Our life depends on the smallest building blocks of our body, our cells. They are in our muscles, bones, skin, and brain. They are specialized depending on where they are and what they do. Each of them has its own little organs, called organelles. These structures make it possible for the cell to perform its duties.

This is the knowledge we need to understand why leaves are green, why we have oxygen in the atmosphere, and what happens to the carbon dioxide we breath out.

Objectives

When you complete this lesson, you will know that,

• That a semi-permeable membrane covers the cell. This helps them to take in food and energy, and dispose of materials they don't need.
   
• What the organelles are and what do they do.
   
• How the energy system of a cell works.
   
• Why the enzymes are important.  These special proteins help chemical reactions in cells. They never take part in the reaction itself but help the materials to combine.
   
• What the connection is between enzymes and the cell wall.
   
• How a prokaryotic cell, a eukaryotic cell, and a virus functions.
   
• How the information flows from the RNA in the nucleus to the ribosomes.
   
• How this helps the cell to make proteins.
   
• What the role is of the Golgi apparatus and the endoplasmic reticulum. The plant cell uses the energy from the sunlight to make sugar. The mitochondria break down glucose to produce energy.
   
• The different cells and organisms build macromolecules from simple "building blocks".
   
• The mitochondria and the chloroplasts are special molecules that store energy for ATP production.
   
• The cytoskeleton and the cell wall give the cell its shape.
