b- cell wall

pg. 13 Q23 The rough ER is a cell structure that consists of folded membranes that contain ribosomes what is the advantage of the folded membranes a- increases surface area in order to produce more proteins b- decreases surface area in order to produce more proteins c- increases volume of the ER in order to produce more energy d- decreases volume of the ER in order to make more energy

b- decreases surface area in order to produce more proteins

pg. 10 Q15 Cells found in plants and animals have similarities but can differ in function. consider the following two organisms: a corn plant cell (Zea mays) and a camel cell (Bactrianus ferus) What is the best explanation for the difference in the cellular vacuole size between these two biotic organisms a- the corn cells' have a small vacuole size because it does not need long term water and electrolyte storage b- the camel cells' have a small vacuole size because it does not need long term water and electrolyte storage c- the camel cells' have a small vacuole size because it is not contact with toxins that need to be removed from the cell d- the corn cells' have a large vacuole because it is in contact with many toxins in the soil which need to be removed from the cell

b- the camel cells' have a small vacuole size because it does not need long term water and electrolyte because storage

pg. 10 Q14 Muscle cells are responsible for obtaining energy so the body can perform voluntary and involuntary movement. Using your knowledge about organelles and muscles, how would a muscle cell differ from other types of animals cells? a- the muscle cells would have larger centrioles than the other types of animals cells b- the muscle cell would have more mitochondria than the other types of animals cells c- the muscle cell would have a larger golgi apparatus than other types of animals cell d- the muscle cell would have more endoplasmic recticulum than the other types of animals cells

b- the muscle cell would have more mitochondria than the other types of animals cells

pg.11 Q16 Cells can be classified into two different categories: prokaryotic and eukaryotic . Which of the following information is needed in order to determine if an organism is prokaryotic a- the organism's color and mass b- the organism's internal structures c- if the organism is unicellular or multicellular d- the methods the organism uses to feed and move

b- the organsim's internal structures

pg. 11 Q19 Which of the following contain complex, membrane- bound organelles 1- bacteria 2- viruses 3- eukaryotic 4- prokaryotic a > 1 & 2 b > 2 & 4 c > 3 only d > 4 only

c > 3 (eukaryotic) only

pg. 14 Q27 Which of the following functions does active transport perform in a cell a- packaging proteins for export from the cell b- distributing enzymes throughout the cytoplasm c- moving substances against a concentration gradient d- equalizing the concentration of water inside and outside the cell

c- moving substances against a concentration gradient

pg. 12 Q22 What is the advantage of cells being so small a- small cells contain a greater quantity of enzymes than large cells b- small cells do not require energy and get everything they need from osmosis c- the cell has a smaller surface area to volume ration which means it can move nutrients into the cell and waste out more efficiently d- the cell then has a larger surface area to volume ratio which means it can move nutrients into the cell and waste out more efficiently

c- the cell has a smaller surface area to volume ration which means it can move nutrients into the cell and waste out more efficiently
