In 3-5 sentences and in your own words, describe why a green banana will start to ripen and turn yellow much more quickly if a brown banana is placed next to it.
Hormones communicate between plants and signal to ripen further the release of ethylene helps in this ripening as well.
Explanation:
When a green banana is placed closely to a brown banana it will ripen more quickly and would turn yellow because the brown banana releases a chemical called ethylene.
Ethylene is gaseous is nature and is thus, able to affect plants that lie close to it and this is the reason why ethylene is known as a fruit ripening hormone.
The amount of ethylene increases in fruits as the fruit further ripens and hence, when placed next to a brown banana the green banana will ripen more quickly and turn yellow.
