Back 13

stem

Front 14

a point along the stem of a plant atwhich leaves are attached

Back 14

node

a segment of a plant stem between thepoints where leaves are attached

Back 15

internode

Front 16

a structure that has the potential toform a lateral shoot, or branch

Back 16

axillary bud

Front 17

Back 17

lateral shoot

Front 18

a bud at the tip of a plant stem
