Question
Consider two membranes, Membrane A and Membrane B. Membrane A is more fluid compared to membrane B. This may be because: A) Membrane A has longer phospholipid tails, thus lowering hydrophobic interactions to increase membrane fluidity. B) Membrane B has more cholesterol, thereby increasing membrane fluidity due to the increase of hydrophobic interactions. C) Membrane B has more unsaturated phospholipids, thus increasing the hydrophobic interactions between the tails and decreasing its fluidity. D) Membrane A has less integral proteins than Membrane B. (E))You would expect none of the above Ions can travel directly from the cytoplasm of one plant cell to the cytoplasm of an adjacent cell through: A) desmosomes. B) plasmodesmata. C) gap junctions D) intermediate filaments E) tight junctions.Explanation / Answer
20. None of the above ans is correct because if membrane fluidity is more for membrane A then it should consists of short length of fatty acid chain, more unsaturated fatty acids, more cholesterol and more integral proteins as compared to membrane B.
21. Ions can travel directly from the cytoplasm of one plant cell to the cytoplasm of adjacent cell through plasmodesmata. Plasmodesmata is the intercellular channel through which is responsible for the movement of molecules through symplastic pathway.
