SCIENCE
VERTEBRATES
Have back bones FISHES -Aquatic animals wich move using fins
and breath through gills Examples: Bony and cartilaginous fishes Amphibians -Animals with well developed lungs that
can live both land and in water Examples: frogs,toads, and others
VERTEBRATES
Reptiles -Cold-blooded animals with dry and
scaly skin Example: Snakes, crocodiles, and
others Birds -Animals with feathers and beaks Examples: birds, and fowls
VERTEBRATES
Mammals -Animals covered with hair and skin Examples: cattle, primates and others
INVERTEBRATES
Poriferans Ocean dwelling with perforated bodies Examples: Sponges Cnidarians Animals with stinging tentacles Worms Animals with elongated bodies that
are flat Examples: roundworms
INVERTEBRATES
MOLLUSKS Soft bodied animals covered by shells. Example: Snails, tahong, octupuses and
squids ARTHROPODS Jointed leg animals Examples: butterflies, dragonflies ECHINODERMS Spiny skinned animals Examples: Sea stars, sea urchins.
ENDANGERED ANIMALS
Extinct A species of a plant or animal that is no
longer living Examples: Dinosaur Endangered A species that is in imediate danger of
becoming extinct and needs protection to survive
Examples: Tarsier, Elephant(tusks) ,Eagle
ENDANGERED ANIMALS Threatened A species is like to become endangered if it is not
protected
Ways that Species become endangered: Habitat loss Illegal killing Competition with other species Disease Predation Pesticides, pollution
6 animal kingdoms
Kingdom Eubacteria Includes true bacteria and blue green algae Called prokaryotes Reproduce asexually Kingdom archaebacteria Prokaryotes They are biochemistry and genetic compositions Kingdom protista Eukaryotes Reproduce either sexually and asexually
6 animal kingdoms Kingdom Plantae Multicellular eukaryotic organism Autotrophs Have clorophyll Kingdom fungi Saprophytic(most) Predatory(others) Sybionts(others) Reproduce sexually and asexually Cell wall contains chitin Multicellular eukaryotic organism
6 animal kingdom
Kingdom animal Multicellular eukaryotic organism Without cellwalls and chlorophyll Hetrotrophs Most have body systems Biggest kingdom 9-10 million species
Plant cell
Green Less parts Central
Vacuoles Square like Chlorophyll Have cell

Animal cell
Brown/red More parts Small
vacuoles No chlorophyll No cell wall

Gymnosperms
Phylum Coniferophyta Called conifers Needle leaves Most of the evergreen trees Phylum Cycadophyta Called cycads Palm like leaves Evergreen trees and shrubs Lives in tropics
Gymnosperms
Phylum Ginkgophyta Called ginkgos Gymnosperm shrub or vine with some
angiosperms characteristics Phylum Gnetophyta Called Gnetales
Angiosperms
Class Monocotolydon Embryo with 1 seed leaf Parralel in leaf veins Flower parts in 3 Vascular bundles
scattered randomly
Angiosperms
Class Dicotyledon Embryo with 2 seed leaves Leaf veins in a net-like
pattern Flower parts in 4 or 5 Vascular bundles in a ring
pattern
SEEDLESS PLANTS
Mosses and liverworts Small Live in bark, rocks and soil No vascular system Must live in wet places No true roots, stems or leaves Live together in large groups Covering soil or rocks Has rhizods
Importance of mosses and liverworts The 1st plants to inhabit Form a thin layer of soil when they die Help prevents soil erosion
Seedless Plants
Ferns Can grow almost everywhere Have an undergroung stem
Horsetails Small vascular plants Grow less than 1.3 m tall Grow in wet, marshy places Stems are hollow and contain cilia Pioneers use them to scrub pots and pans
Seedless plants
Club mosses 25 cm tall Grow in woodlands Unlike other mosses they have vascular
tissues
