nonliving A virus is a submicroscopic obligatory parasitic particle that infects cells in biological organisms. Viruses are non-living particles that can only replicate when an organism reproduces the virulent RNA or DNA.
The cell membrane is semi permeable-meaning some particles can cross the membrane while others may not. It is made up of layers that are both attracted to water-the phosphate bilayers and layers that are hydrophobic (fatty acid layers).Outside of the cell water makes the phosphate layers line up.smosis is the movement of water across the semi permeable cell membrane. The cell membrane has phospholipid bilayers. These layers are made up of glycerol, two fatty acids, and a phosphate. The phosphate part of the cell membrane is attracted to water but the fatty acid part of the membrane is not.
