4 Structure & Function Fluid Mosaic Model of the Cell Membrane Phospholipid bi-layer Proteins Carbohydrate chains

5 Selective Permeable Membrane Membrane that allows some materials, but not all to cross.

6 Materials Cross in Different Ways: Passive Transport Active Transport Endocytosis Transport Exocytosis Transport

7 Without Using Energy Passive Transport Diffusion Osmosis Facilitated Diffusion

8 Diffusion (Passive Transport) Movement of molecules from a place of higher concentration to a place of lower concentration

9 Osmosis (Passive Transport) Diffusion of water molecules from an area of higher concentration to an area of lower concentration.

10 Facilitated Transport (Passive Transport) Transport proteins make it easier for materials to pass through the membrane.

11 State of Equilibrium Diffusion or Osmosis continues until a state of equilibrium is reached.

12 Effects of Osmosis Osmosis affects cells in various ways. When Cells are Placed In Solutions: Hypertonic Isotonic Hypotonic Solution Solution Solution

13 Using Energy Active Transport Exocytosis Endocytosis - sometimes this ends in phagocytoses which means “cell eating”

14 Active Transport When cells need materials that can not cross the membrane they can use energy to drive them through transport proteins.

15 Exocytosis Large materials that can not cross the cell membrane EXIT the cell in a vesicle.

16 Endocytosis Large materials that can not cross the cell membrane ENTER the cell in a vesicle.

17 Endocytosis Large materials that can not cross the cell membrane ENTER the cell in a vesicle. X

29 Nucleus Contains the cell’s DNA and is the control center of the cell.

30 Ribosome Assembles amino acids into proteins.

31 Endoplasmic Reticulum Surrounds nucleus. Sometimes studded with ribosomes, sometimes smooth. Functions vary according to cell type.

32 Endoplasmic Reticulum Sometimes packages proteins and sends them out of the cell. Sometimes sends them to the Golgi complex for further packaging and transport.

33 Endoplasmic Reticulum Makes lipids and sends them to the Golgi Complex for transport.

34 Golgi Complex Transports proteins and other materials out of the cell in vesicles.

35 Mitochondrion Breaks down food molecules to make ATP

36 Lysosome Digests food particles, wastes, cell parts and foreign invaders

37 Chloroplast Uses the energy of sunlight to make food

38 Large Central Vacuole Stores water and other materials

39 Cell Wall Surrounds the cell membrane in plants and provides structure

40 Cilia Moves liquid across a cell

41 Flagellum Provides movement, also a sensory structure

42 Cytoskeleton Provides structure. Made up of microtubules and filaments that help cells maintain their shape

43 Cytoplasm Jelly-like fluid that fills the cell and suspends the organelles.
