Supporting tissues in plants have several functions, including:

• Structural support: Supporting tissues provide the framework and support the structure of the plant, holding up leaves, flowers, and buds. 

• Transportation: Supporting tissues transport water, nutrients, and assimilates throughout the plant. 

• Protection: The strength of supporting tissues protects the plant from enemies. For example, the hard shell of many seeds prevents animals from chewing them to pieces or puncturing them. 

• Flexibility: Supporting tissues give the plant flexibility and resilience, allowing it to bend without breaking.
