CELLS, GENETICS, AND EVOLUTION

K-3

SP.14.1 - Many of the structures of living things are made of smaller

structures such as tissues and organs.

SP.14.2.1 - Living things resemble their parents because all parents

pass on their physical characteristics to their offspring.

SP.14.2.2 - All living things interact with and adapt to their environment;

those organisms that are successfully adapted to their environments

are more likely to live to pass on traits to their offspring.

SP.14.3 - Fossils tell us about past life, that life has been on earth for

a very long time, and that more forms of life are extinct than exist today.

SI.14.1 - There is a hierarchy in the organization of living systems, and

at each step the component parts generally contribute to the maintenance

of the organism by performing different functions related to the

conversion and use of energy, protection, and reproduction.

SI.14.2.1 - Within a species there is usually considerable variation in

characteristics, largely determined by the genetic material inherited from

both parents.

SI.14.2.2 - The inheritance of genetic material affects the ability of

organisms to adapt to their changing environments through time.

SI.14.3 - New combinations and changes in the genetic material cause variation

in offspring which have differentiated into the forms of life seen

today; the sequence of forms seen in the fossil record helps us to see the

order in which life has evolved.

SJ.14.l.1 - An organism is an individual with parts (cells, tissues, organs)

that are organized into a functional whole; at every level of organization

these parts have structures that convert and use energy to perform specific

life functions.

SJ.14.l.2 - In order for growth and maintenance of the body to occur, cells

must divide to form new cells which normally are identical to the parent cell.

SJ.14.2 - Genes are made of DNA and determine heredity; genetic factors

contribute to individual variation, which is the raw material of evolution.

SJ.14.3 - Natural selection acts on variation, enabling biological

characteristics better fit to their environment to be more highly represented

genetically in future generations.

SH.14.1 - The chemical and physical bases of metabolism - including the

acquisition, release, and use of energy, mitosis, the removal of wastes,

and cellular differentiation/specialization - are fundamental cellular

processes which are controlled and regulated by interactions of molecules

(nucleic acids, proteins, fats, sugars, enzymes, polysaccharides, lipids,

etc.), atoms, and electrons.

SH.14.2 - DNA and/or RNA is universal to all organisms and, while much is

still to be learned about specific functions, primarily regulates processes

of cell growth and enzyme production that function in the development

of the organism.

SH.14.3 - Evolution unites genetics and molecular biology with earth history

and the physical sciences by showing the continuity of change and the records

of these changes in the rocks and in the structural and biochemical

compositions of all organisms.
