In plant cells, how are chloroplasts and mitochondria related?

• chloroplasts create food; mitochondria break down food and conver it into energy (ATP)

• Chloroplasts package nutrients, mitochondria deliver nutrients to other parts of the cell

• Chloroplasts absorb water, mitochondria store water

• Chloroplasts direct the functions of the cell; mitochondria deliver messages to all the parts of the cell.

Students observe an aquatic plant. Students understand that the bubbles rising from the plant are gases produced during photosynthesis. Which of the following observations provides the BEST evidence that light is the source of energy for photosynthesis?

• The frequency of bubbles increases in bright light and slows to a stop in darkness

• Plants observed in artificial or in natural light were both seen to produce bubbles

• The positioning of the light does not have much effect of the amount of bubbles

• The bubbles always rise to the surface of the water, movign towards the light
