Question

Describe the Evolutionary significance of secondary xylem parenchyma.

Answer 1

The evolutionary significance of secondary xylem parenchyma.

Parenchyma cells in the secondary xylem of woody plants provide a vital response to xylem infection and mechanical damage and they play a critical role in the plant defense systems.The living parenchyma cells play a critical role in all of the four walls that the model comprises. these cells are associated with an array of functions,from capacitance, to storage, and long-distance water transport.

Answer 2

Parenchyma cells are the 'secondary xylem' of woody plants.

EXPLANATION:

These cells play a vital role in response to 'xylem infection' and any mechanical damage. They also act as a defense mechanism in plants. The 'living parenchyma cells' play a important role in all the four wall model.

These cells are associated with an array of functions, from capacitance and storage. These cells also transport water to different parts of the plants when xylem is unable to function.
