What are different factors that affect the growth of plants?

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.  Continue reading What are different factors that affect the growth of plants?

11 Algae that are Used as Human Food.

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.

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.

How do Auxins affect Plant growth?

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?

Why is the Two-Kingdom Classification System Inadequate?

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.
