Multiple Choice

Which signaling molecule stimulates fruit ripening?

Auxins

Ethylene

Phytochromes

Gibberelins

Verified step by step guidance

Understand the role of each signaling molecule listed: Auxins, Ethylene, Phytochromes, and Gibberellins.

Auxins are primarily involved in cell elongation, root growth, and differentiation. They are not directly linked to fruit ripening.

Ethylene is a gaseous plant hormone known for its role in promoting fruit ripening and other processes like leaf abscission.

Phytochromes are involved in the regulation of plant development in response to light, not directly in fruit ripening.

Gibberellins are involved in promoting stem elongation, seed germination, and flowering, but not specifically in fruit ripening.
