Answers:1. sunlight (energy), chlorophyll (to absorb the light), and a lot of enzymes found inside the chloroplasts of plants. http://en.wikipedia.org/wiki/Photosynthesis 2. By the cytochrome bf complex in the thylakoid membrane of the chloroplast http://en.wikipedia.org/wiki/Chemiosmosis#In_plants 3. Because the phytosynthetic pigments carry out the photosynthesis (sounds like a trick question). 4. The enzyme ATP synthase http://en.wikipedia.org/wiki/ATP_synthase 5. The phosphate groups are bound to the 2-deoxyribose (sugar), on the 3rd and the 5th carbon atoms. The backbone is sugar-phosphate-sugar-phospate-sugar, etc. http://en.wikipedia.org/wiki/Dna I hope that was helpful! Next time, it might be better to split up the question into 5 questions. That way more people will be motivated to answer (and earn 5 times the points).

Answers:The only thing I can think of is for use in electron microscopy. When an electron microscope is used, the sample to be looked at is covered in metal ions, typically gold. The metal coating is needed to make the sample electrically conductive. An electron microscope allows for really cool looking pictures of super-small things, like bacterial cells or hairs on the leg of a flea.
