The plant cell structure is unique among eukaryotic. Plants cells have a membrane surrounded by nuclei and organelles. Since they can manufacture their food. Chlorophyll gives them a green color. Besides this, it enables plants to use sunlight to convert water and carbon dioxide into sugars and carbohydrates. Plant cells get the protective cell wall
The electromagnetic waves are a form of energy that has both electric and magnetic fields. The electromagnetic spectrum includes all wave frequencies, such as radio, visible lights, and X-Rays. The waves are different from magnetic waves as they can transmit energy and travel through a vacuum. The electromagnetic waves travel with a speed of light
Clouds are the aggregation of innumerable tiny water droplets, ice particles, and dust in the air much above the ground surface. The formation of clouds occurs due to the condensation of water vapor. According to the study, there are more than 100 types of clouds present. These clouds can be grouped into basic types depending
The scientists have discovered that the universe has originated from a single point at a finite time and infinite density. After the initial expansion, the temperature goes down enough to form subatomic particles and atoms. The phenomenon of expansion and formation of the universe is known as the Big Bang theory. The big bang theory
In physics, energy is the capacity for doing work. It may exist in various forms like Kinetic, potential, thermal, electric, radiant, chemical energy, and many other forms. Energy can never be destroyed; it can only be transferred from one body to another. However, all forms of energy are associated with motion. The SI unit of
