1, which has the ability of photosynthesis.
Photosynthesis is a biochemical process in which green plants use photosynthetic pigments such as chlorophyll and some bacteria to convert carbon dioxide and water into organic matter for energy storage and release oxygen under visible light irradiation. At the same time, there is an energy conversion process in organic matter that converts light energy into chemical energy. There are many factors that affect plant photosynthesis, such as light, humidity, moisture, oxygen content, mineral nutrition and so on. The effect of light on photosynthesis is very important.
It has six organs.
Plants have six main organs: roots, stems, leaves, flowers, fruits and seeds, and each organ has its own function, so that plants can grow normally.
3. Roots are vegetative organs.
Roots are the vegetative organs of plants, which are usually located below the surface. They are responsible for absorbing water, inorganic salts and soluble small molecular organic substances in the soil, and have the functions of supporting, reproducing and storing synthetic organic substances.
Common plant species:
1, gymnosperms
Gymnosperms have a long history of development and are a kind of paleontology. It first appeared in Paleozoic, especially from Mesozoic to Cenozoic, and spread all over the continents. It is the most important plant on land, mainly including trees, shrubs, vines and other types, and also divided into evergreen linear, needle-shaped and scale-shaped plants.
2. Angiosperm
During the prosperity and decline of gymnosperms, angiosperms developed, which was also a plant 100 million years ago, and later developed into the most diverse and widely distributed plants. It is a flowering plant, which reproduces offspring through flowers, accounting for almost half of the plant species.
3. Bryophytes
Moss is also a species of plants, with almost 18000 species, which can be divided into three categories: moss, moss and Ceratophyllum. This plant is generally only 2 to 5 cm tall, and the tallest is 30 cm tall. It is a widely distributed and weather-resistant plant, which can be found in polar and tropical regions and likes to grow in humid environment.
