(i) Chlorophyll-containing parenchyma (chlorenchyma) produces food in the process of photosynthesis.

(iii) Lower stems, roots, fruits and seeds contain sugars, proteins and carbohydrates.
(iv) Helps in plant wound healing and regeneration.
(v) Provides strength to leaves and stems.
(vi) Stamens keep the plant upright by hydrostatic pressure.
(vii) Propagation by asexual roots and shoots.
