Many of these organisms were also treated as fungi due to a similar environmental role: that of a decomposer.

This may sound a bit strange question, but I am very new to biology. I would like to ask that do microorganisms like viruses, bacteria, amoebas, etc also contain water, as every living thing contains
Ions cannot diffuse passively through membranes; instead, their concentrations are regulated by facilitated diffusion and active transport.Learning ObjectivesExplain the relationship between osmotic pressure and the transport of electrolytes across cell membranesKey PointsImportant ions cannot pass through membranes by passive diffusion; if they could, maintaining specific concentrations of ions would be impossible.
