This is Geumgang Arboretum in Sejong Special Self-Governing City, Chungcheongnam-do, Republic of Korea. Korean culture is pine tree culture. Since ancient times, when our people were born, they tied a golden rope with green pine branches to announce the news, cooked rice by burning pine firewood, used farming tools and household items made of pine trees, lived in houses made of pine trees, and finally ended their lives in coffins made of pine trees. In this way, Koreans can be said to be the first people among mankind to create and develop pine tree culture. Among them, Koreans and pine trees have a particularly deep relationship, and they have had a great influence on the sentiments and temperament of the people who are respectful, solemn, noble, and unchanging, not just in the material use of trees. This influence is also evident in architecture, crafts, painting, literature, folklore, food, etc. Parasitic roots Roots that dig into the stems or roots of other plants to absorb nutrients (e.g., mistletoe, sorghum, etc.) Supporting roots Roots that grow from the stem, not the root, and extend underground to support the stem (e.g., corn, sorghum, etc.) Aquatic roots Roots that have no root hairs and hang down in the water to absorb nutrients (e.g., duckweed, water hyacinth, etc.) Attached roots Plants that grow roots in various places on the stem to attach to other things (e.g., honeysuckle, pine azalea, etc.) Respiratory roots Roots that extend their roots into the air to breathe (e.g., mangrove, larch, etc.) What are seeds? A seed is a tissue that stores nutrients for young plants in the early stages, and seeds of grains or vegetables are called seeds. The size of seeds varies greatly, from the size of a basketball-sized sea palm seed (30cm in size, weighing 20kg) to the size of a tiny orchid seed (0.085mm in size, weighing 0.00081mg) that is too small to be seen with the naked eye. Seed Structure Plants sprout from small seeds, grow leaves and stems, and absorb water and nutrients through their roots. Through these nutrients, plants bloom and bear fruit, and seeds are usually contained in these fruits. Seeds are generally composed of a shell, endosperm, embryo, and cotyledons. Seed Movement Once seeds are mature, plants disperse them widely in various ways. They are carried by the wind, stuck to animal fur or human clothing, carried by flowing water to distant places, or released into the world through the excrement of birds or animals that eat the fruit. • Seeds that are carried by sticking These fruits have hooks or thorns or sticky liquids that stick to the bodies of animals or people and move. Goblin's hook, thief's hook, cocklebur, and thistle. • Seeds that use the wind There are seeds that are blown by fluff, such as dandelions, cattails, reeds, and thistles, and seeds like pine trees and maples that fly far in a weak wind because they are like propellers. • Seeds that float on water, such as lotuses, water lilies, and palm trees, have air pockets in their fruits that allow them to float on water for a long time and travel far. • Seeds that are carried by birds or animals When the seeds of plants are not fully ripe, the flesh of the fruit is bitter or has a foul smell. When the seeds are fully ripe, the flesh becomes beautiful and gives off a fragrant smell, and the birds that eat the fruit excrete the seeds here and there in the mountains. Creeper, cornelian cherry, Japanese maple, and wild cherry • Seeds that spread by bursting pods Beans, red beans, morning glory, balsam, sedge, sedge, and violets are scattered by being pushed out or bursting pods. Birth of plants It is estimated that plants began to live on Earth about 430 million years ago. Early plants could not live away from water to reproduce and maintain moisture, but plants took root on land and evolved through constant challenges and adaptability even in difficult environments. Plants that took root on land for a long time and evolved have enriched the Earth's ecosystem and are now the foundation of the entire ecosystem that many animals depend on and live on. Forests cover about 30% of the Earth's surface and are the most important element of the Earth's system as the habitat for most of the Earth's creatures. Forest plants absorb carbon dioxide in the atmosphere through photosynthesis and store carbon in the form of organic matter in their bodies and soil, which greatly helps suppress global warming. In Korea, 14 times the size of Yeouido. An average of 44 forest fires occur every year, and it takes 50 to 100 years and effort to recover from one forest fire. More than 80% of forest fires are caused by humans, and there are almost no forest fires caused by natural causes such as lightning or volcanic eruptions. #Domestic travel #Travel plan #February travel subsidy event
