Answer:
Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.
The new substances that are formed during a chemical reaction are called the products. The original substances are called the reactants. For example, when hydrogen gas is added to oxygen gas and ignited, the new substance water is formed. The reactants are hydrogen and oxygen.

The cell membrane maintains homoeostasis in the body which is the process by which cell maintains a fairly constant environment.
<h3>What is the cell membrane?</h3>
The cell membrane is a lipid bilayer membrane which separates the contents of a cell from the external environment.
The correct graphical chart is as follows:
- cell membrane maintains homeostasis
- active transport requires energy
- passive transport does not require energy
- Diffusion occurs either through osmosis or facilitated diffusion
- facilitated diffusion occurs through protein channels
- Osmosis involves movement of water
- Endocytosis is the process the cell takes in substances into its inner compartment
- Exocytosis is the process the cell takes in substances into its inner compartment
- Pinocytosis is cell drinking
- Phagocytosis is cell eating
Therefore, the process by which cell maintains a fairly constant environment is called homoeostasis and is maintained by the cell membrane.
