Question

Aeroponics is also called as
A. Soilless cultivation of plants
B. Parthenocarpy
C. Vivipary
D. Phytotron

Answer 1

Hint: In order to answer this question, we must first observe each of these options provided below. Which options do you think are similar to the word aeroponics. Try to break the word aeroponic first. Aero means air and ponos means labour. This word is similar to another word called hydroponics where hydro means water.

Complete answer:
To derive the correct answer,we must now define each of these words. Parthenocarpy is the process by which fruits develop from unfertilised ovules which leads to fruits without seeds. Vivipary is a phenomenon that occurs when the seed germinates while it is still attached to the mother plant. Phytotron is an enclosed greenhouse like space where the plants are grown to study interaction in between the plants and the surrounding environment. Aeroponics is the process of growing plants without soil especially in mist. Sometimes aeroponics is also referred to as a part of hydroponics because nutrients are transferred through mist.

Thus, the correct answer is option (A) Soilless cultivation of plants.

Note:
Aeroponics differs from hydroponics or aquaponics because in these methods of plant growth, a liquid medium is generally used for the growth of plants. However in aeroponics, no such medium exists. Aeroponics helps to supply large amounts of oxygen to the growing plants which leads to increase in aeration. As a result the roots get more oxygen and there are less chances of pathogen attack. Aeroponics also help to observe nutrient uptake in plants under certain conditions. Thus, aeroponics has evolved as a desirable tool for observing plant growth.
