A chemical reaction that occurs between wood, fuel and oxygen when the fuel used reaches the ignition point is called fire. Ignition point of a substance means the temperature at which the reaction occurs. When wood starts to heat using some external source, the cellulose material that is present in the wood decomposes, which then
Breathing is the process of taking in oxygen from surrounding and giving out carbon dioxide. The breathing process is different in different animals like in reptiles, mammals, birds, aquatic animals, etc. Frogs just after birth are called tadpoles. They breathe through gills and skin. It sounds weird but this is a part of incredible Nature.
Zygote is the basic cell formation in any cellular organism which leads to the development of multi-cellular organisms. It is formed when two gametes combine together by sexual reproduction. In single cell organisms, these are the main component of the organisms which are later divided into two to form offspring. Zygote is the embryo which
Photosynthesis is the process of grasping light energy and converting it into chemical energy in plants. In other words, we can also say photosynthesis is the breathing process of plants. It is just the right opposite to the human breathing system. Humans take inhale oxygen and release carbon dioxide whereas plants take carbon dioxide in
How does it happen that a bird on a wire doesn’t get shocked? When the bird perches on a live wire, its body becomes charged for the moment; it’s at the same voltage as the wire. But no current flows into its body. Electricity must have a path in order to travel. A power line

Plants need water to survive, which is an idea we’re probably already familiar with. Cactuses are thrifty plants that live in dry regions. They may not get much moisture where they live, but they manage to make the most of what they do get. Cactuses (sometimes also called ‘Cacti’) are types of plants called ‘Succulent,’
Taste is actually a chemical sense which is perceived by the receptor cells of the taste buds present on tongue. Our tongue actually is divided into four different types of papillae which are also called bumps. In each papilla, 50-250 taste buds exist and these taste buds consist of 15 to 20 taste receptor cells
