kingdom of life features of cells-
animals-
plants-
fungi-
protoctists-
bacteria-
animals- cells have a nucleus, cytoplasm, cell membrane, mitchocondria, no cell walls or chlorplasts, stores carbs as glycogen
plants- cells have a nucleus, cytoplasm, cell membrane, mitcohcondria, vacuole, chlorplasts, cell wall made of cellulose, stores carbs as starch or sucrose
fungi- cells have a nucelus, cytoplasm, cell membrane, mitocondria, cell wall made of chitin, stores carbs as glycogen
portoctist- all different to each other
bacteria- cells have a membrane, a cell wall but no nucleus

what does species mean?
a species is a group pf similar organisms that can reproduce to form fertile off spring
all living orgamisms share similar characteristics, MRS GREN

varation?
individuals of a certain species are slightly different to each other) selection pressure (not all individuals can survive e.g. due to lack of food) competition (so individuals of the species compete to survive) survival and reproduction or death (those individuals that do survive can reproducde, the survivors off spring are similar to themselves so stronger) next generation is different to previous generation (so over all the new generation is better adapted to the environment than the previous generation)
