10. Diffusion Definition: When molecules move from an area of high concentration to low concentration. (used to move materials inside of cells)

11. Osmosis Definition: When water moves through a selectively permeable membrane.

12. Permeable 3 types Permeable: Lets things pass through Impermeable: Does not let things pass through Selectively Permeable: Lets some things pass through

13. Turgor Pressure Definition: The pressure on pushing on the cell wall from the inside of the cell. Water enters the cell by osmosis this causes the vacuole and cytoplasm to swell and push against the cell wall.

14. Cell Organisation Tissue: Group of cells with similar structure and function – Epithelium (skin) Organ: Tissue that has formed into a larger structure. May contain more than one type of tissue. Each organ has at least one function. – Lungs, heart, bone Organ systems: groups of organs with a related function. – Stomach + intestine + esophagus + liver =Digestive system

19. Protists Definition: single celled organisms from the kingdom protista (not plants, animals or fungi) 2 types of protist: Plant like protists: Although they are NOT PLANTS they still use chlorophyll to make their own food like plants do. – Examples: Diatoms, Algae Animal like protists: Must get their food from other living things (may be living or dead food) – Examples: amoebas, Paramecium

20. How Do Amoebas eat? Definition: An amoeba is a blob like single cell organism. It moves by stretching out “legs” called pseudopods and pulling itself along. How do they eat:

21. How Do Amoebas eat? Definition: An amoeba is a blob like single cell organism. It moves by stretching out “legs” called pseudopods and pulling itself along. How do they eat: It wraps itself around the food using pseudopods and closes in around it. Once it has covered its prey it creates a food vacuole with the prey inside it
