2. Reproduction

3. The cells of all organisms contain a molecule called deoxyribonucleic acid (DNA). controls all cell activities. holds all the genetic information to carry on all life activities. is passed on to offspring when organisms reproduce. (offspring is a new organism produced by one or more parents)

4. Organisms make other organisms like themselves through the process of reproduction. Two Main Types: Asexual Reproduction Sexual Reproduction

5. when a single parent produces offspring that are the same as the parent Microorganisms are single-celled organisms that reproduce through asexual reproduction Asexual Reproduction

6. Euglena Single-celled organisms Asexual reproduction Flagella (whip like thread that propel the euglena through water)

7. Amoeba Single-celled organisms Asexual reproduction Pseudopodia false feet are extensions of the amoebas body, used for movement and eating.

8. Paramecium Single-celled organisms Asexual reproduction Cilia (hair like structures that beat back and forth to move it forward)

9. Bacteria round shape Staphylococcus aureus (skin infection) rod shape Salmonella (food poisoning) Single-celled organisms Asexual reproduction spiral shape Lyme disease (tick bites) Three Types

10. Is when two parents produce offspring that share characteristics of both parents. Most multi-cellular organisms reproduce through sexual reproduction. Sexual Reproduction Sperm Cell – male gamete Egg Cell – female gamete (the largest cell in the human body).

11. One parent Offspring identical to parent Many offspring Takes place in single- celled organisms Example: Paramecium Two parents Offspring have characteristics of both parents (diverse- different) Few offspring Takes place in multi- celled organisms Example: Cats
