What are the characteristics of a stem?
Characteristics of StemsThe stem is an ascending axis of the plant and develops from the plumule and epicotyl of the embryo.It is generally erect and grows away from the soil towards the light. … The growing apex of stem bears a terminal bud for growth in length.More items…
What is the base of a tree trunk called?
The lower trunk is where trunk tissue meets with root tissue.
Is a tree trunk a stem?
In botany, the trunk (or bole) is the stem and main wooden axis of a tree, which is an important feature in tree identification, and which often differs markedly from the bottom of the trunk to the top, depending on the species.

What is STEM lesson plan?
STEM lessons are guided by the engineering design process. In this process, students define problems, conduct background research, develop multiple ideas for solutions, develop and create a prototype, and then test, evaluate, and redesign them.
