What is diffusion? | Diffusion is the net passive movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. |
What is osmosis? | Osmosis is the spontaneous net movement of solvent molecules through a semi-permeable membrane into a region of higher solute concentration |

Describe the process of breathing. | Air is brought in through the nose, then goes down the trachea into the bronchial tubes. The oxygen passes to the bronchioles to the alveoli to the capillaries and the oxygen is transported through the blood stream by the cardiovascular system. |

What is the function of the nucleus? | contains the hereditary material DNA and directs the activities of the cell. |
What is the function of the cell membrane? | forms the outer covering of the cell, and is semi-permeable. |
What is the function of cytoplasm? | is a gel-like matrix where all the other cell organelles are suspended inside the cell. |
What is the function of Goli Complex? | is responsible for storing, packaging of cellular products. |
What is the function of lysosomes? | are enzyme sacs, that digest cellular wastes. |
What is the function of the Mitochondria? | is the site for cellular respiration and producers of energy. |
What is the function of the Ribosomes? | are made of RNA and proteins, and are sites for protein synthesis. |
What is the function of the nucleolus? | is the structure within the nucleus and helps in synthesis of ribosomes. |
