1. Classification (background knowledge)
Many of these word you should already know

2. Terms to Remember for this Unit:
Classification: The grouping of organisms based on thier
similarities OR differences
Taxonomy: The study of Classifications
(these scientists are called taxonomist)
Unicellular: Any one celled organism
Multicellular: having many (more than one) cells
Autotrophic: (Producers): makes it own food internally through photosynthesis
Heterotrophic: (Consumers) must ingest food from
the environment

3. Eukaryotes: cells with Nucleus, Endoplasmic Reticulum, golgi bodies, mitochondria, chloroplasts
Prokaryotes: cells with no membrane bound organelles just DNA, RNA, ribosomes, cell wall/membrane
Sexual Reproduction: genetic information DNA is exchanged to make new genetically distinct individual - needs two parents
Asexual Reproduction: DNA is simply replicated and a the “offspring “ is a genetic clone of the parent- only one parent needed

4. The grouping of organisms based on their similarities
