2. 2.What is a Prokaryotic Prokaryotic have few internal structures One-celled organisms, like Bacteria

3. 3. What is Eukaryotic Contain organelles surrounded by membranes Most living organisms like plants animals, fungi

4. 4. What are elements? An element is any substance that cannot be broken down into simpler substances. Examples of elements are oxygen and nitrogen.

5. 5. Name the elements found in living things The element found in living things are carbon, hydrogen oxygen, nitrogen and phsophrous

6. 6. What are compounds? Are when two or more element combine chemically they form a compound. For example carbon and oxygen Water is also a compound because it is made up of hydrogen and oxygen.

7. 7. What are carbohydrates? Carbohydrates is an energy rich compound made of the elements carbon, hydrogen and oxygen. Sugars and starches are examples of carbohydrates.

8. 8. What are lipids? Lipids are energy rich organic compounds made of carbon, hydrogen, and oxygen. Lipids contains more energy than carbohydrates.

9. 9. What are proteins? Proteins are large organic molecules made of carbon, hydrogen, oxygen, nitrogen and in some cases sulfur. Protein are also made up of smaller molecules called amino acids There are 20 different amino acids

10. 10. Describe the function of protein Most structure of cells are made up of proteins like the cell membrane and the organelles. Proteins are also known as enzymes which performs important functions in the chemical reactions that takes place in cells.

11. 11. What is nucleic acids Nucleic acids are very long organic molecules made up of carbon hydrogen, nitrogen and phosphorus. Nucleic acid contains the instructions that cells need to carry out all the functions of life There are two kinds of nucleic acids DNA and RNA.

12. 12. What is DNA and RNA DNA is deoxyribonucleic acid contains the genetic material that carries information about and organism RNA is Ribonucleic acid helps in the production of proteins and it is found in the cytoplasm and the nucleus.
