Know and Use.

Acquired trait

A characteristic that is learned or obtained through experience. It is not passed on to offspring.

Asexual Reproduction

Reproduction involving only one parent. No genetic information is exchanged. The offspring generally looks similar to the parent organism.


The basic unit of all living things.

Cell Wall

The outermost part of a plant cell found outside the cell membrane. It is quite rigid and helps maintain the shape of the plant.


The green structure inside a plant cell that changes sunlight into usable energy for the plant.


The material between a cell membrane and the nucleus. It includes the various organelles which help a cell to function.


The process of matter spreading out evenly from its source. An example of diffusion is when perfume is sprayed and eventually is smelled throughout a room.


The passing of traits from a parent organism to its offspring organism(s).

Inherited trait

A characteristic passed from parent to offspring through the process of genetics.


The outer portion of a cell. It surrounds the cell and helps keep the contents inside. The membrane also controls what enters or leaves a cell.


The control center of a cell. It contains genetic information that regulates how a cell functions.


Organisms that result from the process of reproduction. These organisms share genetic similarities with their parents.


The part of an organism made up of tissues that perform a specific job. Examples include skin, heart, lungs, stems, leaves, and roots.


Any living thing. Some may exist as a single cell (unicellular) but most are made of many cells (multicellular) such as plants and animals.


A special form of diffusion that occurs in liquids. One liquid spreads evenly within another liquid.

Sexual Reproduction

Reproduction involving two parents. Genetic information is exchanged. The offspring usually has some observable differences from either parent.


A group of organs that work together to perform a common function. Examples of systems include skeletal, nervous and vascular (tubes in plants).


A group of cells functioning together to meet a common purpose. Examples include muscle, bone, and cuticle (the outer covering of a plant).
