• Not Limited to certain regions

• Localised and dividing cells

• Growing in volume

Component of xylem helps in lateral conduction of water

• Tracheids

• Vessels and tracheids

• Xylem parenchyma

• Xylem fibers

Function of xylem

• Provide mechanical strength

• Conduction of water

• Connection of food

• Both 1and 2

• Sclerenchyma

• Chlorenchyma

• Parenchyma

• Collenchyma

Which is not a function of epidermis

• Protection from adverse condition

• Gaseous exchange

• Conduction of water

• Transpiration

The flexibility in plants is due to a tissue called
