In the story 'Jack and the beanstalk', Jack grew a beanstalk that grew way into the clouds. If I wanted to try and grow one myself, which plant hormone would I give my beanstalk?
Cytokinesis
Ethylene
Auxins
Gibberellins
Which plant hormone is a gas?
auxin
gibberellin
ethylene
cytokinin
This hormone may oppose the effects of auxins. This is why you trim the tops off of stems (where auxin is produced) to have more lateral growth.
abscisic acid
auxin
cytokinins
gibberellin
ethylene
My tomato seed wont grow. Which hormones can I use to make it start growing?
Auxins
Cytokinins
Ethylene
Abscisic acid
Gibberellins
The figure below above shows an experiment to study the effect of auxin towards the growth of the coleoptiles. Which of the following conclusions are true about the experiment?
I, II and III only.
I, III and IV only.
II, III and IV only.
I, II, III and IV.
Apical dominance which suppresses lateral bud development is caused by what hormone?
auxin
gibberellin
ethylene
imbibition
What is the role of auxin that causes a plant to bend towards light?
The concentration of auxin in the plant increases when there is light.
Auxin causes uniform growth on every stem.
Auxin causes cells that are on the dark side to grow faster.
Auxin causes the increase in the number of plant cells.
The figure above shows an experiment that is done on two plants of the same species. Both plants are left in the open. What will happen to the two plants after two weeks
I Plant B bends towards the opening of the box.
II The auxin in stem A is distributed uniformly.
III The auxin in stem B is not distributed uniformly.
IV Plant A bends to the right.
The diagram shows the same plant. Which of the following statements is not true
Plant b will be shorter than plant A
plant b produces lateral branches since the apical bud is removed
plant A shows apical dominance
plant a produces abscisic acid to prevend side branches from forming
In the story 'Jack and the beanstalk', Jack grew a beanstalk that grew way into the clouds. If I wanted to try and grow one myself, which plant hormone would I give my beanstalk?
