Answer:
Plants are a source of food, fuel and medicine.
Explanation:
In biology, plants are photosynthetic living beings without locomotive capacity whose cell walls are mainly composed of cellulose.
The importance of plants for humans is indisputable. Without them we could not live, since the plants participated in the composition of the gases present in the Earth's atmosphere and in the ecosystems, and are the primary source of food for heterotrophic organisms. In addition, plants have direct importance to man: as a source of food; as building materials, firewood, fuel and paper; as ornamental; as substances that worsen or improve health and therefore have medical importance; and as a consequence of the latter, as the raw material of the pharmaceutical industry.
Plants make carbohydrates through the process of
photosynthesis. When the leaves of the plants absorb the sunlight, they use
this energy to combine water with carbon dioxide. The by-products of mixing carbon
dioxide and water are glucose and cellulose.
<span>Photosynthesis is a unique trait that separate
plants from other living organisms. They can provide the necessary nutrients to
help sustain themselves and survive for longer periods of time. When
carbohydrates are in excess, plants have the ability to store and use them when
one of the ingredients of photosynthesis is not available. </span>
