Correct Answer: B
Solution :
Trachieds (Sanio, 1863), are elongated dead cells having lignified walls with lumen which take part in the conduction of water. In the given figure the following types of trachieds are present. A-Annular (Ring like bands of thickenings) B-Spiral (Spiral or helical bands of thickenings) C-Scalarifrom (Transverse plates of thickenings) D-Reticulate (Reticulum or network of thickenings). E-Pitted with border (narrow mouth and flask shaped chamber) F-Pitted, simple (uniform width)You need to login to perform this action.
