Introduction to the concept of biological systems and emergent properties.

• Living beings are organized in a series of categories that help study their structure, function, and behavior.
• Biological systems are made of interconnected parts forming complex organizations with unique characteristics.
• Emergent properties arise from the sum of the characteristics of the parts of a system.

Description of atoms, molecules, and their significance in living beings.

• All living beings are composed of chemical compounds made up of molecules and atoms.
• Molecules have different properties from their individual atoms, exemplified by water (H₂O).
• Macromolecules such as nucleic acids, proteins, lipids, and carbohydrates are crucial for life.

The cell as the fundamental unit of life and its types.

• Cells are the smallest living structures, existing as unicellular or multicellular organisms.
• They contain organelles for specific functions and are categorized as prokaryotic or eukaryotic.
• Eukaryotic cells have internal organization with organelles, unlike prokaryotic cells.

The formation and role of tissues in multicellular organisms.

• Tissues are formed when cells associate and perform special functions, such as muscles and nerves in animals.
• Plant tissues include the epidermis and vascular tissue, essential for protection and nutrient transport.
• Tissues carry out specialized functions that individual cells cannot perform alone.

Organs and systems are complex structures that serve specific functions in living organisms.

• Organs are made up of tissues that work together to perform specific functions in an organism.
• Examples of organs include the heart and lungs in animals, and roots and leaves in plants.
• An apparatus or system is formed by the association of different organs, like the circulatory and musculoskeletal systems.

Exploration of organisms as an assembly of systems and organs, and populations as groups of the same species.

• An organism is a closely related assembly of systems, tissues, and cells that function together.
• Organisms are capable of feeding, growing, reproducing, interacting with the environment, and dying.
• Populations consist of individuals of the same species living in the same area and capable of reproduction.

Communities form from different species coexisting, and ecosystems involve biotic and abiotic factors.

• Communities are formed by populations of different species interacting within a geographic area.
• Ecosystems are made up of communities and are influenced by environmental factors such as water and temperature.
• The biosphere encompasses all ecosystems and living habitats on Earth.
