- Say to students: “Tell your partner the name of each part of the plant.
Then tell your partner why that part is important to the survival of
the plant.” Students may wish to use Response Card 1 during their
explanation. Alternatively, you may choose to have one student at a
time come up to the image and explain a different plant part. - Be sure that the following information about plant parts has been
reviewed: - The plant’s roots reach down into the soil and grow underground.
The roots take up water and nutrients that are in the soil. - The stem holds the plant up tall and toward the light. Water and
nutrients travel up the stem to other parts of the plant. - Leaves grow out from the stem. Photosynthesis happens at the
leaves. - Many plants have flowers, which are also called blossoms. In the
center or middle of a blossom are many small seeds. - Seeds can grow into new plants.
