Principles of Biology: A Human Approach (BIOL 1150/1151)

Vocabulary flashcards covering key biology concepts and course tools from the BIOL 1150/1151 notes.

Molecules of life

The nucleic acids, proteins, carbohydrates, and lipids that all living things contain.

Cells

The smallest units of life; all cells arise from preexisting cells; organisms can be unicellular or multicellular.

Unicellular

Organisms consisting of a single cell (e.g., bacteria).

Multicellular

Organisms composed of many cells (e.g., plants).

Growth and reproduction

All living things grow and reproduce; reproduction can be sexual or asexual.

Metabolism

All chemical reactions that occur within the cells of living things; organisms use energy and raw materials to carry out metabolism.

Response to environment

Living things respond to their environment.

Homeostasis

The relatively constant and self-correcting internal environment of a living organism.

Adaptation and evolution

Populations have adaptive traits that allow them to survive, reproduce, and eventually evolve.

Seven basic characteristics of all living things

1) Molecules of life, 2) Cells, 3) Growth and reproduction, 4) Metabolism, 5) Response to environment, 6) Homeostasis, 7) Adaptation and evolution.

Levels of biological organization

The hierarchical organization of life from molecules up to ecosystems.

Domains and Kingdoms

Major classifications in biology used to categorize organisms.

Poll Everywhere

An in-class, real-time polling tool used for attendance and questions.

PBL (Problem-Based Learning)

A group-based learning activity used in BIOL 1151 to tackle problems collaboratively.
