BINOMIAL NOMENCLATURE
This is how species are named

THE KINGDOMS
We can classify living things into 5 kingdoms
MONERA KINGDOM
UNICELLULAR
AUTOTROPHIC AND HETEROTROPHIC
FUNGI KINGDOM
UNI OR MULTICELLULAR
HETEROTROPHIC
PLANTS KINGDOM
MULTICELLULAR
AUTOTROPHIC
ANIMAL KINGDOM
MULTICELLULAR
HETEROTROPHIC
PROTISTA KINGDOM
UNI OR MULTICELLULAR
AUTOTROPHIC AND HETEROTROPHIC
ALL KINGDOMS HAVE EUKARYOTIC CELL EXCEPT MONERA KINGDOM
MONERA KINGDOM
ALL ARE BACTERIA
SOMETIMES MOVE THANKS TO FLAGELLA
ALWAYS UNICELLULAR
PROKARYOTIC CELL
ASEXUAL REPRODUCTION
SOME BACTERIA ARE DETRIMENTAL, WHILE OTHERS ARE BENEFITIAL TO US
BACTERIA TYPES :
COCCI
BACILLI
SPIRILLA
VIDRIOS
FUNGI KINGDOM
ALL HAVE EUKARYOTIC CELL WITH CELL WALL COMPOSED OF CHITIN
THE BODY OF THE FUNGI IS CALLED MYCELIUM, AND IT IS MADE OF TUBES CALLED HYPHAE
FUNGI REPRODUCE BY SPORES, PRODUCED IN THE FRUITING BODY, AND THEY NEED HOMIDITY
THE NUTRITION OF FUNGI IS HETEROTROPHIC, BUT THERE ARE DIFFERENT GROUPS :
SAPROPHYTES:
- Feed on organic matter, for example a mushroom
PARASITES: Produce diseases called mycosis, for example the candida
SYMBIONTS: Relation of 2 individuals that obtain mutual benefits
PROTISTA KINGDOM
ALL HAVE EUKARYOTIC CELL, AND CAN BE UNICELLULAR OR MULTICELLULAR
THERE ARE TWO MAIN GROUPS :
ALGAE
AUTOTROPHIC
DO THE PHOTOSYNTHESIS
AQUATIC ENVIROMENT
PROTOZOA
HETEROTROPHIC
IN AL POSSIBLE ENVIROMENTS
UNICELLULAR
