While plant cells are similar to animal cells in many ways, it is the key differences between them that make plants so different from animals. In this article, we have covered the key differences and similarities between a plant and an animal cell.
Carbon is the most vital element of life. All living things are made up of compounds of carbon. Atoms in a molecule are held together by chemical bonds. The diversity of matter we see around us is thanks to the arrangement of molecules in different combinations.
Not to long from now, our computers may become a hundred times faster thanks to something called graphene. Scientists are thinking about replacing today’s silicon chip in today’s electronics with graphene chip. What makes graphene so awesome? Graphene is a single layer of graphite. It is only one atom thin. This arrangement is what gives graphene awesome properties that scientists are now busy exploring.
All animals, including you and I, are made of the same basic building block called the animal cell. Animal cells are generally smaller than plant cells and lack a cell wall and chloroplasts; these are organelles pertinent to plant cells.
Life on this planet is dependent on the availability of water. Scientists are always looking for evidence of water in other worlds because water is the solvent that drives life here on earth. Water exists naturally in solid, liquid and gaseous forms. It is the only substance on our planet that exists naturally in all three states of matter. A single water molecule is made up of two hydrogen atoms (H) and one oxygen atom (O). The hydrogen atoms each share a pair of election with the oxygen atom...
Biomolecules are the ingredients necessary for life. They are the building blocks of all living things on earth and are essential for their survival. Biomolecules function as essential energy sources, they provide the means to store energy, they contain instructions that living things need for healing, growth and reproduction. There are four main classes of biomolecules; Carbohydrates, Lipids, Proteins and Nucleic Acids.
