A characteristic that is learned or obtained through experience.
It is not passed on to offspring.
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.
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
The passing of traits from a parent organism to its offspring organism(s).
A characteristic passed from parent to offspring through the process
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
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.
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
A group of cells functioning together to meet a common purpose. Examples
include muscle, bone, and cuticle (the outer covering of a plant).
