#9thnewbiology #newsyllabus Emergent properties in biology refer to characteristics or behaviors that arise from the interactions of components within a system, but are not properties of the individual components themselves. These properties become apparent at a higher level of organization within a biological hierarchy. Examples: Cells to Tissues: Cells, when grouped together, form tissues. Tissues, in turn, exhibit properties like contractility (in muscle tissue) that individual cells don't possess. Tissues to Organs: Tissues combine to form organs, and organs have functions (like pumping blood by the heart) that the individual tissues cannot perform. Organs to Organ Systems: Organ systems (like the digestive system) carry out complex functions (digestion, absorption) that individual organs cannot achieve alone. Ecosystems: At a higher level, ecosystems exhibit properties like biodiversity and nutrient cycling, which are not properties of individual organisms.
