... cell membranes; water, nutrients, wastes can be found in this space. 3. Each membrane appears as a light layer sandwiched between two darker layers because of the phospholipids bilayer structure. The nonpolar (hydrophobic) tails will be inside which is the light layer, and the polar (hydrophilic) head will be outside which is the darker layers. 4. The role of a cytoskeleton in a living cell is to supply structure to the cell, give the cell the ... the Golgi apparatus whether they belong inside the cell in some membrane-bound organelle or in a secretory vesicle. 16. 1) Break-down 'digestio...

... support for the interior of the cell, the cytoskeleton is involved in intracellular organelle transport. Since there are no organelles to be transported in prokaryotic cells, this function is unnecessary. This would suggest prokaryotes as the more primitive cell. Prokaryotic cells contain a single compartment enclosed within the cell membrane. There are no chromosomes and so the circular DNA is found free in the cytoplasm. In contrast, in eukaryotes, the DNA is located on the chromosomes, and is contained within the nucleus. This ... again would suggest prokaryotic cells as the ... ...
