Atoms
Basic building blocks of matter.
 Make up everything.
 Bond with other atoms according to
specific patterns and thereby make:

Molecules and Macromolecules
Molecules!
 Molecules = combinations of atoms.

 Specific
atoms.

Molecules combine in long chains to make
macromolecules.
 Same

properties, different than those of single
properties as their respective molecules.
Example: carbs, lipids, proteins, nucleic acids
Organelles and Cells
Macromolecules work together to form
organelles.
 Organelles have specific functions in cells.

 Example:

Cells are basic building blocks of life.
 (They

nucleus, membrane, GOLGI!!!!!
carry out all functions of life.)
Different kinds of cells (with different
specialties) group together to form:
Tissues
Tissues! (not the kind with which you blow
your nose)
 Composed of cells that have common
functions.

 Example:

brain tissue, stomach tissue
Tissues make up:
Organs and Organ Systems
Organs!
 Organs are complex organizations of
tissues that carry out very specific tasks.

 Not
in surplus. (You only have 1 heart, 1
brain, 1 liver, etc.)

Organs make up organ systems.
 Organ
systems are groups of organs with
similar tasks. (Stomach and small intestine
help make up digestive system.)
Organism

An organism is a living thing.
 Has
all characteristics of life.
Each organism is made up of organ
systems working together.
 Generally, it survives, unlike just a piece of
lung on a table.
