Study of Plants: Botany
Botany, also known as plant biology, involves studying plant life. Botanists study the parts of the plant, how it grows, reproduces, adapts, and gets nutrition. Botany started with the hunter-gatherer societies that aimed to identify edible, medicinal, and poisonous plants. Modern-day botanists study over 550,000 species of plant life.
Botanists use a classification system to identify and categorize the many different types of species, including the nearly extinct. Scientists will use plants to study genetics. In fact, Gregor Mendel observed pea pods and their flowers to study how traits get passed down from one generation to the next.
Photosynthesis describes the plant`s process of absorbing light from the Sun and creating nutrition; however, not all plants will go through photosynthesis. Plants have a cell wall with a membrane made of cellulose and chlorophyll. Plant breeds range in a variety of sizes.
There are small mosses to gigantic redwood trees that grow over one hundred feet tall. Plants are found everywhere and survived through the process of natural selection to adapt in various climate conditions. Other life forms depend on plant life in order to survive, including humans.

Growing of Plants: Gardening and Horticulture
Gardening is the practice of growing plants. There are various forms of gardening, including indoor gardening, native plant gardening, water gardening, container gardening, community gardening, and garden sharing.
There are many steps to gardening. The first step that a gardener must take is to determine what to grow. To do this, the gardener must decide the purpose of gardening in order to choose the type of plants. The reasons to garden are for recreation, to learn about plants and how they grow, to produce food or natural medicines, and to create ornamental plants for landscaping.
The gardener must then choose a place to garden. Understanding the needs of a plant is very important for gardeners in this step. The needs of a plant can vary by the species but most plants need sunlight, nutrition, water, and space to grow. Gardeners must then cultivate the gardening ground, plant the seeds, tend to the plants and the surrounding area. Growing plants take time and attention. Nurturing each plant`s needs is very important.

There are many different subcategories to consider, including arboriculture, floriculture, landscape horticulture, pomology, viticulture, oenology, and postharvest physiology. Society can use more bright minds to help cultivate the food for the future.

Plants and Water: Hydroponics
Hydroponics uses a method of growing plants with mineral nutrient solutions combined with water in containers without soil. Plants roots are placed in the mineral nutrient solution or perlite, gravel, or mineral wool. Researchers in the 18th century discovered that plants absorb mineral nutrients in water. When the mineral nutrients dissolve in water, the plant roots absorb them from the soil. However, soil is not necessary as long as the mineral nutrients are placed into the plant`s water supply. Osmosis is important for this to occur. It is the process of water moving through a cell membrane. There are three main types of hydroponic solution cultures, including static, continuous-flow, and aeroponics. The medium culture method uses sand, gravel, or rockwool.
