Characteristics of Life Flashcards
This simply means that living things are made up of cells.
CELLULAR ORGANIZATION
The most basic unit of life
CELLS
How are new cells are formed?
Only by the division of previously existing
cells.
The concept expressed in “Cell Theory” that was formulated by?
Robert Hooke, Matthias Schleiden, Theodor Schwann and others.
If something is alive, it must be capable of producing
REPRODUCTION
Is the process by which individuals are
reproduced by asexual or sexual reproduction
REPRODUCTION
____ lifeforms, such as humans who reproduce sexually
Multicellular
____ lifeforms, like bacteria that reproduces
asexually
Unicellular
This is essentially a collection of chemical reactions occurring within the body or cell.
METABOLISM
occur continuously in every living organism, and they must be carefully regulated to maintain the next characteristics
Metabolic processes
These reactions in Metabolism vary in form and function, but promote processes such as:
Protein synthesis, Cell division, Chemical digestion, Energy transformation
Sum of all the chemical activities of the organism
METABOLISM
An appropriate or a balanced internal environment
HOMEOSTASIS
Maintaining _____ is a vital characteristic of life
HOMEOSTASIS
Term used to describe maintaining a stable internal environment
HOMEOSTASIS
Our genetic information can be passed from one generation to another
HEREDITY
All forms of life respond to _____
STIMULI
Is the physical or chemical changes in the internal or external environment.
STIMULI
Responding to stimuli involves ____, though not always ______ (moving from one place to another)
movement; locomotion
Involves an increase in the size of individual cells of an organism, or in the number of cells, or in both.
Biological Growth
May be uniformed in the various forms of an
organism or it may be grater in some parts than in others
GROWTH
_______ includes of the changes that take place during an organism’s life.
DEVELOPMENT
The _____ and _____ that develop are explicitly adapted to the functions the organism must perform.
structure and body forms
This is a judgement or changes in behavior, physiology, and structure of an organism, to become more suited to the environment.
ADAPTATION THROUGH EVOLUTION
The ability of a population to evolve changes overtime; adapt to its environment quips it to survive in a changing world
Theory of Evolution by Natural Selection
Has become the most important unifying concept of biology
Theory of Evolution by Natural Selection
Characteristics that enhance an organism’s ability to survive in a particular environment
ADAPTATION
Every biologically successful organism is a complex collection of _________ with risk through evolutionary processes
coordinated adaptations
