SECTION VI
41) When red blood corpuscles (animal cells without a cell wall) are placed in distilled water, water moves into the cells by osmosis due to a higher water potential outside. This causes the cells to swell and burst (hemolysis), leaving only fragments.
42) The transport of soluble products of photosynthesis (sugars) from the leaves to other parts of the plant, including storage organs, is called translocation. This process occurs in the phloem.
