    Study Notes

    Characteristics of Life

    • All living things are composed of similar chemical elements, reflecting the scientific principle of unity among living organisms.
    • Living things often function and behave in ways strange to humans, emphasizing their unique characteristics and behaviors.
    • The characteristic that defines life is the ability to function and behave in unique ways.

    Diversity of Living Things

    • The diversity of living things is due to evolutionary forces.
    • The reason behind the diversity of living things is the variation in the evolutionary forces that act upon them.

    Cell Structure

    • The smallest structural and functional unit of all living things is the cell.
    • Unicellular organisms are microscopic and include Paramecium and Bacteria.
    • Paramecium is distinguished from Bacteria by its characteristics.

    Classification of Organisms

    • The science of classifying organisms into categories is known as taxonomy.
    • The sequence of classification categories from larger to smaller is: domain, kingdom, phylum, class, order, family, genus, and species.
    • A two-part scientific name is called a binomial name.
    • The most closely related category in the sequence of classification categories is species.

    Multicellular Organisms

    • Multicellular organisms have organs, organ systems, and tissues that are not found in unicellular organisms.

    Nervous System

    • The nervous system includes the brain, spinal cord, and nerves.

    Ecosystem

    • The biosphere ecosystem is a giant web of life that is spread around the globe, highlighting the interdependence of living things.
    • The existence of living things depends on one another, emphasizing their interconnectedness.

    Plants

    • Plants are photosynthetic and make their own food, distinguishing them from other organisms.
    • This characteristic of plants allows them to produce their own food through photosynthesis.
