Organism Function: BIO100IN

Study guide for Organism Function, (updates in progress)

Properties of Life

The characteristics that distinguish living organisms from non-living matter, including metabolism, growth, reproduction, response to stimuli, and adaptation to the environment.

Hierarchy of Life

The organization of biological entities in increasing complexity, including levels such as cells, tissues, organs, organisms, populations, communities, ecosystems, and the biosphere.

Prokaryotic

organisms are unicellular and lack membrane-bound organelles, including a nucleus. They are typically smaller than eukaryotic cells and include bacteria and archaea.

Eukaryotic

organisms that are characterized by membrane-bound organelles, including a nucleus, and can be unicellular or multicellular, such as plants, animals, fungi, and protozoa.

DNA

a molecule that carries genetic information essential for the growth, development, and reproduction of all living organisms.

Made of Thymine, Cytosine, Adenine, and Guanine, and cross bonded with Hydrogen bonds. It consists of two strands forming a double helix structure.

Three Domains of Life

the classification system that divides all living organisms into three categories: Bacteria, Archaea, and Eukarya. These domains differentiate organisms based on their cellular organization and genetic makeup.

4 Kingdoms of Eukarya

includes Protista, Fungi, Plantae, and Animalia, which represent the diversity of life forms within the Eukarya domain.

Scientific Process

a systematic method for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge through observation, experimentation, and analysis.
