Why are scientific names written in Latin?
It is the easiest language to learn
Latin is used so scientists everywhere can understand
Latin names are shorter than English names
Latin is used only for insects
A dichotomous key helps scientists:
Name planets
Identify organisms based on traits
Measure chemical reactions
Write scientific names
The word 'dichotomous' means:
Put in order
Mixed together
Cut in two
Extremely large
A dichotomous key uses:
Learned behavior
Inherited traits only
Colors of the organism
The organism’s diet

Protists are eukaryotic, meaning they:
Have no nucleus
Have a nucleus enclosed in a membrane
Have no cell parts
Are prokaryotes
Protists similar to plants can:
Produce toxins
Perform photosynthesis
Infect bacteria
Absorb food like fungi
How are fungi different from plants?
Fungi are always multicellular
Fungi perform photosynthesis
Fungi absorb nutrients instead of making food
Fungi live only in water
Mushrooms, molds, and yeast belong to:
Protista
Plantae
Animalia
Fungi
Fungi are important in ecosystems because:
They make oxygen
They break down organic matter
They control animal populations
They remove salt from water
Plants are primary producers because they:
Eat insects
Absorb nutrients from soil only
Make their own food using photosynthesis
Produce fungi

Angiosperms
Flowering plants
Ferns and mosses
Fruit trees
Plants support life by:
Producing oxygen
Eating bacteria
Releasing toxins
Absorbing sunlight only at night
Animals are:
Autotrophs
Eukaryotic heterotrophs
Prokaryotes
Capable of photosynthesis
Animals depend on plants because:
Plants clean their fur
Plants provide oxygen and nutrients
Plants reproduce animals
Plants control behavior
