The advantages of the closed-cell foam compared to open-cell foam include its strength, higher R-value, and greater resistance to the leakage of air or water vapor. The disadvantage of the closed-cell foam is that it is more dense, requiring more material, and therefore, more expense.
Plant cells are somewhat unique because unlike animal cells, plant cells contain both a cell wall and cell membrane. Animal cells only have the cell membrane. The cell membrane is a semi-permeable covering surrounding the outside of the cell. Plant cell membranes are found on the outside of the cell cytoplasm and just inside the cell wall. So, the answer to the question, 'Do plant cells have a cell membrane?', is 'Yes!'.
