unicellular= made up of one cell
multicellular= made up of multiple cells
homeostasis= balance
reproduction= producing more new organisms
DNA= large molecule that contains genetic information
gene= a short segment of DNA that contains information for your traits

autotrophs= produce their own food; plants
heterotrophs= eat food produced by autotrophs
Characteristics of living things:
1. cells= made up of cells
2. highly organized at both the molecular and cellular levels
3. energy (metabolism)
4. homeostasis= maintain stable conditions inside the body
5. grow
*cell division (mitosis)
*formation of 2 new cells from one cell
*development -> child -> adult
6. reproduction= form new organisms
