What is a Plant?
The plant is mainly multicellular organisms, predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, plants were treated as one of two kingdoms including all living things that were not animals, and all algae and fungi were considered as plants. There are about 320,000 species of plants, of which the great majority, some 260–290 thousand, produce seeds. Green plants provide a substantial proportion of the world’s molecular oxygen and are the basis of most of Earth’s ecosystems. Plants that produce grain, fruit, and vegetables also form basic human foods and have been domesticated for millennia.
What is a Tree?
The tree is a woody perennial plant, which has many secondary branches at the trunk (stem) with clear apical dominance. At the maturity stage, the minimum height is 3m, and the minimum circumference is 30cm. Shrubs are woody plants, which cannot meet the requirements mentioned above. Most of the trees are flowering plants (Angiosperms) and conifers. There are about 100,000 tree species in the world, and it is about 25% of the total plant species. The majority of the trees are present in the tropical region.
Difference between Plant and Tree
|Plants are associated with the kingdom Plantae.||Trees are tall plants with woody tissue.|
|Plants vary in size. They can be of few inches or closer to the grounds like grasses or long like shrubs.||Trees are generally taller than plants. They can be of few feet or more towering up to 300 feet like coast redwood.|
|Plants have soft, tender stems, single or multiple, or maybe pseudostem.||Trees are known for their hard and woody stems which are known as the trunk, and it provides support in holding the weight of a tree.|
|Most plants are autotrophic but there are exceptions such as the Sundews and pitcher plants||All trees are autotrophic|
|Plants have a comparatively shorter lifespan than trees||Trees have a comparatively long lifespan|
