1. What are the major functions of the stem?

• After collecting your stem functions in the
  Memory Game and checking with your teacher, glue
  them here.

3
Functions of stems (to be cut apart, one sheet
per page, by teacher before class)

• To transport water from the roots.

To transport minerals from the roots.
To transport food from the leaves.
To support the plant so it can reach sulight.
To support the leaves.

• The scar left on a twig when a leaf falls.
• Indicates the amount growth in one year.
• Tissue in the vascular system of plants that move
  dissolved sugars and other products of
  photosynthesis from the leaves to other regions
  of the plant. Cells of the vascular system in
  plants that transport food from leaves to other
  areas of the plant.
• Flower bud
• The stem region of a plant where one or more
  leaves attach. Where leaves are attached to
  stems.
• Node
• Space between nodes

9

• Tissue in the vascular system of plants that
  moves water and dissolved nutrients from the
  roots to the leaves. Plant tissue type that
  conducts water and nutrients from the roots to
  the leaves.
• A corky spot on the bark which originally
  permitted air to enter the twig.
• Leaf scar
• Terminal bud
• Lenticels
• Xylem
• Xylem
• Phloem
• Phloem
• Pith
• Cambium

• A lateral meristem in plants. Types include
  vascular, cork, and intercalary.
• Leaves that cover the outside of the bud.
• Central area in plant stems, largely composed of
  parenchyma tissue modified for storage.
• Located at the end of the plant shoot.
• Axillary or lateral bud
• Born in the axil (where the leaf meets the stem)
  of a stem.
• Internode
• Growth Rings
