(ii) List any two characters and functions of this tissues.

(ii) Characteristics:
(a) It consists of living cells (b) The cell wall is generally unevenly thickened.
Functions:
(a) It provides tensile strength to various plant organs, hence, primarily mechanical in function.
(b) Collenchyma cells also perform photosynthesis.
