LSU BIOL 1201 EXAM REVIEW PRACTICE QUESTIONS AND ANSWERS Latest Updates 2024 All of the following are part of a prokaryotic cell except a) an endoplasmic reticulum b) a cell wall c) a plasma membrane d) ribosomes - ANS a) an endoplasmic reticulum The pores in the nuclear envelope provide for the movement of a) proteins into the nucleus b) ribosomal components out of the nucleus c) mRNA out of the nucleus d) all of the above - ANS d) all of the above Which of the following is incorrectly paired with its function? a) peroxisome —contains enzymes that break down H2O2 b) ECM (extracellular matrix) —supports and anchors cells, communicates between inside and outside of the cell c) Lysosome —contains pigments in plant cells d) Golgi apparatus —processes, tags, and ships cellular products - ANS c) lysossome -- contains pigments in plant cells The innermost portion of a mature plant cell wall is the a) primary cell wall b) secondary cell wall c) middle lamella d) plasmodesmata - ANS b) secondary cell wall Of the following, which is probably the most common route for membrane flow in the endomembrane system? a) rough ER --Golgi --lysosomes --nuclear membrane --plasma membrane b) rough ER--transport vesicles --Golgi --vesicles --plasma membrane c) nuclear envelope -- rough ER--Golgi --smooth ER--lysosomes d) rough ER --vesicles --Golgi --smooth ER --plasma membrane - ANS b) rough ER -- transport vesicles --Golgi --vesicles --plasma membrane The volume enclosed by the plasma membrane of plant cells is often much larger than the corresponding volume in animal cells. The most reasonable explanation for this observation is that a) plant cells are capable of having a much higher surface -to-volume rat io than animal cells b) plants have a much more highly convoluted (folded) plasma membrane than animal cells c) plant cells contain a large vacuole that reduces the volume of the cytoplasm d) animal cells are more spherical, while plant cells are elongated - ANS c) plant cells contain a large vacuole that reduces the volume of cytoplasm Large numbers of ribosomes are present in cells that specialize in producing which of the following molecules? a) lipids b) starches c) proteins d) steroids - ANS c) proteins Of the following, which is probably the most common route for membrane flow in the endomembrane system? a) Golgi --Lysosome --ER--plasma membrane b) ER--chloroplasts --mitochondrion -- cell membrane c) Nuclear envelope --Lysosome -- Golgi --plasma membrane d) rough ER -- vesicles -- Golgi -- plasma membrane - ANS d) rough ER --vesicles -- Golgi --plasma membrane Which of the following are capable of converting light energy into chemical energy? a) chloroplasts b) mitochondria c) Golgi bodies d) lysosomes - ANS a) chloroplasts Which of the following pairs is mis-matched?
