorax Abdomen Millipedes & INSECTS Centipedes CENTIPEDE: 1 pair of legs on each segment MILLIPEDE: 2 pair on each segment. For example: Millipedes & Centipedes For example: 1 pair of antennae and have wings Honey bee, butterfly praying mantis etc Without Jointed legs Molluscs Sponges Echinoderms Nematods Flatworms annelids Exoskeleton Jointed legs Arthropods Invertebrates Segmented body Cnidarians ROUNDWORM: Round & unsegmented body Have organs FLATWORMS: Flat and unsegmented body ROUNDWORM & Segmented body Have organs Annelids FLATWORMS ROUNDWORM: Mouth & anus FLATWORMS: Single opening for food & waste For example: ROUNDWORM: Pinworm & hookworms FLATWORMS: Tapeworm Separate mouth and anus For example: christmas tree worm, Earthworm Pinworm Christmas tree worm Hookworm Tapeworm Earthworm SPONGES: Pores for water entrance Live in water CNIDARIANS: Tentacles to attack on prey Have organs but no head Echinoderms SPONGES &CNIDARIANS For example: Don’t have any true organs Have spines on body & fiveway radial symmetry body SPONGES CNIDARIANS: Jelly fish, corals etc Separate mouth and anus For example: star fish , sea urchin etc Sponges Sea star Jelly fish Corals Sea Urchin Thank you
