Structural Level Flashcards
(21 cards)
The simplest level which includes tiny building blocks such as atoms.
Chemical level
the smallest functional units of life.
Cells
groups of macro-molecules used to carry out a specific function in the cell.
Organelles
the basic units of structure and function for living things.
Cells
groups of cells functioning together.
Tissues
form organs that have specialized functions.
Group of Tissues
function together as an organ system.
Group of Organs
systems functioning together, to make up an organism.
The Body Organs
Molecules form cells. Cells form tissues, and tissues form organs. Organs that fulfill related functions are called organ systems. An organism is made up of interconnected organ systems.

have long been recognized as the simplest units of living matter that can maintain life and reproduce themselves.
Cells
An organ system is a group of organs that work together to perform one or more functions. Each organ has a specialized role in a body, and is made up of distinct tissues
