Describe unicellular organisms. they are made of one cell; they are simple; the cells do not have specific jobs
Describe multicellular organisms. they are made of two or more cells; they are more complex; they have cells with specific functions
Describe sexual reproduction. 2 parents; the offspring is a combination of the two parent cells
Describe asexual reproduction. 1 parent; the offspring is identical to one parent
What is the function of water as a chemical of life? the most common chemical; essential for life
What is the function of carbohydrates as a chemical of life? they provide cells with energy

Name the 4 needs of all living things. water; food; space; homeostasis
Describe water as a NEED for all living things. cells need it; substances dissolve in water and are transported easily
Describe food as a NEED for all living things. (autotrophs; heterotrophs) autotroph- self feeder (producer) heterotroph- feeds on others (consumer; decomposer)
Describe space as a NEED for all living things. must have food and water in living space; competition for survival exists in this space

Describe organisms in the Domain Archaea. they are microscopic; they have no nuclei; they often live in harsh environments
Describe organisms in the Domain Bacteria. they are microscopic; they have no nuclei; they are found all around us
Describe organisms in the Domain Eukarya. they have a nuclei; they are usually multicellular
