Question 1 Do plants need soil for growth? Tell me the truth. Through this experiment, do you know what conditions plants need to grow?

Question 1: Soil plants need soil, or sand, clay, etc. But some plants need little soil, such as some ornamental plants planted in rockeries, but they all need soil more or less because plants cultivated in soil need to absorb roots and nutrients from the soil.

Hydroponics do not need soil, because they can directly absorb nutrients from water, and because hydroponics are raised overhead and do not need to take root.

Question 2: Plants need sunlight, water, air, suitable temperature and corresponding minerals.
