    Study Notes

    Carbon Chemistry

    • Carbon atoms form covalent bonds with each other due to their four valence electrons, allowing them to create stable structures through single, double, or triple bonds.
    • The ability to form chains and rings leads to an immense variety of carbon-based compounds.

    Organic Chemistry

    • The branch of chemistry that explores compounds formed by carbon and elements such as hydrogen, oxygen, and nitrogen is called organic chemistry.
    • Organic chemistry focuses on the structure, properties, composition, reactions, and synthesis of organic compounds.

    IUPAC System

    • The International Union of Pure and Applied Chemistry (IUPAC) system is utilized for naming organic compounds consistently and systematically, ensuring clarity in communication among chemists.

    Purification Techniques

    • A common technique for the purification of organic compounds is chromatography, allowing separation and identification of various components in a mixture.

    Plant Responses

    • The part of the plant that is negatively phototropic (growing away from light) and aerotropic (growing toward air) is the root system.

    Psammophytes Habitat

    • Psammophytes are typically found in sandy habitats, such as coastal dunes or deserts, where they exhibit specialized adaptations for survival.

    Shoot System Function

    • The primary function of the shoot system in angiosperms includes supporting leaves, flowers, and fruits, facilitating photosynthesis, reproduction, and nutrient transport.

    Aquatic Angiosperms

    • Aquatic angiospermic plants, such as water lilies and lotus, are adapted to living in water environments, exhibiting floating leaves and submerged roots.

    Primary Roots in Angiosperms

    • The primary roots of angiosperms are responsible for anchoring the plant, absorbing water and nutrients, and sometimes storing energy in the form of starches.
