Plants are alive. They grow and die just like other living things on the planet. They need energy, nutrients, air and water to survive. About 350,000 species of plants are estimated to exist.
Photosynthesis: Plants are mostly autotrophs, which means they are organisms that obtain energy from sunlight. This process is called photosynthesis. It is an extremely complex process, one which all life depends on. Plants absorb the sunlight and synthesis the sugar from light, carbon dioxide, and water. Oxygen is the waste product, which plants do not use.
Most plants can be organized according to their seasonal growth patterns:

It is an extremely complex process, one which all life depends on. Plants absorb the sunlight and synthesis the sugar from light, carbon dioxide, and water. Oxygen is the waste product, which plants do not use.
Most plants can be organized according to their seasonal growth patterns:
Annual – These plants live and reproduce within one growing season, meaning they germinate, flower and die in one year. In gardening, annuals are mainly plants that are grown outdoors in the spring and summer. Many annual plants are grown for food.
Biennial – These plants live for two growing seasons. During the first year, the plants grow leaves, stems, and roots. After a period of dormancy, biennial plants grow flowers, fruits, and seeds. Biennials only reproduce in the second year.
Perennial – These plants live for more than two years. Perennial plants are often called herbaceous perennials, as they do not form woody tissue. Perennials continue to reproduce once they reach maturity and often flower every season.
Plants start their life as a seed. The seed is protected by a seed coat. Inside the seed is an embryo, which turns into the plant. The next phase is to grow into a seedling and to grow roots to get the plants nutrients from the soil. Plants also need the right temperature and amount of water to thrive.
All plants have two names: a common name and a botanical name. The common name can vary depending on the country or region. Botanical names are used worldwide and are established by the International Code of Botanical Nomenclature. A plants botanical name is always in Latin.
