E - EXCRETION
N - NUTRITION
These are the seven 7 characteristics of living things
A complete and whole living this is called an organism
5 Differences
PLANTS
MAKE FOOD BY PHOTOSYNTHESIS (NUTRITION )
ONLY MOVE BY GROWTH (MOVEMENT)
RESPOND SLOWER TO A STIMULI (SENSITIVITY)
STORES WASTE IN LEAVES AND LATER SHED (EXCRETION)
REPRODUCE BY PRODUCING SEEDS (REPRODUCTION)
ANIMAL
SEARCH FOR FOOD (NUTRITION)
ABLE TO MOVE FROM PLACE TO PLACE / CHANGE POSITION (MOVEMENT)
RESPONDS FASTER TO A STIMULI (SENSITIVITY)
GET RID OF WASTE FROM THEIR SKIN (sweat) OR URINE (EXCRETION)
REPRODUCE BY LAYING EGGS (REPRODUCTION)
Stimulus / stimuli - anything is the environment that causes change in the surroundings
Classification System
Kingdom 2. Plant 3. Animal 4. Bacteria (Monera) 5. Protist 6. Fungi
Kingdom is the largest group
Order of the kingdom
Phylum → Class → Order → Family → Genus → Species
Cart Linnaeus- responsible for the classification system
Animal kingdom consists of vertebrate (with backbone) and invertebrate (without backbone)
8 types of invertebrates
Porifera (Sponges) vase sponge tube sponge
Cnidarian (jelly fish, sea anomie,corals)
Platyhelminthes (Flatworm) tapeworm liver fluke
Nematodes (Roundworm) hookworm
Annelide (segmented worm) earthworm leeches
Arthropods (crustaceans arachnids insects myriapods)
Mollusc (snail slug conch octopus)
Echinoderms (starfish sea urchin and sand dollar)
5 types of vertebrate
Fish (boney fish cartilaginous fish)
Amphibian (frog toad salamander)
Reptiles (lizard snake turtle crocodile tortoise)
Bird (sparrow bird pigeon)
Mammal (human dog whale)
Types of temperature
Poi-kilo-thermic = temperature changes due to its environment
For example fish amphibian and reptiles
Ho-mio-thermic = body is at a constant temperature (they don’t depend on their surroundings)
For example birds and mammals
