What is Life Flashcards
What is the study of life?
Biology
What is the term used to help you remember all of the
characteristics of life?
Dr.rcop
Cellular organization, the ability to reproduce, growth & development, energy use, homeostasis, response to their environment, and the ability to adapt.
There are 6 characteristics of life.
What are the 6 characteristics of life?
Dr.rcop
Determines the traits of all living
organisms
What are the 2 main cell categories?
prokaryotic and eukaryotic
Where is DNA stored?
cell nucleus
DNA is inherited from an organism’s
parent(s).
What does “prokaryotic” mean?
organisms whose cells lack a nucleus and other organelles
eukaryotic
“True” nucleus
Prokaryotic cells have a nucleus. True or False
False
DNA floats in the cytoplasm of this type
of cell.
DNA is housed in the nucleus of this
type of cell.
What are examples of organisms that are made up of
prokaryotic cells?
bacteria and archaea.
What are 2 types of cells both eukaryotic cells?
plant and animal
Prokaryotic cells are the most complex cells. True or False
False
Eukaryotic cells evolved from prokaryotic cells. True or False
True
Which category of cells makes up unicellular organisms
((Prokaryote, Eukaryote, or both)?
both
Reproduction
What are the two categories of reproducers?
Asexual & Sexual
Which type of reproducer is made up of only one parent?
Asexual
Offspring from which type of reproducer develops from the
combination of receiving 50% chromosomes from a female
parent and 50% chromosomes from a male parent?
Sexual
Which type of reproduction requires 2 parents from each
gender (1 male, 1 female) to create offspring?
Sexual
How do offspring develop from asexual reproductions?
genetically identical to the parent because the offspring are all clones of the original parent
Cells
The building blocks of all living things.
What are the 3 rules of Cell Theory?
All living organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells.
What does autotrophic mean?
An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals
Any organism that consumes other
organisms for food in order to create
energy for the body.
Define the characteristic: Obtains energy
using the light and chemical energy of the environment or consuming other living things.
2 ways different organisms can obtain energy
Autotrophism and heterotrophism
Plants are heterotrophic. True or False
true
What type of organisms are heterotrophic?
Dogs, birds, fish, and humans
Define biotic
a living organism that shapes its environment
Define abiotic
The increase of size and mass of an
organism.
Define development
The ability for any organism to respond
to internal or external stimulus.
The internal balance of an organism.
Define adaptations
a modification of an organism or its parts that makes it more fit for existence
The classroom thermostat is broken and the room is very hot
and stuffy. How will your body internally respond to this
external stimulus?
Your day has been busy and you forgot to have breakfast
and then missed lunch. How will your body internally alert
you that it requires nourishment (food)?
What are membrane-bound organelles?
ellular structures that are bound by a biological membrane
Which category of cells does not contain membrane-bound
organelles?
Prokaryotic cells
All categories of cells contain DNA. True or False
True
Which category of cells can create unicellular and
multicellular organisms?
Eukaryotic organisms
What is the formula for total magnification when looking
through a microscope?
Multiply the power of the ocular lens by
the power of the objective being used.
What is the total magnification if the ocular lens is 10x and
the objective being used in 40x?
400
