KEY CONCEPT
The cell is the basic unit of living things.
All living things are made up of one or more cells.
Organisms share the following characteristics:
• organization
• ability to grow and develop
• ability to respond
• ability to reproduce

7.1.b Students know the characteristics that
distinguish plant cells from animal cells, including
chloroplasts and cell walls.
nucleus
7.1.c Students know the nucleus is the repository for
genetic information in plant and animal cells.
organelle
7.1.d Students know that mitochondria liberate energy
for the work that cells do and that chloroplasts capture
sunlight energy for photosynthesis.

7.5.a Students know plants and animals have levels of
organization for structure and function, including cells,
tissues, organs, organ systems, and the whole
organism.
7.5.b Students know organ systems function because
of the contributions of individual organs, tissues, and
cells. The failure of any part can affect the entire
system.

Cells can perform specialized functions.
• The single cell of a unicellular organism does all
that is necessary for the organism to survive.
• A multicellular organism is a community of
specialized cells.
• Scientific models make it easier to understand cells.
