Botany
1. Botany is a branch of biology that involves the scientific study of plant life. Botany covers a wide range of scientific disciplines concerned with the study of plants, algae and fungi, including structure, growth, reproduction, metabolism, development, diseases, chemical properties, and evolutionary relationships between taxonomic groups. Today botanists study over 550,000 species of living organisms.
2. The study of plants is vital as they are a fundamental part of life on Earth, which generates oxygen, food, fibres, fuel and medicine that allow humans and other life forms to exist. Through photosynthesis, plants absorb carbon dioxide, a greenhouse gas that in large amounts can affect global climate. Additionally, plants allow us to produce food to feed an expanding population, produce medicine and materials, understand environmental changes more clearly.
3. Virtually all foods eaten come from plants, either directly from staple foods and other fruit and vegetables, or indirectly through livestock or other animals, which rely on plants for their nutrition. Plants are the fundamental base of nearly all food chains because they use the energy from the sun and nutrients from the soil and atmosphere, converting them into a form that can be consumed and utilized by animals.

Определите основную идею текста.
- The task of botany is to produce food to feed the increasing population, to make medicine and materials, and to change our global climate.
- It’s necessary to study plants life as all food comes from plants, either directly from staple foods or indirectly through livestock used by it for nutrition.
- Plants contribute much to environment protection, provide people with food, medicine, fuel and fibres, represent the main food source for other living beings.
- Plants play a crucial role in global climate through the process of photosynthesis, in the course of which they absorb carbon dioxide generating oxygen.
