Answer #1

Answer =

Ethylene is unique as a plant hormone because (1 point)

a)it is only diffused through nearby cells.

Explanation = There are five main types of plant hormones. out of them only ethylene is gaseous hormone.

as it is gaseous in nature, it can diffuse throughout the plant.it is diffused through the membrane into the nearby cells or target cells.

there is no requirement of any transporter to transport the ethylene into nearby cells.

it is synthesized in one cell and diffused to the other cell or nearby cells.

therefore ethylene has unique characteristics that it can diffused through nearby cells.
