Plant Hormones Deficiency Effects

What are the effects of auxin deficiency on plant growth?

• Auxin deficiency promotes rapid growth

• Auxin deficiency inhibits growth, leading to stunted growth, abnormal leaf development, and poor root formation.

• Auxin deficiency causes increased root growth

• Auxin deficiency leads to enhanced leaf development

How does gibberellin deficiency impact seed germination?

• Gibberellin deficiency leads to excessive seed germination

• Gibberellin deficiency speeds up seed germination by bypassing dormancy

• Gibberellin deficiency inhibits seed germination by preventing the breaking of dormancy and the stimulation of enzyme production.

• Gibberellin deficiency has no impact on seed germination

What is the role of cytokinin deficiency in leaf senescence?

• Cytokinin deficiency delays leaf senescence.

• Cytokinin deficiency has no effect on leaf senescence.

• Cytokinin deficiency accelerates leaf senescence.

• Cytokinin deficiency causes leaf growth.

Describe the impact of abscisic acid deficiency on stomatal closure.

• Abscisic acid deficiency results in reduced ability of stomata to close properly.

• Abscisic acid deficiency has no impact on stomatal closure

• Abscisic acid deficiency leads to increased stomatal closure

• Abscisic acid deficiency causes stomata to open wider

What happens when there is a deficiency of ethylene in fruit ripening?

• Fruits may experience delayed or incomplete ripening.

• Fruits will ripen faster than usual.

• The fruit will become overripe and inedible.

• The color of the fruit will not change during ripening.

How does brassinosteroid deficiency affect plant height?

• Brassinosteroid deficiency has no impact on plant height

• Brassinosteroid deficiency increases leaf size but not plant height

• Brassinosteroid deficiency inhibits cell elongation and division, causing stunted growth in plants.

• Brassinosteroid deficiency promotes excessive cell elongation leading to taller plants

Explain the role of traumatic acid deficiency in wound healing.

• Traumatic acid deficiency has no impact on wound healing

• Traumatic acid deficiency can impair wound healing by affecting collagen synthesis.

• Traumatic acid deficiency enhances wound healing by promoting inflammation

• Traumatic acid deficiency leads to faster wound closure

What specific growth processes are affected by auxin deficiency?

• Leaf senescence, stem elongation, and lateral root formation

• Cell elongation, root initiation, and apical dominance

Why is gibberellin important for seed germination?

• Gibberellin inhibits seed germination by suppressing enzyme activity

• Gibberellin promotes embryo growth, cell elongation, and enzyme activation essential for seed germination.

• Gibberellin has no impact on seed germination

• Gibberellin causes seed dormancy instead of promoting germination

How does cytokinin deficiency contribute to leaf aging?

• Cytokinin deficiency accelerates leaf aging by reducing cell division and promoting senescence.

• Cytokinin deficiency delays leaf aging by increasing cell division and preventing senescence.

• Cytokinin deficiency has no impact on leaf aging.

• Cytokinin deficiency leads to leaf discoloration but does not affect aging.
