Plant life activity refers to the process that plant seeds germinate, branch, grow leaves, bloom and bear fruit on the basis of metabolic activities such as water, mineral nutrition, photosynthesis and respiration.
These life activities are interrelated, interdependent and mutually restrictive. Therefore, the life activities of plants can be roughly summarized into three aspects: growth and morphogenesis, material and energy metabolism, and stress physiology.
The roots of plants often show hydrotropism, especially when the soil is dry and the water distribution is uneven, the roots always grow in wet places with water, and the roots are densely distributed in wet areas.
Brief introduction of the factory:
Plants are one of the main forms of life, including trees, shrubs, vines, grasses, ferns, green algae, lichens and other familiar creatures.
Plants can be divided into seed plants, bryophytes and ferns. It is estimated that there are about 450,000 existing species.
Most of the energy of green plants is obtained from sunlight through photosynthesis, and temperature, humidity, light and fresh water are the basic needs of plant survival.
Angiosperms have six organs: roots, stems, leaves, flowers, fruits and seeds. Green plants have the ability of photosynthesis-with the help of light energy and chlorophyll, under the catalysis of enzymes, water, inorganic salts and carbon dioxide are used for photosynthesis, releasing oxygen and producing organic substances such as glucose for plants to use.
