2.  Step 1  Convert ________ energy in to ___________ ______ energy  Ends in ___________  Step 2  Convert _________ food energy into energy that the cell can use  Ends in ______

3.  Plants do step 1 with _______________  Plants do step 2 with _______________  Because plants make their own food and then eat it, they are called ____________

4.  Only do step 2 with ______________  Because animals must eat food that others have made, they are called _________________.

6.  Convert _________ energy into _________  ___________ performs photosynthesis  Plants, algae, some bacteria, and some protists all perform photosynthesis  Overall reaction:  6________ + 6______ → ___________ + 6______

7.  Found only in ______ cells  _________: coin-shape structure containing ____________ and ___________; also called photosystems  __________- stacks of thylakoids  _________- fluid inside chloroplast (similar to __________)

8.  Water  Water ____________ can slow or stop photosynthesis  Plants in dry climates  _______ coating  _______ leaves (needles on cactus)  Temperature  ______ temps slow or stop photosynthesis  ___________ do not work well at low temps

9.  Light intensity/amount  __________ in light, increase in photosynthesis until at _____________ level  Plants still perform photosynthesis in periods without light  Density of Other Plants  Crowded plants compete for _______ and _________  __________ photosynthesis

10.  Converts ___________ into ________  _______________ performs cellular respiration  Happens in _____ organisms  Process is called __________ because it requires ___________  Overall reaction:  _____________ + 6_____ → 6_____ + 6______ + (up to) 38 ______

11.  Found in ________ and _________  Outer and inner _________  _________ - folding of inner membrane  _________ - area inside of inner membrane
