CHAPTER 4 CELLS AND FUNCTIONS Flashcards
STORES food, water and waste
VACUOLE
BREAKS DOWN big food MOLECULES.
LYSOSOME
supplies ENERGY
MITOCHONDRIA
PACKAGE and MOVE PROTEINS
GOLGI APPARATUS
SUPPORTS, PROTECTS ORGANELLES
CYTOPLASM
SEPARATES CHROMOSOMES during MITOSIS
CENTRIOLES
MAKES PROTEINS
RIBOSOME
MOVES things around cell and MAKES PROTEINS too
(ER) ENDO-PLASMIC RETICULUM
MAKES RIBOSOMES
NUCLEOLUS
CONTROLS THE CELL and ACTIONS (BRAIN)
NUCLEUS
PROTECTION, REGULATES what goes IN and OUT (SKIN)
CELL MEMBRANE
does NOT have RIBOSOMES
SMOOTH ER
HAS RIBOSOMES
ROUGH ER
ISOTONIC solution
NORMAL CELLS remain UNCHANGED
HYPOTONIC solution
cell SWELL and BURST
HYPER-TONIC solution
cell shrivel
water to MOVE OUT of the cell
HYPERTONIC
greater CONCENTRATION
HYPERTONIC
water to MOVE INTO the cell
HYPOTONIC
lower CONCENTRATION
HYPOTONIC
DIFFUSION of water across the PLASMA MEMBRANE
OSMOSIS
substance is HELPED across the PLASMA MEMBRANE by a molecule WITHIN membrane
FACILITATED DIFFUSION
MOVEMENT of water and DISSOLVED substance
FILTERATION
back INTO the cell
ENDOCYTOSIS
REMOVES waste OUT of the cell
EXOCYTOSIS
DIFFUSION of water ACROSS the plasma membrane
OSMOSIS
sodium/potassium MOVES ions IN and OUT of the cell
ACTIVE TRANSPORT PUMP
NO energy required, moves MOLECULES from AREA of HIGH CONCENTRATION to LOW CONCENTRATION
PASSIVE TRANSPORT
REQUIRES energy, moves MOLECULES from AREA of LOW CONCENTRATION to HIGH CONCENTRATION
ACTIVE TRANSPORT
water ENTER the CELL to EXPAND
HYPOTONIC
water will SHRINK the cell
HYPERTONIC
process of moving IONS across the CELL MEMBRANE.
ACTIVE TRANSPORT PROCESS
SODIUM-POTASSIUM PUMP
moves molecules back INTO a cell
ENDOCYTOSIS
moves molecules OUT of a cell
EXOCYTOSIS
moves MOLECULES from LOWER concentration INTO HIGH CONCENTRATION
OSMOSIS
NUCLEIC acid along with proteins and carbohydrates
RNA and DNA
