| Question | Answer |
|---|---|
| "living matter" | cytomplasm |
| surrounds and serves as a boundary for cells | plasma membrane |
| component of plasma membrane | cholesterol |
| controls preprodcution of th cell | nuclues |
| function in cell reporduction | centrioles |
| power plug | mitochondria |
| digestive bug | lysosomes |
| chemical processing and packaging center | golgi apparatrus |
| protein factories | ribosomes |
| smoot and rough | endoplasmic reticulum |
| energy reuired for active trasport is obtained from what? | atp |
| example of passive transport | diffusion |
| movement of substances from a region of high concentration to a region of low concentration | passive transport |
| involves the movement of solutes across a selectively permeable membrane by diffusion | osmosis |
| specialized example of diffusion | osmosis |
| always occurs down a hydrostatic pressure gradient | filtration |
| uphill movemnt of a substance through a living membrane | active transport proceess |
| example of active transport process | ion pump, phagocytosis, and pinocytosis |
| example ofa cell that uses phagocytosis is the | white blood cell |
| solution that contrains a higher concentration of salt than livig red blood cells | hypertonic |
| when a red blood cell becomes engorged with water and will eventually lyse | hypotomic |
| internal living material of cells is | cytomplasm |
| protein factoris | ribosomes |
| process of enzymes using oxygen to break down glucose and other nutrients to release energy required for cellurlar qork is | cellular respiration |
| two of these rod-shaped structures exist in every cell | centrioles |
| adenosine triphospphate is the chemimcal substance that provides the energy required fr | active transport |
| a solution that contains a lower concentration of salt thatn living red blood cells would be | hypotomic |
| it is the sequence of base paires in each gene of each chromosome that deetermines | heredity |
| specific and visible stages of cell divion are precided by a period called | interphase |
| stratified squamos epithelium assiste the body how? | protection against invasion by micropgranisms |
