Unpacked Content
3.L.2.1 Students know the names and
functions of major plant parts (roots, leaves,
stem, flowers). Students know that plants
have special parts that perform special
functions in order for the plant to survive.
3.L.2.2 Students know that how well plants
grow and survive is determined by a
Science For All Americans
(Content knowledge for adults.)
Every species is linked, directly or indirectly, with a multitude of
others in an ecosystem. Plants provide food, shelter, and nesting
sites for other organisms. For their part, many plants depend upon
animals for help in reproduction (bees pollinate flowers, for
instance) and for certain nutrients (such as minerals in animal

combination of environmental conditions.
For example, drought conditions will tend to
diminish plant health and growth.
3.L.2.3 Students know the distinct stages of
the life cycle of seed plants (seed,
germination, seedling, adult).
3.L.2.4 Students know that different soils
possess different textures and capacities for
the retention of water and nutrients.
Students know that soil consists of different
components. Students know that these
characteristics of soil influence the growth
and survival of plants.
waste products).
Plants and animals reshape the landscape in many ways. The
composition and texture of the soil, and consequently its fertility
and resistance to erosion, are greatly influenced by plant roots
and debris, bacteria, and fungi that add organic material to the
soil, and by insects, worms, and burrowing animals that break it
up. The presence of life has also altered the earth's atmosphere.
Plants remove carbon dioxide from the air, use the carbon for
synthesizing sugars, and release oxygen. This process is
responsible for the oxygen in our air today.
Insects and various other
organisms depend on dead
plant and animal material for
food.
Organisms interact with one
another in various ways
besides providing food.
Many plants depend on
animals for carrying their
pollen to other plants or for
dispersing their seeds.
Over the whole earth,
organisms are growing, dying,
decaying, and new organisms
are being produced by the old
ones.
Soil is made partly from
weathered rock, partly from
plant remains—and also
contains many living
organisms.

WRITING PROMPTS
Explain the factors (conditions) that plants need to grow. Describe why each of these factors (conditions) is important in plant development.
