Across
  1. 3. Plants that are unaffected by day length
  2. 4. Spectrum that the range of wavelengths are placed on
  3. 5. Stretching caused by an elongation of the internodes in response to low light intensity
  4. 10. The period of exposure to light
  5. 12. Plants that respond to periods of light
  6. 13. he photoreceptor involved in photoperiodic responses and other responses
Down
  1. 1. Give off higher levels of blue wavelengths. They are cool and can be placed close to leaf surfaces.
  2. 2. Give off red and orange wavelengths. They burn hot and should not be placed too close to plants
  3. 6. Some plants flower as days lengthen and nights shorten in the summer
  4. 7. Refers to the color or wavelengths of light.
  5. 8. Refers to the intensity of light
  6. 9. plants that flower naturally in the fall when the day lengths get shorter
  7. 11. light-sensitive pigments
