Hydrocarbons are organic compounds made up of carbon and hydrogen atoms. They are classified into alkanes, alkenes, and alkynes, based on the types of bonds between carbon atoms. Understanding these hydrocarbons is essential in organic chemistry, as they form the basis of fuels, plastics, and many industrial chemicals. Alkanes Alkanes are saturated hydrocarbons because they […]

Every atom forms the building blocks of all matter, making atomic structure one of the most fundamental concepts in Chemistry. The periodic table organises all chemical elements based on their atomic number and mass number, allowing scientists to predict chemical properties and reactions. The atomic structure of an element determines how it behaves in chemical

Acids, bases, and salts are essential substances in chemistry, influencing many aspects of day-to-day life. From the sour taste of citrus fruits like lemons and oranges to the bitter taste of household cleaners, these compounds play a key role in science, industry, and even cooking. In chemistry, an acid is defined as a substance that

Inheritance is the process by which genetic information is passed from one generation to another. It determines the characteristics of a living organism and explains why offspring often look similar to their parents. This process, called inheritance, follows specific patterns, first discovered through Mendel’s laws. At the core of inheritance are genes, which contain instructions

Plant anatomy is the study of the internal structure of plants. It focuses on how different plant organs, such as roots, stems, and leaves, are made up of various cell types and tissues that work together to keep plants alive. In vascular plants, specialised tissues transport water and nutrients. These include xylem and phloem, which

Biological molecules, also known as biomolecules, are the organic compounds essential for life. They form the building blocks of all living organisms, playing a key role in biological processes such as energy production, cell structure, and genetic information storage. These large macromolecules include proteins, carbohydrates, lipids, and nucleic acids, each performing a unique function. Some

Plant reproduction is the process by which plants create new plants to ensure the survival of their species. It occurs through sexual reproduction and asexual reproduction, each with unique advantages. Why Do Plants Reproduce? Plants reproduce to maintain their populations, spread to new areas, and adapt to changing environments. Reproduction in plants allows species to
