Worksheet on Stem System
Worksheet on stem system contains various types of questions.
Remember the important information to the answer the questions given below.
Herb: Plants with soft, juicy and often hollow stem.
Shrub: Small bushy plants having harder stems in which branches grow near the base of the shoot.
Tree: Larger plants with tall pillar-like woody trunks (stem) in which branches may develop at any height.
Creeper: Plants with weak stem, which grow along the ground.
Climber: Plants with weak stem, which grow upward by coiling around any firm object as support.
Shoot system: The portion of a flowering plant,
growing towards the source of light, bearing stem, leaves, buds, flowers and
fruits constitutes the shoot system.
Stem: Rod shaped central axis of the shoot-system.
Nodes: The points on a stem from which leaves grow.
Internode: The portion of a stem in between two nodes.
Apical bud: A tiny outgrowth present at the apical tip of the stem.
Axillary bud: A tiny outgrowth present at the junction of a leaf and a node of a stem.
Terminal bud: A tiny outgrowth present at the apex of each branch.
