Test Your Knowledge of Plant Hormones

1. Plants produce auxins to control growth in response to light and gravity.
2. Shoots show positive phototropic response and negative gravitropic response.
3. Roots show negative phototropic response and positive gravitropic response.
4. Auxins promote cell elongation in shoots and inhibit it in roots.
5. Unequal distribution of auxin causes unequal growth rates in roots and shoots.
6. Auxin is mostly made in the tips of growing shoots and diffuses to the region behind the tip.
7. Auxin concentration on the shaded side of a shoot causes it to bend towards light.
8. Gibberellins initiate seed germination and induce flowering and fruit growth.
9. Ethene controls cell division and ripening of fruits.
10. Gibberellins and ethene are used commercially.

Test your knowledge on plant hormones with this quiz! From auxins to gibberellins and ethene, this quiz covers the basics of how plants control growth and respond to stimuli. Learn about phototropism and gravitropism, how auxins affect cell elongation, and the commercial applications of plant hormones. Get ready to grow your understanding of plant biology!
