The study of life, encompassing living and non-living aspects.

Study of organism structures and parts, both macroscopic and microscopic.

Study of microscopic tissues using optical instruments.

Study of living organisms' functions and processes.

Study of inherited traits and variations.

Study of biology at the molecular level (e.g., DNA, RNA).

Study of human anatomy and processes like growth, nutrition, and reproduction.

Development of complex species from simpler ones through gradual change.

A cell is the basic unit of structure and function in living organisms. It carries out essential life processes like metabolism and reproduction.

Organelles are specialized membrane-bound structures inside cells that perform specific functions. They are like mini-organs within a cell.

A group of individuals of the same species living in the same area, capable of interbreeding.

All the different populations of species that interact within a specific ecosystem.

A community of living organisms interacting with their physical environment, including the water, soil, sunlight, etc.

The hierarchical arrangement of structures in living organisms, from atoms to molecules, cells, tissues, organs, organ systems, and the complete organism.

Two or more atoms joined together.

The basic functional unit of an organism. Can be single-celled or part of a multicellular organism.

Groups of similar cells performing a specific function.

A structure composed of different tissue types, functioning together.

A group of organs working together to perform a major function in the organism.

The maintenance of a stable internal environment in an organism.

An organism made up of only one single cell.

An organism composed of many cells working together.

A single-celled organism lacking a nucleus and membrane-bound organelles. It's simpler in structure.

An organism with a nucleus and membrane-bound organelles, more complex in structure.

Single-celled organisms without a nucleus. They are found in diverse environments.

Single-celled organisms without a nucleus, often found in extreme environments like hot springs or salty lakes.

Organisms with cells containing a nucleus and internal compartments. Includes animals, plants, fungi, and protists.

A two-word naming system used for all organisms, with the first word representing the genus and the second representing the species.

The scientific name for modern humans, distinguishing us from earlier human species.

All the changes that occur in an organism from fertilization until death, including growth, childhood, adolescence, adulthood, and repair after injury.

An increase in size and often number of cells. It's a part of development.

Maintaining a stable internal environment in an organism, like body temperature or blood pressure.

Living things react to external factors using various mechanisms. In humans, the nervous and musculoskeletal systems are key for movement and response.

The body uses self-regulating mechanisms to maintain a stable internal environment.

Organisms with beneficial traits for their environment survive and reproduce better than those without those traits.

A characteristic that helps an organism survive and reproduce in its specific environment.

Over time, populations change due to natural selection, leading to the development of new traits and species.
