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.

When exposed to the mucous membranes on the face, biohazards can contaminate the eye as well as enter the circulation and stomach.
- Biological compounds that endanger the health of living things, particularly humans, are referred to as biohazards, sometimes known as biological hazards.
- Medical trash or samples of microorganisms, viruses, or toxins (from a biological source) that may be harmful to human health are examples of biohazards.
- Bacteria, viruses, parasites, and molds or fungi are examples of biological health risks.
- When they come into touch with skin, are eaten, or are inhaled, they can be harmful to human health.
- They have the potential to spread diseases such parasite infections, tetanus, lung infections, and food poisoning.
- The method via which a person can come into touch with a dangerous material is referred to as an exposure pathway. There are three primary exposure routes: direct touch, ingestion, and inhalation.
