Archaebacteria and Eubacteria

ProtistaProtists – single celled or simple multicellularEukaryotes – contain a nucleus, organellesEvolved from ancient bacteria.Do not “fit” in any other kingdom

Examples: Protozoans – animal like Algae – plant like

FungiComplex, multicellularDo not photosynthesize.Absorb nutrients from substances in their

surroundings.Use digestive juices to break down

substances.

Examples : Molds Mushrooms

PlantaeEukaryotic – contain cell wallsVary in size and form.Make food through photosynthesisExposed to sunlight – found on land or in

water where sunlight can penetrate.Most living things get nutrients from plants.Plants are producers.Provide a habitat for other organisms.

AnimaliaComplex, multicellularLack cell wallsUsually move aroundRespond quickly to their environmentSpecialized sense organs.Dependent upon organisms from other

kingdoms.Plants – food sourceBacteria or fungi – recycle nutrients found in

dead organisms.
