Cells are the basic unit of all life forms. Cells interact with their environments in different ways - gaining from the environment and also modifying the environment.
As a cell goes through its life cycle, it will need to gain nutrients from the environment that support its cellular activity and aid it to grow. The process by which a cell gains nutrients from the environment are numerous and are as follows:
1) Osmosis: this is a process by which molecules move from into the cell through its cell membrane from less concentrated solutions around it.
2) Phagocytosis - process by which certain living cells called phagocytes, such as amoeba and white blood cells ingest or engulf other cells particles.
3) Diffusion - diffusion is a the by which molecules move into a cell from a more concentration to its less concentrated solution.
4) Active Transport - is the movement of molecules across a cell membrane from a region of their lower concentration to a region of their higher concentration—in the direction against some gradient, through use of energy.
The cell can also modify its environment through the same processes. Cells use up the nutrients obtained from their environment in many processes and eventually excrete them back to their environment.
This in turn leads can lead to accumulation of some of these excretions, which some can be toxic. Consequently this leads to a modified environment in terms of the components,
