1. Cells

2. • Domains: Archaea and Eubacteria
Prokaryotes
Prokaryotes: no nucleus or organelles
• Domains: Archaea and Eubacteria

3. Eukaryotes Eukaryotes: nucleus and organelles
Organelle: structure in cells that perform specific functions
Plasma membrane: outer boundary of cell
Cytoplasm: portion of the cell outside the nucleus
Nucleus: cell control center; contains DNA

5. Organelles Ribosomes: create proteins from RNA
Endoplasmic reticulum: produces, transports, and stores enzymes/proteins

7. Organelles
Golgi apparatus: sorts, packages, and secretes proteins and lipids
Lysosomes: digest organic molecules

9. Organelles
Mitochondria: convert energy to ATP; have their own DNA that is passed from mother to offspring
Cilia/flagella: help the cell move
Vacuole: membrane sac

11. Nucleus
Nucleus: contains DNA; control and information center for the cell
Nuclear envelope: membrane that separates nucleus from cytoplasm
Chromatin: DNA and protein
Chromosomes: DNA, made of tightly coiled chromatin

13. Parts to the Chromosome
Centromere- is the part of a chromosome that links sister chromatids.
Chromatid-contains DNA
