B.1.4 Understand and describe that the work of the cell is
carried out by the many different types of molecules it assembles, such as
proteins, lipids, carbohydrates, and nucleic acids.

Molecules and Cells |
|
7.4.5 Explain how food provides the fuel & the building
material for all organisms. |
|
7.4.6 Describe how plants use the energy from light to make
sugars from carbon dioxide & water to produce food that can be used
immediately or stored for later use. |
|
7.4.7 Describe how organisms that eat plants break down the plant
structures to produce the materials & energy that they need to survive,
& in turn, how they are consumed by other organisms. |
|
8.4.5 Explain that energy can be transferred from one form to
another in living things. |
|
8.4.6 Describe how animals get their energy from oxidizing their
food & releasing some of this energy as heat. |
|
B.1.2 Explain that every cell is covered by a membrane that
controls what can enter and leave the cell. Recognize that in all but quite
primitive cells, a complex network of proteins provides organization and
shape. In addition, understand that flagella and/or cilia may allow some
Protista, some Monera, and some animal cells to move. |
|
B.1.3 Know and describe that within the cell are specialized
parts for the transport of materials, energy capture and release, protein
building, waste disposal, information feedback, and movement. In addition to
these basic cellular functions common to all cells, understand that most
cells in multicellular organisms perform some special functions that others
do not. |
|
B.1.6 Show that a living cell is composed mainly of a small
number of chemical elements - carbon, hydrogen, nitrogen, oxygen,
phosphorous, and sulfur. Recognize that carbon can join to other carbon atoms
in chains and rings to form large and complex molecules. |
|
B.1.7 Explain that complex interactions among the different
kinds of molecules in the cell cause distinct cycles of activities, such as
growth and division. Note that cell behavior can also be affected by
molecules from other parts of the organism, such as hormones. |
|
B.1.8 Understand and describe that all growth and development is
a consequence of an increase in cell number, cell size, and/or cell products.
Explain that cellular differentiation results from gene expression and/or
environmental influence. Differentiate between mitosis and meiosis. |
|
B.1.9 Recognize and describe that both living and nonliving
things are composed of compounds, which are themselves made up of elements
joined by energy-containing bonds, such as those in ATP. |
|
B.1.10 Recognize and explain that macromolecules such as lipids
contain high energy bonds as well. |
|
Developmental and
Organismal Biology |
|
B.1.11 Describe that through biogenesis all organisms begin
their life cycles as a single cell and that in multicellular organisms,
successive generations of embryonic cells form by cell division. |
|
B.1.12 Compare and contrast the form and function of prokaryotic
and eukaryotic cells. |
|
B.1.16 Explain how higher levels of organization result from
specific complexing and interactions of smaller units and that their
maintenance requires a constant input of energy as well as new material. |
|
B.1.19 Recognize and describe that metabolism consists of the
production, modification, transport, and exchange of materials that are
required for the maintenance of life. |
Genetics
|
|
B.1.25 Explain that gene mutation in a cell can result in
uncontrolled cell division, called cancer. Also know that exposure of cells
to certain chemicals and radiation increases mutations and thus increases the
chance of cancer. |
|
B.1.26 Demonstrate how the genetic information in DNA molecules
provides instructions for assembling protein molecules and that this is
virtually the same mechanism for all life forms. |
|
Evolution |
|
B.1.30 Understand and explain that molecular evidence
substantiates the anatomical evidence for evolution and provides additional
detail about the sequence in which various lines of descent branched off from
one another. |
|
B.1.34 Explain that evolution builds on what already exists, so
the more variety there is, the more there can be in the future. Recognize,
however, that evolution does not necessitate long-term progress in some set
direction. |
|
Ecology |
|
B.1.37 Explain that the amount of life any environment can support
is limited by the available energy, water, oxygen, and minerals, and by the
ability of ecosystems to recycle the residue of dead organic materials.
Recognize, therefore, that human activities and technology can change the
flow and reduce the fertility of the land. |
|
B.1.44 Describe the flow of matter, nutrients, and energy within
ecosystems. |
