Term
Cells
Definition
The smallest unit of life that can survive and reproduce on its own, given informattion in its DNA, energy, and raw materials.
Term

Reproduction, growth, and development
Term
Energy
Definition
The cpacity to do work
Term
Metabolism
Definition
All the enzyme-mediated chemical reactions by which cells acquire and use energy as they build and break down organic molecules.
Term
Producers
Definition
Organism that makes its own food using energy and simple raw materials from the environment.
Term
Consumers
Definition
Organisms that gets energy and carbon by feeding on tissues, wastes, or remains of other organisms.
Term
Heterotroph
Definition
Organism that obtains energy and carbon from organic compounds assembled by other organisms.
Term
Autotroph
Definition
Organism that makes its own food using carbon from inorganic molecules such as CO2, and energy from the environment.
Term
Homeostasis
Definition
Set of processes by which on organism keeps its internal conditions within tolerable ranges.
Term
Growth & Development
Definition
Growth is the increase in the number, size, and volume of cells in multicell species - Development is the multistep process by which the first cell of a new individual becomes a multicelled adult.

Scientific Theory
Definition

Hypothesis that has not been disproven after many years of rigorous testing and is useful at making predictions about other phenomena.

"It is widely accepted and suported by a lot of evidence".

Term
Experimental Group
Definition

A group of objects or individuals that display or are exposed to a vairable under investigation.

"A set of individuals that have a certain characteristic or recieve a certain treatment".

Term
Control Group
Definition
A group of objects or individuals that is identical to the experimental group except for one variable.
Term
DNA
Definition
Deoxyribonucleic Acid; stores and retireves hertiable information in cells.
