Definition of Plant
The multicellular eukaryotes are plants (Plantae), which are one of the ecosystem's important life forms. They are characterized by photosynthetic feeding (except for a few parasitic plants, insectivorous plants) where water, sunlight, minerals, and carbon dioxide are used to generate chemical energy. Secondly, they are immobilized, leading to a stationary life. In a localized area, they can grow widely.
Plants have a well established vascular system which helps in transporting water and food throughout the body. Their height ranges from a few millimetres (duckweed) to much greater than 90 meters (giant sequoias).
There are plant varieties that are found in various regions of the world; they are present in the dry, cold, underwater, high, low, etc. areas.
There are approx 390, 900 plant species recognized, and more to be discovered in various parts of the world. They all serve the life form and support it in many ways. Both forms of energy consumed by a living organism depend directly or indirectly on the photosynthesis process carried out by green plants.
Definition of Tree
A type of woody plant which continues its development (perennial). Trees (Plantae) have a single trunk that carries their weight, woody tissues are in the trunk, and a tree's trunk also produces the secondary limbs or branches.
One can define the tree physiologically as a tree's trunk has dead tissues that help to support the treetop's weight. Within the tissue band, the xylem and phloem are present and help in moving food and water from the roots to other areas of the tree. Inside the cambium, xylem is present, while phloem is present outside the tissue.
Every year, the tree grows two annual rings; one is in summer, which is a dense layer known as summerwood, and the second is in spring, which is a thin and vast layer known as springwood types.
Trees represent the largest and fundamental diversity on Earth. The biosphere depends directly or indirectly on the activity of the tree, such as digestion, photosynthesis, recycling, as well as its products (pulp, fruit, leaves, flowers, wood, etc). There are approximately 3 trillion mature trees all over the world.
What is the Difference Between Plant and Tree?
Did you know?
As they slow and filter rainfall, trees help enhance our water quality.
Trees need water to live, just like humans — and they drink a lot of it. A large tree will absorb 100 gallons of water from the ground in a single day and release it as oxygen and water vapour into the air. Remember that there are many factors that play a role, such as a tree size, tree species, humidity, temperature, exposure to the sun, etc.
While many characteristics are shared by plants and trees, they are easy to tell apart. Generally, trees are much larger in size than plants. Trees also have only one woody stem and are referred to as a trunk. Plants typically have several roots, but they are readily bendable and somewhat weaker. Another distinction is that, on the lower parts of their body, trees have few leaves or branches.
Towards the apex of the centre, most of the leaves are present. Plants, although they are closer to the ground, still have leaves. Some plants are composed entirely of leaves as well. Trees have a very small range of shapes, ranging from triangular and rounded forms to columnar varieties. In contrast to trees, plants have a broader variety of shapes. These vary from scrambling vines to thickets or clumps. So, there is a major difference between tree and plant.
