Main Focus Points for Studying

-What is a cell?

-Characteristics an organism must have to be -considered alive

-Basic virus anatomy, bacteriophage anatomy and life cycle

-(Basics) Contributions of Robert Hooke and Anton Van Leeuwenhoek

-Prokaryotes vs. Eukaryotes

-Anatomy and functions of the nucleus

-DNA packaging

-Organelles- cytoplasm-->mitochondria

-Why is mitochondria special!

-Structure and function of plasma membrane

-Membrane transport- simple diffusion, passive vs active transport, endocytosis, exocytosis, phagocytosis, pinocytosis
