Answer:The cell membrane functions as a barrier that makes it possible for the cytoplasm to maintain a different composition from the material surrounding the cell. The unit membrane is freely permeable to water molecules but very impermeable to ions and charged molecules. It is permeable to small molecules in inverse proportion to their size but in direct proportion to their lipid solubility.
Amylose is less soluble in water. It does not form a gel when hot water is added. Amylose constitutes about 20-30% of the starch. Amylose can be hydrolyzed with α amylase and β amylase enzymes completely.
