A spaceship is designed to support animal life for a multiyear voyage to the outer planets of the solar system. Plants will be grown to provide oxygen and to recycle carbon dioxide. Because the spaceship will be too far from the sun for photosynthesis, an artificial light source will be needed.

What wavelengths of light should be used to maximize plant growth with a minimum of energy expenditure?

• full-spectrum white light

• green light

• a mixture of blue and red light

• yellow light

If carbon dioxide is removed from a plant’s environment, what would you expect to happen to the plant’s production of high-energy sugars?

• More sugars will be produced.

• Fewer sugars will be produced

• The same number of sugars will be produced but without carbon dioxide.

• Carbon dioxide does not affect the production of high-energy sugars in plants

Which event occurs during the light-independent reactions (Calvin cycle) of photosynthesis?

• The chloroplast obtains energy and releases carbon dioxide and water

• The chloroplast captures light energy by generating ATP in the thylakoid membrane

• The chloroplast splits the water molecule and oxygen atoms are released

• The chloroplast uses the energy stored in ATP to make sugar from carbon dioxide

What do chloroplasts use to absorb solar energy?

• mitochondria

• carbon dioxide gas

• molecules of sugar

• the pigment of chlorophyll
