Yes, a tree is a living organism.
Anything that has life is considered a living being. For example– humans, trees, dogs, etc. Things which have no life in them are considered non-living. For example– stone, mountain, watch, etc.
No, plants don't have any specialized tissue to perceive pain. In fact, that's why their cells don't even realize that they've been parted from plant body. They live while parted away from plant till there's enough water left for metabolism.
Yes, but not all of it. Only 1% of a tree is living, and the rest of the tree is made of non-living cells. The non-living parts of the tree provide necessary support to keep the living parts alive and growing.
In a sense, plants are able to think by perceiving their environment and making decided changes in order to thrive. But when it comes to whether plants can think, plant thought is not at the level of sentience, or self-awareness, like it is for humans and animals.
There is also fairly robust evidence that plant cells can perceive and respond to pressure waves, like the kind that are generated by sound in the environment and touch — like, say someone walking up to a tree and hugging it.
There is no scientific evidence that plants possess consciousness or are sentient.
The Scriptural Definition of Life
Nowhere are plants, bacteria or fungi ever referred to as having nephesh. Life is also described as being “in the blood” or the “flesh”, or having “breath”. Plants, bacteria, fungi and even insects do not fit into any of these criteria and so are not alive in a biblical sense.
Trees do the opposite. So they take in what you exhaled. They take in carbon dioxide and they give out oxygen and this is during the day. So during the day they take in carbon dioxide and they release oxygen.
Scientists have recorded plants producing airborne sounds in response to lack of water or having their stems damaged. The ultrasonic pops occurred in rapid bursts, which differed depending on the type of stress the plant was experiencing.
In plant biology, plant memory describes the ability of a plant to retain information from experienced stimuli and respond at a later time. For example, some plants have been observed to raise their leaves synchronously with the rising of the sun. Other plants produce new leaves in the spring after overwintering.
— Even without nerves, plants can sense when something touches them and when it lets go, a Washington State University-led study has found.
But scientists are still unsure of whether it is the water balance, lack of sunlight, energy conservation, or another factor that triggers the tree to lower it's branches. While the trees may not sleep in quite the same way we do, this study does provide a clear indication that trees definitely rest at night.
Trees are more than just plants: they are complex living organisms that play an important role in the health of our planet and enrich our lives in different ways.
Through a process called photosynthesis, leaves pull in carbon dioxide and water and use the energy of the sun to convert this into chemical compounds such as sugars that feed the tree. But as a by-product of that chemical reaction oxygen is produced and released by the tree.
In the Sermon on the Mount, Jesus refers to 'κρίνα τοῦ ἀγροῦ' 'lilies of the field'. True lilies were not native to Galilee and it is believed that Jesus was referring to a common field flower, whose beauty was adorned by God; 'even Solomon in all his glory was not arrayed like one of these. '
In Jainism. Jains believe that plants have souls (jīva) that experience only one sense, which is touch. The Ācārāṅga Sūtra states that "plants ... and the rest of creation (experience) individually pleasure or displeasure, pain, great terror, and unhappiness" (1.1.
In the Gospel of Matthew the parable is as follows: The Kingdom of Heaven is like a grain of mustard seed, which a man took, and sowed in his field; which indeed is smaller than all seeds but when it is grown, it is greater than the herbs and becomes a tree, so that the birds of the air come and lodge in its branches.
Amazingly, despite being some of the largest living things on the planet, only about 1% of a tree is actually alive and made up of living cells. This living portion of the tree is found beneath the bark and is called the cambium layer.
So, the answer to this age-old question seems to be simple: it depends on how we define 'sound'. If we define it as 'vibrating air', the falling tree makes a sound. If we define it as a conscious experience, the lonesome falling tree does not make a sound. There, problem solved.
Some trees may only live for a few decades or less, while others can survive for centuries or even millennia. Generally, the lifespan of a tree ranges from 30 years for fast-growing species to over 5,000 years for the oldest known trees.
The Bottom Line. The reason plants can't feel pain is because they lack nervous systems and brains. This is also the precise reason why so many nonhuman animals, including the many that we kill by the millions every day for food, can and do feel pain.
In biology, it is generally agreed that organisms that possess the following seven characteristics are animate or living beings and thus possess life: the ability to respire, grow, excrete, reproduce, metabolize, move, and be responsive to the environment.
On May 10, 1901, Acharya Jagadish Chandra Bose proved that plants are like any other life form. Bose proved that plants have a definite life cycle, a reproductive system and are aware of their surroundings. The demonstration took place in the Royal Society in London, England.
