Classifying Living ThingsKingdomsMrs. HornScience 2014-2015
Protist • An organism that may have characteristics of
fungi, plants, and animals• Some have more than one cell, but MOST have
only one cell• Have a nucleus
Animal-like Protist• Protozoa are animal-like protist• Example: amoebas• Can NOT make their own food; get food from their
surroundings• Move through their environment by slipping and
sliding; others move using cilia or flagella• Live wherever there is water; can also be found in
moist soil and inside organisms
Plant-like Protist• Example: algae • Use energy from the sun to make their own food• Make oxygen• Some plant-like protist are microscopic and some
are very large
Fungus-like• Example: slime mold• Have characteristics of fungi• Get their food from their surroundings• Some reproduce through spores• Some are mobile but move very slow• Have a big effect on animals and humans (they
attack vegetable and fruit crops and animals)
Fungi Kingdom• Small, single-celled organisms or can grow to very
large masses• Have a nucleus• Cell walls are made of the same substance as the
shells of insects• Do not make OR eat food• Absorb nutrients from their environment• Decompose, or breakdown, the tissues of other
organisms• Reproduce through spores• Example: mushrooms
Bacteria • Small, single-celled organisms• Do not have a nucleus• Microscopic• More bacteria than any other living thing• They live everywhere!• Some are helpful (in your stomach- help you
digest food); others are harmful (strep throat)• Separated into 2 kingdoms: archaebacteria &
eubacteria
Acrhaebacteria Kingdom• “ancient” bacteria• Have lived on Earth longer than any other
organism• Live under conditions that would kill other living
things• Can live where there is no oxygen and in areas
where there is extreme heat
Eubacteria Kingdom• Most bacteria fall into this kingdom• Get food in a variety of ways (Some use energy
from the sun & others get food from eating living and non-living things)
Plant Kingdom• Multi-celled organisms with tissues and organs• Cells have cell walls & chloroplasts• Plant cells make their own food• Need water to survive• Scientists classify plants into two main phylum
(groups): vascular & nonvascular
Vascular Plants• Have tissues that act like tubes • These tube-like structures transport water and
nutrients from the soil • Vascular plants do NOT have to live near water• Vascular plants can grow very tall• Example: Fern (Ferns reproduce through spores.)
Nonvascular Plants• Absorb water• Water is passed slowly from cell to cell• Do NOT have tissues to transport water & must
live close to a water source • Do not grow very tall; many reach only a few
inches tall• Example: Moss
