CELLULAR FUNCTIONSCell Wall
gives the cell structure and support
Plasma (Cell) Membranemaintains homeostasis within the cell by
allowing some substances to enter and others to leave
Vacuolesstores water and some nutrients as well as maintains turgor pressure within plant
cells; in animal cells it is used to store waste products and to transport proteins
packaged by the Golgi body.

CELLULAR FUNCTIONS
Nucleus

CELLULAR FUNCTIONSDNA (genetic material)
used by the cells for movement
Cilia/Flagella
fluid part of the cell that suspends organelles and where most metabolic activity takes place
Cytoplasm
produces materials for the cell and transports them to the Golgi body; rough is an attachment point for
ribosomes
Endoplasmic Reticulum smooth & rough
contains the genetic code for making proteins

What are three main differences between prokaryotic and eukaryotic cells?
*prokaryotic cells are small, eukaryotic cells are bigger

DEFINE THE FOLLOWING TERMS, DESCRIBE THE MOVEMENT OF WATER AND WHAT HAPPENS TO THE CELL:
Isotonic SolutionDefine: equal movement of water in/out of the cell Water movement: both in and out What happens to the cell?: stays the same
Hypotonic SolutionDefine: a hypotonic solution refers to a solution that contains less solute (more water) compared to the cytoplasm of the cell Water movement: water moves into the cell What happens to the cell?:Cell swells
Hypertonic SolutionDefine: A solution that has higher osmotic pressure (or has more solutes) than another solution to which it is compared Water movement: water moves out of the cell What happens to the cell?:Cell shrivels

EXPLAIN THE DIFFERENCE BETWEEN PASSIVE AND ACTIVE TRANSPORT.
Passive transport does not require energy.
Active transport requires energy.

DEFINE EACH OF THE FOLLOWING TYPES OF TRANSPORT AND INDICATE WHETHER IT IS PASSIVE OR ACTIVE.
simple diffusion: small molecules moving across the cell membrane from high to low concentrations: passive facilitated diffusion: large molecules using a protein channel to move across the cell membrane from high to low concentrations: passive
endocytosis: A process in which cell takes in materials from the outside by engulfing and fusing them with its plasma membrane, active
