This energy comes from the molecule ATP,which stores energy in a form that cells can use

Water is useful to plants because cells need water to transport nutrients around the cell.
active transport by endocytosis
We need nutrients and oxygen to be supplied to our cells at a very fast rate as our cells need a lot of energy to keep us alive. Therefore we must have an efficient transport system to transport nutrients and oxygen to the billions of cells in our body. The transport system in man is known as the circulatory system.
Cells do not gain energy through facilitated diffusion. Facilitated diffusion is a passive process in which molecules move across the cell membrane from an area of higher concentration to lower concentration with the help of transport proteins, without the need for energy input. Cells use energy through other processes such as active transport and cellular respiration to maintain their functions.
Cells use active transport to move substances against their concentration gradient or across a membrane with the help of energy from ATP. This process is necessary for the cell to maintain proper internal conditions, such as ion balance and nutrient uptake, which are essential for its survival and functioning.
Facilated transport does not need to use energy but active transport does.
