The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet’s living systems are powered by this process.

Photosynthesis is important for people and animals as oxygen is released as a by product during photosynthesis which is an essential requirement for the survival of animals and human beings. All life forms on earth require oxygen for respiration.

Equally importantly, photosynthesis is the source of oxygen and also removes carbon dioxide from our atmosphere. Oxygen is required for cellular respiration, the process by which food is broken down into energy. Thus, human beings are also solely dependent on photosynthetic plants for their oxygen requirements.

Plants are really important for the planet and for all living things. Plants absorb carbon dioxide and release oxygen from their leaves, which humans and other animals need to breathe. Living things need plants to live – they eat them and live in them. Plants help to clean water too.

Uses of Plants

• Food: Plants are the main source of our food.
• Medicines: Many medicines are made from plants and these plants are called medicinal plants.
• Paper: Bamboo, eucalyptus, etc.
• Rubber: Some plants give us gum like acacia, etc.
• Wood: We get timber and fire- wood from trees.

Plants provide many products for human use, such as firewood, timber, fibers, medicines, dyes, pesticides, oils, and rubber. Plants create habitats for many organisms. A single tree may provide food and shelter to many species of insects, worms, small mammals, birds, and reptiles (see Figure below).

If we talk about the things we get from plants, then are numerous and may take directly or indirectly too. Some of them are oxygen, fruits, vegetables, flowers, nectars, wood, medicines, paper, rubber, cotton, spices, fibre, perfume, manure, cosmetics etc.

They may look harmless enough, but plants can harbor some of the most deadly poisons known. From the death of Socrates by poison hemlock to the accidental ingestion of deadly nightshade by children, poisonous plants have been responsible for human deaths throughout history.

Plants and Their Toxicity to Humans and Pets

Plants are poisonous, or have other nasty features, primarily because they can’t move around to avoid predators (herbivores). Plants have developed an array of weapons (like thorns, hairs) and a lethal chemical arsenal (secondary metabolites) to ward off herbivores while remaining rooted firmly.

While many plants release carbon dioxide, not oxygen, at night, having a few plants in the bedroom will not release enough carbon dioxide to be harmful at all. Also, not all plants release carbon dioxide at night. With proper plant selection, growing houseplants in bedrooms is perfectly safe.
