It is not depenent on a concentration gradient.
Cells get energy from the food you eat. In particular, cells get energy from ATP which is product of cellular respiration in many organisms and photosynthesis in plants. When ATP is cleaved and leaves a phosphate (Pi) and ADP this reaction releases a great amount of energy, which can then be used by the cell.
No, bacteria do not have mouths like animals do. Instead, they absorb nutrients through their cell wall or membrane. Bacteria use various methods to obtain nutrients, such as secreting enzymes to break down molecules in their environment and then absorbing the smaller components.
low growing, doesn't have great roots for absorption, like damp, shady places, lack well developed transport tubes
With the exception of walking, cycling is the cheapest means of transport.
[Molecules pass through the cell membrane] through a process known as osmosis. ------------------------------------------------------- Yes, osmosis is a great part of diffusion of molecules, but another important factor to consider is the presence of protein channels in the membrane. The cell membrane is actually a lipid bilayer, in which proteins are embedded. Normally, molecules will simply be diffused through these chanells, but in some cases, the protein must be modified in order to allow the molecules to flow. This is called active transport, which requires energy in order to change the shape of the protein and allow the foreign molecule to pass.
The ability to transport goods has always proved to be a great advantage. England and the Vikings used the water. Railroads provide the same advantage, 1 driver can drive tons of goods, food, weapons, etc. This provides a great advantage over wagons and what not where 1 person can't take much more than what they need let alone providing for others.
