All the developmental processes occurring in plants involve growth. The growth of plants involves various changes such as the addition of new cells through cell division, an increase in its size and weight, and an irreversible increase in the volume. Therefore, we can define the term growth as a permanent and irreversible change in the size of a cell, organ or whole organism usually accompanied by an increase in its dry weight.

The Algae growing as planktons, benthos, epiphytes and in other common aquatic habitats provide a major source of food to small fishes, aquatic amphibians, and other animals. Since man is dependent on fishes to supplement his diet, the algae prove to be a very important indirect source of human food. The practice of direct consumption of algae as human food is also present around the world. A list of more than hundred species can be made which provide direct food to the human beings, especially to the coastal people of the world. Continue reading 11 Algae that are Used as Human Food.
Auxins include all those chemical substances which promote the growth of stems or coleoptiles sections and decapitated coleoptiles, but in same concentrations are incapable of causing the growth of a whole, undamaged plant. They occur naturally in the plant parts and are also chemically synthesized. The principal naturally occurring auxin is Indole-3-Acetic Acid (IAA) and Indole-3-Butyric Acid (IBA) is a synthetic auxin. Continue reading How do Auxins affect Plant growth?
Long pepper (Piper longum), sometimes called Indian long pepper (pipli), is a flowering vine in the family Piperaceae. It is cultivated for its fruit, which is usually dried and used as a spice and seasoning. The dried fruit of Piper longum is a slender, aromatic plant with creeping jointed stems and perennial woody roots. It is used to make medicine. Indian Long pepper has a taste similar to, but hotter than, that of its close relative Piper nigrum. Continue reading Indian Long Pepper: A Potential Cancer treatment Drug.
We can easily distinguish a living animal from a living plant in our surroundings. We do not find any difficulty in identifying an animal as long as we see it moving, eating and alive. When it comes to plants, we have an image of a structure having spread out appearance with green parts like leaves in our mind. So, to keep it as simple as it was, Carolus Linnaeus classified all the organisms of the world into two Kingdoms i.e. Plantae and Animalia. Continue reading Why is the Two-Kingdom Classification System Inadequate?
