• living things are diverse organism that inhabit our planet and interact with the surrounding environment.


  Living things can be found in various ecosystems, from the depths of ocean to the highest mountainstop.
• Multicellular organisms consist of multiple cells that work to form tissues, organs, and organ systems.
• Multicellular organisms display higher complexity, specialization of cells, and division of labor among different cell types.
• CELLULAR ORGANIZATION: Living things are composed of one or more cells which are the basic structural and functional units of life.
• CELLULAR ORGANIZATION: Cells have specialized structures and

  organelles that carry out specific functions.
• Metabolism refers to the sum of all chemical reactions occurring within an organism.
• Living things acquire and transform energy, using it to carry out vital functions such as growth, repair, and reproduction.
• Homeostasis is the ability of living things to maintain a stable internal environment despite external fluctuations.
• HOMEOSTASIS: Organisms regulate their internal conditions through feedback mechanisms to ensure optimal functioning.
• Scientists throughout history have made significant contributions to our understanding of living things and their interactions with the environment. Prominent figures such as Carl Linnaeus, Charles Darwin, and Gregor Mendel laid the foundations of taxonomy, evolution, and genetics, respectively.
