1. What are the three parts of a ATP molecule?

adenine, ribose, and three phosphate groups

2. Whats is the difference between ATP and ADP?

ATP has three phosphate groups and ADP has two

3. How is energy released from ATP?

Energy is released when a phosphate group is removed from ATP to form ADP

4. Autotroph

an organism that is able to capture energy from sunlight or chemicals and use ut to produce its own food

5. Heterotroph

an organism that obtains food by consuming other living things

6. pigment

light absorbing molecule used by plant to gather the sun's energy

7. examples of pigment

chlorophyll a, chlorophyll b, carotene

8. Why are the leaves of most plants green?

Chlorophyll a and chloropyll b absorb light very well in the blue-violet and red regions. They do not absorb green very well; so plants reflect green light (making them green)

9. Why do leaves change colors in autumn?

Plants contain red and orange pigments (carotene). As the temp drops in autumn, chlorophyll molecules breakdown first, allowing the red and orange pigments to show

10. How do plants the get energy they need for photosynthesis?

Plants obtain energy by absorbing sunlight using pigments located in the thylakoid membranes of the chloroplasts.
