Plants

Plants are one of the main forms of life, including trees, shrubs, vines, grasses, ferns, green algae, lichens and other familiar organisms. Plants can Divided into seed plants, algae, bryophytes, ferns, etc. Green plants obtain most of their energy from sunlight through photosynthesis. Temperature, humidity, light, and fresh water are the basic needs for plant survival.

Seed plants have six major organs: roots, stems, leaves, flowers, fruits, and seeds. Green plants have the ability to photosynthesize - with the help of light energy and chlorophyll, under the catalysis of enzymes, they use water, inorganic salts and carbon dioxide to perform photosynthesis, release oxygen, absorb carbon dioxide, and produce glucose and other organic matter for use by the plant body.

Roots are the vegetative organs of plants, usually located below the surface of the earth. They are responsible for absorbing water and dissolving ions in the soil, and have the function of supporting and storing synthetic organic matter. (Except aerial roots and sessile roots) Roots are composed of parenchyma tissue, vascular tissue, protective tissue, mechanical tissue and meristem cells.
