Bromeliads (members of the pineapple family) may be induced to flower by placing the plant in a plastic bag with a ripe fruit. what hormone is responsible for their flowering?

Ethylene gas

Explanation:

The gas is produced in trace amount by plants (virtually every part of the plant is capable of producing ethylene because it is a gas and it diffuses) and has an effect on plants. Ethylene gas is responsible for ripening of fruits, opening up of flowers and senescence and abscission of leaves. Also, when one puts a ripening fruit among unripe fruits, the unripe ones will ripen in a matter of days – because the ripe one produces ethylene gas which has en effect on the others. Commercially, farmers harvest fully developed bu unripe fruits and then expose them to ethylene gas to ripen when they reach the market. This alleviates food spoilage in transit.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
