Needless to say, plants have a lifespan, and they also age. As far as human beings currently know, there is no kind of plant on the earth that can live forever, maybe some plants have a long lifespan, but they also always have an end day, not only plants, all creatures in nature are the same, their life span will always end one day, some people may say, viruses can live forever, is this the case? Obviously not, in general, most viruses are not long-lived, and even if there are some that are long-lived, they will eventually die with the host.
Generally speaking, the life of any living thing is finite, and if it is infinite, then they will not occupy the earth long ago after countless generations of reproduction. But there is still no kind of living thing that fills the earth, which means that immortal beings do not exist. The limit of the age of life depends first on its physical environment and then on the biological nature of life, there is a saying that the maximum age of life on a planet is determined by the speed of rotation of the planet, the higher the rotational speed, the longer the lifespan.
Although I don't know how credible this statement is, it also shows that living things will not live forever, after all, the rotation speed of the planet is always limited. <>
There are no immortal creatures in the world, and plants are no exception. Even plants that live thousands of years can die, but in general, plants live longer than animals, mainly because of the difference between stem cells, which are essential for the continued production of new cells. Despite the importance of stem cells in promoting plant growth and development, many questions about their strict molecular control still do not lend reason.
It is known that stem cells from certain tissues in plant roots are less sensitive to DNA damage, and these cells have original intact copies of DNA, which can be used to replace damaged cells if necessary. And that's why most plants have a long lifespan. <>
The universe has its own laws, and if this law is violated, things will cease to exist.

Plants have a lifespan, and they also age. Plants also have a lifespan, but they live much longer than animals and age more slowly. A tree can live for thousands of years, and that's when they also enter the aging stage.

Plants, especially thousand-year-old trees, give people the feeling of endless life and immortality, which is actually an illusion. Everything that is living in nature has a lifespan, and the same is true for plants. Populus euphratica in Xinjiang, known as "a thousand years of not falling, a thousand years of immortality, a thousand years of immortality", has a very long lifespan.
Stunted plants have a long lifespan, and gymnosperms have a longer lifespan, such as ginkgo biloba, which can live up to thousands of years, but there is almost no 10,000-year-old ginkgo, because even if it does not die naturally, it will be eroded by nature (such as sandstorms, frost, insect infestations, **, volcanoes, etc.) or man-made destruction. Even under the right conditions, it rarely has a lifespan of thousands of years, and a thousand years is an ancient tree. Because this is determined by its growth cycle.
For example, peach trees, which do not bear fruit in the first three years, are young trees; After three years, the fruit will be hung, and in a few more years the vigorous growth period will be carried out, and in a few years the yield will drop significantly, enter the senescence period, and in a few years, some branches will die, and the life of the tree will be almost at the end of its life.

Plants have a lifespan, and they also age. Everything that is living in nature has a lifespan, and the same is true for plants, but common plants have a longer lifespan.

Of course, plants have a lifespan, such as epiphany, epiphany only blooms once in the morning for a few hours in the morning, that is the most shining time in its life, sunflowers that turn to the sun, after two years of maturity, they no longer turn towards the sun, and then the fruit is ripe and shrinks and grows old.
-
Everything in nature has a lifespan, but some poplars, ginkgo biloba, etc. can survive for hundreds or thousands of years, and do not seem to age, which is waiting for scientists to study the genes and tissues of plants to determine the secret of their longevity.

Plants also have a lifespan, and of course they will also age, and most plants will die in a few years.

How long do plants live, the lifespan of each plant is different.
Sequoia is one of the most ancient and valuable trees in some of the Americas. The leaves of the redwoods are elongated, pinnate and alternately arranged, verdant and evergreen. There are some native redwoods on the north coast of California, USA, the age of the trees is about 2000 to 3000 years, the height of the tree is about 80 meters, the chest circumference is more than 20 meters, the tallest sequoia is about 104 meters high, the diameter is more than 6 meters, so it is called "the long-leaf world".
Short-lived chrysanthemum is also called "tooth grass". In arid deserts, rain is scarce, and many desert plants adapt to arid environments with degraded leaves and the ability to conserve water. The short-lived chrysanthemum is different in that it has developed a special habit of rapid growth and maturity.
As soon as there is a little rain in the desert and the ground is a little wet, the seeds of the short-lived chrysanthemum will immediately complete the whole process of germination, rooting, growth, flowering, fruiting and death. The entire life cycle of a lifetime is only a short period of three or four weeks.
Herbaceous plants generally only live for 1-2 years, or even only one season.

Among our common plants, fungi have the shortest lifespan comparatively; followed by rice, corn, barley and other grasses; Trees live significantly longer than other plants. However, among the tall trees, pine, cypress, fir and other trees have a significantly longer lifespan than fruit trees, camellia trees and other cash crops.
It is already known that the lifespan of apple, grape, pear, jujube, walnut trees is 100-400 years, maple, elm, birch, camphor trees, etc. are 500-800 years, and pine, cedar, cypress, ginkgo, spruce, giant sequoia, etc. are 1500-4000 years. The 4,000-year-old giant sequoia is not the longest. According to relevant information, the longest-lived tree may be considered the dragon's blood tree.
It is an evergreen tree that was first found in Africa and can grow to more than 20 meters tall. One of them, a dragon's blood tree growing on Orta Island in the Canary Islands of North Africa, has a lifespan of more than 6,000 years, which is still 500 years ago. Unfortunately, it did not survive to this day and was destroyed in a major storm in 1868.
If it hadn't been for that wind, it might still be alive today, even two or three centuries or longer.

This is a question that even the best doctors in the world can't give you an answer.
A vegetative person may die at any time, or he may remain alive until his lifespan is at the end of his life, when the organs of the body are senile.

The world's longest-lived plant - dragon's blood tree In the Xishuangbanna Institute of Tropical Botanical Research, there is a slow-growing and drought-tolerant light-loving tree, which has a stubby stem, gray and white longitudinal cracks, and lush branches and leaves. This kind of tree, when with a knife on the top, it will flow out like the sap of human blood, for this reason, people call this bleeding tree "dragon's blood tree" (also known as blood exhaustion), the sap of the dragon's blood tree can be used in medicine, the main treatment of bruises, blood stasis pain, rheumatism and numbness, **miscellaneous diseases and other diseases.
According to expert research, the dragon's blood tree can reach an age of more than 8,000 years, making it the longest-lived tree on earth.
