A classroom has no windows. Which type of plant would survive best there?

Why can organisms near hydrothermal vents carry out photosynthesis?

• They evolved to use very low levels of light from the vents

• They store sunlight from the surface

• They don’t need light

• They use heat instead of light

Which produces healthier plants: sunlight or artificial light, and why?

• Sunlight, because it provides the full energy spectrum

• Artificial light, because it is brighter

• Both are equal in energy

• Neither, because plants only grow outside
