Do plants need soil for photosynthesis?

Answer 1

Marine plants do not need soil.

Lichens can grow on rocks where there is no soil. However, they are slow-growing. Most land-based plants do need soil, however.

Plants which normally grow in soil can be successfully grown hydroponically (in water only). This is achieved by providing nutrients (fertilizers) and air to the water which meet the nutritional needs of plants being grown.

Answer 2

No. Many plants can be grown in soilless environments as long as the nutritional needs are met. spagnum or peat moss can be used. Shredded paper and sawdust can also be used. Hydroponics is the science of growing plants in nothing but water with nutrients added. Soil is the best medium for most plants because of the needed bacteria that resides in soil and allows nitrogen exchange to take place into the roots.

Answer 3

[1] If plants were people, they'd be feeding through their feet. For it's plant roots that take in the nutrients and water that's sent throughout the above-ground plant parts. [2] They need access to air, nutrients such as minerals, and water. [3] They need protection to anchor the plant and to spread out. [4] Soil meets those needs by way of air and water pore spaces. It meets those needs by way of nutrients from infiltration and percolation of water, which contains hydrogen, nitrogen, and oxygen from the air. And it meets those needs by way of nutrients from the breakdown of dead and dying organisms such as earthworms and microarthropods. And it also meets those needs by way of protection from extremes of wind, temperature, and moisture. [5] It's also possible, however, for plants to grow in the air, soil-less mediums, and water as long as the basic needs of growth and protection are met.

Answer 4

No. There are high-tech farming methods that uses aeroponics (roots in the air) and hydroponics (roots in the water). The soil is the thing that holds the plant, so without the soil, given that it is well taken care, it can still grow

Answer 5

No it is not needed. In the rain forest, plants grow on the branches of trees. Since it cannot take water from the soil. It takes in moisture from the air and uses it as water.

Answer 6

Not always. Otherwise hydroponic gardening wouldn't work.
