1. In & Out of Cells (The Cell In Its Environment) Passive TransportActive Transport

2. Almost all living things get energy from light. Directly: plants Indirectly: animals Photosynthesis “to make with light”

3. CO 2 + H 2 OC 6 H 12 O 6 + O 2 carbon dioxide + waterglucose (sugar) + oxygen chloroplast capture energy from sunlight water enters through roots and moves to leaf carbon dioxide enters through stomata

4. + 6CO 2 6H 2 O C 6 H 12 O 6 6O 2 as sunlight flour, sugar, eggs glucose & oxygen cake carbon dioxide & water oven as photosynthesis baking a cake raw materials products

5. Photosynthesis Capturing Sun’s EnergyUsing Energy to Make Food chlorophyll (pigment) in chloroplast absorbs light water is absorbed by roots and travels to leaves carbon dioxide enters leaf through stomata chemical reactions occur to produce sugar and oxygen

6. Cellular Respiration Eat Breakdown molecules Digest Absorb molecules Glucose Cell Mitochondrion

7. C 6 H 12 O 6 + O 2 CO 2 + H 2 O + energy glucose + oxygencarbon dioxide + water + energy Fermentation: energy is released without oxygen.

8. Cell Division Interphase Mitosis cell grows cytoplasm divides organelles are distributed animal cells: cell membrane squeezes together plant cell: cell plate forms in middle Cytokinesis DNA is copied preparation for division ProphaseMetaphaseTelophaseAnaphase chromosomes form centrioles move/spindle fibers form nuclear envelope breaks down chromosomes line up in middle chromosomes attach to spindle fiber chromosomes split into chromatids become new chromosome chromosomes move to opposite ends chromosomes stretch out nuclear envelope forms
