Stem: Function, Types, Characteristics, Vascular Bundle, Cross Sectiion.

Question 1

what is the function of the stem

Answer 1

Stems connect the roots to the leaves, helping to transport water, minerals, and sugars to different parts of the plant. Plant stems always have nodes (points of attachments for leaves, roots, and flowers) and internodes (regions between nodes).

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.

Question 4

Stem vascular bundle

Answer 4

A vascular bundle is a part of the transport system in vascular plants. The transport itself happens in vascular tissue, which exists in two forms: xylem and phloem. … In a stem or root this means that the xylem is closer to the centre of the stem or root while the phloem is closer to the exterior.
