    Study Notes

    Chemical Reactions and Processes

    • Rust is chemically known as iron(III) oxide, represented as Fe₂O₃.
    • The process of photosynthesis produces oxygen gas (O₂) as a byproduct, occurring in plants, algae, and some bacteria.

    Fundamental Compounds

    • Water is comprised of two hydrogen atoms and one oxygen atom, with the chemical formula H₂O.

    Biological Functions

    • Reproduction in living organisms is termed reproduction and encompasses both asexual and sexual methods to produce offspring.
    • Photosynthesis occurs mainly in the chloroplasts of plant cells, with chlorophyll being the pigment that captures light energy.
    • The respiratory system's primary function is the exchange of gases, facilitating the intake of oxygen (O₂) and the removal of carbon dioxide (CO₂) from the body.
