All living things need to get energy. living things can be autotrophs or heterotrophs.
Cells form their own organic compounds through the use of energy resulting in cell control and growth.
Energy is released when organic compounds split causing chemical bounds to break.
Cell activity produces soluble waste products.
External stimuli change a cell's activity causing a cellular response.
non-waste molecules made by cells are released to influence extra cellular activity. An example is a hormone.
The cell position can be changed by an energy release in the cell.
Cell division causes an increase in cell number.
food is broken down, with the help of enzymes, into smaller, soluble pieces for cells to use.
Food molecules, water, ions and other necessary items are transported from the enviroment into the cell.
insoluble, non-digested waste products that could not be used or broken down by the cell.
