(c) Formation of branches
(d) Bears flowers and fruits

Answer 1

Option (b).

Photosynthesis is not a primary function of stem. The process by which leaves prepare their food in the presence of sunlight by using water and carbon dioxide is called photosynthesis. Whereas, conduction of water and minerals from roots to other parts, the formation of branches, bearing flowers and fruits and holding the plant upright are the primary functions of a stem.
