they do everything for your body
Simple diffusion and osmosis help maintain homeostasis in cells and do not require the cell to expend energy.
depends on your definition of activity and what scope you are looking at things, but yes, there is energy put into the process at some point. just remember that diffusion and other similar phenomenon don't require energy usage on the part of the organism
All life actives take place in cells #one answer
Plants need energy because they are living things. Living things require energy to carry out a number of processes, including growth and reproduction.
The urine and saliva
All of your cells require energy. Without energy you wouldn't be alive.

All living organisms (not dead) require energy
All cells require ATP for energy
Galvanic cells run spontaneously and do not require any energy to run to completion, but Electrolytic cells require energy to run to completion, and are non-spontaneous.
Cells that require a lot of energy for daily activities, such as muscle cells.

All living things require a source of energy.
Cells that require a lot of energy to carry out their functions, such as muscle cells and nerve cells, tend to have a high concentration of mitochondria. Muscle cells, for example, require a lot of energy to contract and relax, so they have a high density of mitochondria to produce the ATP (adenosine triphosphate) required for energy. Similarly, nerve cells require a lot of energy to transmit signals along their length, so they also have a high concentration of mitochondria. Other cells that have a high density of mitochondria include liver cells, which have a lot of metabolic processes, and kidney cells, which require a lot of energy to carry out their filtration function.
