11th Grade Plant Hormones Quizzes, Questions & Answers

11th Grade

Top Trending Plant Hormones Quizzes

Reaching New Heights: Gibberellins Function

Some of the most dramatic effects a plant hormone can have are visible without a microscope: seeds breaking dormancy, stems elongating rapidly, flowers forming ahead of schedule. Gibberellins function encompasses all of these...

Questions: 20 | Attempts: 12 | Last updated: Mar 8, 2026

Sample Question 1
What is the primary role of gibberellins in a developing plant stem?

Promoting cell elongation and division

Stopping the plant from growing too tall

Turning the stem into a flower

Protecting the stem from insects

Creating sugar through photosynthesis

Sample Question 2
Gibberellins are the primary hormones responsible for triggering the germination of a dormant seed.

True

False

Sample Question 3
Which of the following are known effects of gibberellins on plant development?

Stimulating the growth of larger fruit

Inducing "bolting" (rapid stem growth)

Breaking seed dormancy

Causing leaves to fall off in autumn

Promoting the production of digestive enzymes in seeds

Recent Plant Hormones Quizzes

The Fountain of Youth: Cytokinins in Plants

While much of plant growth is driven by elongation, the decision to actually divide a cell requires a different molecular signal entirely. Cytokinins in plants drive cell division in meristems, delay leaf senescence, regulate...

Questions: 20 | Attempts: 10 | Last updated: Mar 8, 2026

Sample Question
What is the primary cellular process stimulated by the presence of cytokinins?

Cytokinesis (cell division)

Photolysis of water

Glycolysis

DNA denaturation

Apoptosis
