1) Cellular Organization: All living things are made up of cells, which are the basic structural and functional units of life. Whether an organism is composed of a single cell (unicellular) or multiple cells (multicellular), cells are essential for carrying out vital processes such as metabolism, reproduction, and response to stimuli.
2) Metabolism: Living things have the ability to obtain and utilize energy through metabolic processes. They can consume and break down organic molecules to release energy in the form of ATP (adenosine triphosphate), which is used to fuel various cellular activities. Metabolism also includes the synthesis of complex molecules from simpler ones, enabling growth, repair, and maintenance of the organism.
3) Homeostasis: Living organisms exhibit homeostasis, which refers to the maintenance of stable internal conditions necessary for their survival and proper functioning. This involves regulating factors such as temperature, pH levels, nutrient balance, and water content within their cells and body systems. Homeostasis ensures that an organism can adapt to changes in its external environment and maintain equilibrium to support its overall health and well-being.
