    Study Notes

    Understanding the Building Blocks of Life

    At the core of biology lie three fundamental aspects that drive our understanding of life: cells, genetics, and evolution.

    Cells: The Basic Unit of Life

    Cells are the smallest structural unit of living beings. They are surrounded by a membrane and function as individual units capable of performing various vital processes like metabolism and reproduction. We distinguish between prokaryotic and eukaryotic cells—the former lack a nucleus, while the latter have a distinct nucleus containing genetic material.

    Genetics: The Language of Life

    Genetics deals with heredity and variation in living organisms. At its heart lies the notion of genes and DNA. DNA carries the blueprint of life and determines traits inherited from parents. Through genetic mutations and natural selection, new variations arise over generations, leading to adaptation and evolution.

    Evolution: Change Over Time

    Evolution refers to changes in the genetic makeup of populations across generations. Natural selection plays a central role in evolution by favoring advantageous traits over disadvantageous ones, increasing the chance of survival for individuals possessing those traits. Over time, these differences accumulate, eventually resulting in the emergence of new species through speciation.

    These interconnected components of biology create a fascinating tapestry of life on Earth, where cells serve as building blocks, genetic codes carry instruction sets, and evolution shapes creatures across millennia.
