Question
Chapter 33, Problem 3TYK
Summary Introduction
Introduction:
The auxin is a plant hormone produced by the apical meristems of shoot and root. It functions to promote stem elongation and also enhances apical dominance.

Identify the wrong match
a.Senescence —Both auxin and ABA promote it
b.Apical dominance — Auxin induces and Cytokinin counteracts
c.Dormancy — Both ethylene and GA break it
d.Callus differentiation — Auxin and cytokinins
1) You exposed a plant to a light that shines on the right side of a plant. Choose the statement that best describes the plant growth towards the light.

B. Auxin moves from the lighted side to the shaded side where it stimulates growth.
C. Auxin moves from the shaded side to the lighted where it stimulates growth.
D. Auxin moves from the shaded side to the lighted side where it inhibits growth.
2)Select a plant hormone that responsible in inhibiting protein breakdown and stimulating RNA synthesis.
A. Abscisic acid
B. Ethylene
C. Cytokinins
D. Auxins
