the seven things that every living organism has - movement, respiration, sensitivity, growth, reproduction, excretion, nutrition.
how do you name a genus and species?
using the binomial system. for example - Elephas maximus - elephas is the name of the genus and its specific name is maximus.
how would you classify an organism?
using these techniques - morphology, anatomy, observing the sequences of amino acids that create protein, observing the sequence of bases that make up dna.
what are the five classification groups?
animal, plant, fungi, protoctist, bacteria
the animal kingdom contains?
vertebrates - animals that have a backbone
arthropods - that have joint legs and segmented bodies
name 3 types for vertebrates and arthropods?
vertebrates - mammals, reptiles, amphibians
arthropods - arachnids, insects, crustacaens

what is the difference between viruses and bacteria?
bacteria can be of 2 types - pathogenic and non-pathogenic, whereas viruses are always pathogenic
what is the protoctist kingdom also known as?
the dustbin kingdom
define what type of organisms come under protoctist
some of the cells have animal like characteristics and some are plant like -
plant - chorella and algae - have chloroplasts
animal - amoeba - doesnt have chloroplasts or a cell wall
what is the cell wall of a fungus cell made off
chitin
where does protein synthesis take place
in the ribosomes of a cell
which parts do animal cells and plant cells share and which parts do they not.
do - ribosomes, nucleus, mitochondria, cell membrane, cytoplasm
dont - vacuole, chloroplasts, cell wall
what is oxyhemoglobin
when the haemoglobin binds with oxygen in the red blood cell it forms oxyhemoglobin
