Question

“What do Plants need to Grow?”
Support an argument that plants get the
materials they need for growth mostly from
air and water but not from soil. Set up an
experiment. Take five small plants for the
experiment and record the observations in
your book.

Answer 1

Answer:

It's simple really—plants get the materials they need to grow cheifly from air and water! Sunlight provides the energy plants need to convert water and carbon dioxide (CO2), a major component in air, to carbohydrates, such as sugars, in a process called photosynthesis (Fig. 3).

Plants need energy from the sun, water from the soil, and carbon from the air to grow. ... They absorb carbon dioxide from the air. This carbon makes up most of the building materials that plants use to build new leaves, stems, and roots. The oxygen used to build glucose molecules is also from carbon dioxide.

Plants, like all living organisms, have basic needs: a source of nutrition (food), water, space in which to live, air, and optimal temperatures in order to grow and reproduce. For most plants, these needs are summarized as light, air, water, and nutrients (known by the acronym LAWN).

Answer 2

Answer:

for the second part of the question, I  think that the plants get more material to grow because the air gives them the physical building of them, and too the molecular structure is also provided by the air.
