BSC 1010 Exam 2 Questions with 100% Verified Correct Answers Reason for small cell size - Correct Answer To maximize the ratio of surface area to volume cell (plasma) membrane - Correct Answer phospholipid bilayer that protects and encloses the cell; controls transport; maintains homeostasis Cell Wall - Correct Answer outside of cell membrane in some organisms, composed of carbs or carb derivatives Cytoplasm - Correct Answer Material outside the nucleus that is the site for metabolic activity, cytosol, organelles Cytoplasm - Correct Answer Solution with dissolved substance such as glucose , CO2, O2, etc.Cytoskeleton - Correct Answer Supportive and metabolic structure composed of microtubules, microfilaments, and intermediate filaments.Prokaryotic Cells - Correct Answer Simple cellular organization with no nucleus or other membrane- bound organelles. Singular DNA loop Eukaryotic Cells - Correct Answer Complex cellular organization; membrane bound organelles, located inside the cell membrane.Nucleus, Nucleolus, RER, SER, golgi apparatus, lysosome, choloroplast, chromoplast, mitochondrion.Nucleus - Correct Answer DNA in the form of chromosones RER - Correct Answer rough endoplasmic reticulum, protein synthesis SER - Correct Answer smooth endoplasmic reticulum, lipid synthesis Golgi apparatus - Correct Answer A system of membranes that modifies and packages proteins for export by the cell 1 / 2
Chloroplast - Correct Answer Site of photosynthesis Mitochondrion - Correct Answer produces ATP Tonicity - Correct Answer the ability of a surrounding solution to cause a cell to gain or lose water Isotonic - Correct Answer when the concentration of two solutions is the same Hypertonic - Correct Answer A cell with a higher concentration of water inside of the cell than out. It pushed water out and shrivels up. Plasmolyzed. Salts attracting water is an example Hypotonic - Correct Answer A cell with lower concentration of water inside of the cell than out. It absorbs water and swells. Lysed in animal cell, turgid in plant cell.Passive Transport - Correct Answer Requires no energy. Diffusion, facilitated diffusion, osmosis, bulk flow.Diffusion - Correct Answer Movement of molecules from an area of higher concentration to an area of lower concentration.facilitated diffusion - Correct Answer A permease or membrane enzyme carries a substance Osmosis - Correct Answer Diffusion of water through a selectively permeable membrane Active Transport - Correct Answer Requires ATP. Membrane pumps, endocytosis, exocytosis.Membrane Pumps - Correct Answer ATP is required; a permease is used to move a substance, usually in the opposite direction of diffusion Endocytosis - Correct Answer A process in which a cell engulfs extracellular material through an inward folding of its plasma membrane.
