Title: Unit 3, Lesson 7 Stem Structures and Functions


1
Unit 3, Lesson 7Stem Structures and Functions
2
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

10
  • 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
