Chapter 39, Problem 10TYK
Summary Introduction
Introduction: Phytochrome is a blue-green pigment or a photoreceptor present in plants. These pigments regulate several light-dependent developmental processes in plants. Some are germination of seeds, timing of flowering, and elongation of seedlings. Phytochrome is expressed in most of the plant tissues.

Which of the following is the function of cytokinin?
A. activation of defense response from biotrophic and hemi-biotrophic pathogens
B. structurally related to animal steroid hormones for growth and development
C. long distance (root-to-shoot) signals for nitrogen assimilation
D. defense from necrotrophic pathogens and herbivore insects
ties of the brain and spinal cord
B. Match the hormones that are supposed to be added to a plant in order to achieve the following
results:
a. Auxin
b. Gibberellin
c. Cytokinin
d. Abscisic Acid
e. Ethylene
19. unpollinated flowers are treated with this hormone so ovary enlarges and becomes a
seedless fruit
20. substitute for temperature or light cues in plant seeds to get them to germinate
21. black spots on banana skin are spots where these are produced inducing ripening
22. seeds/bulbs stay dormant during winter to ensure survival of the plant when it germinates
23. most grape growers spray this in vines to increase length of branches between fruit clusters
for more air spaces among fruits to lower fungal infections
24. sprayed on cut leaves and stems so they will remain green longer while unsprayed leaves
will tum yellow and die

a. Can harvest its own energy from sunlight.
b. Can harvest its own energy from inorganic chemicals.
c. Grows well on minimal media.
d. Requires nutritional supplements to grow on minimal media.
