Question

A student wants to test different hormones for a science fair project. Which of the hormones listed below the student use to increase the rate of ripen of fruit?

Gibberlinins
Cytokinins
Auxins
Ethylene
Tropisms are described as the growth or turning movement of a plant in response to an external stimulus. Which pair of tropism and stimulus is correct?

Gravitropism movement towards light
Thigmotropism a response to touch
Phototropism a response to gravity
All are correctly paired.

Answer 1

- Ethylene

- Thigmotropism a response to touch

Step-by-step explanation:

Answer 2

- Ethylene

- Thigmotropism a response to touch

Step-by-step explanation:

1. Plant hormones or phytohormones are of different types with varying functions. They include; auxins, gibberellins, ethylene, abssicic acid etc. Specifically, ETHYLENE or ETHENE is responsible for hastening the ripening process in fruits of plants.

2. Tropism refers to the response of an organisms to stimuli. There are different types of tropism depending on the stimuli source.

- Phototropism is the response of a plant to light

- Thigmotropism is a response to touch

- Geotropism is the response to gravity.
