Support, Growth and Stability in Plants

Support

Support system will help plants to stand vertically to obtain sunlight

Terrestrial plant

Terrestrial Plant

Woody plant	Herbal plant
Have secondary xylem woody tissues Examples Thorns Buttress root Prop roots Stilts roots	Depend on turgidity of cells for support Examples Tendrils Twining stems Clasping roots

Aquatic plant

Aquatic Plant

Submerged plant	Floating plant
Fine and thin structure of leaves to reduce water resistance Air space in the stems and leaves to give support Examples Hydrilla Calomba	Fibrous roots trap air bubbles Air spaces in leaves, roots and stems reduces the density and enable the plants to float Examples Water lily Lotus Hyacinth
