Tropisms and Hormones Practice Problems

22 problems

1PRACTICE PROBLEM

Which of the following is the key site of mechanosensation in the Mimosa leaflets?

2PRACTICE PROBLEM

How did the geophysicist Jean-Jacques d'Ortous de Mairan learn that the movement of the sensitive plant (Mimosa pudica) during dusk and dawn is not attributed to phototropism?

3PRACTICE PROBLEM

Many climbing plants have tendrils that respond by coiling and grasping upon touching a hard object. What is the purpose of this behavior among the tendrils?

4PRACTICE PROBLEM

When the leaves of plants such as Mimosa are touched, the cells near the touch stimulus export potassium ions outside the cell, followed by water, causing the cells to collapse. What effect will this have on the Mimosa leaves?

5PRACTICE PROBLEM

The venus fly trap responds to touch by closing its leaves. Once the insect is digested and the stimulus is removed, it again opens its leaves, restoring it to its original position. This response of fly trap is called:

6PRACTICE PROBLEM

Roots rely on touch to determine the direction in which they extend. If they feel an object is in their way, they will grow away from that object. This behavior among many plant roots is called:

7PRACTICE PROBLEM

Which of the following will happen if we remove the gene responsible for the production of cytokinin hormone?

8PRACTICE PROBLEM

In plant seeds, the Abscisic acid hormone promotes seed ________ and gibberellin promotes seed _________.

9PRACTICE PROBLEM

How does the Abscisic acid (ABA) hormone help the plant during extremely hot seasons?

10PRACTICE PROBLEM

Which of the following states the function of plant hormones?

11PRACTICE PROBLEM

Which of the following best reflects the importance of statoliths in plants?

12PRACTICE PROBLEM

Abscisic acid is a plant hormone that helps plants respond to:

13PRACTICE PROBLEM

Ethylene hormone is responsible for short shoots, fat shoots, and increased lateral root growth in seedlings. It is referred to as:

14PRACTICE PROBLEM

All of the following are true statements regarding gravitropism except:

15PRACTICE PROBLEM

16PRACTICE PROBLEM

Which of the following is a function of abscisic acid?

17PRACTICE PROBLEM

_____ is a plant hormone that promotes apical dominance, whereas _____ is involved in breaking apical dominance.

18PRACTICE PROBLEM

Identify the incorrect option about plant hormones.

19PRACTICE PROBLEM

Taproot development is mainly due to _____, but lateral root development is a result of _____.

20PRACTICE PROBLEM

________ is a plant hormone that is associated with the ripening of fleshy fruits.

21PRACTICE PROBLEM

What physical technique will help a plant produce more lateral branches?

22PRACTICE PROBLEM

Match the information in column 1 with the information in column 2, and select an option that includes the correct matching of columns 1 and 2.
