NEET Questions / Botany / Anatomy of Flowering Plants / Xylem
In flowering plants, the main water transporting elements are
Tracheids
Vessels
Fibres
Both (a) and (b)
Conducting tissue for the transport of water and minerals from the roots to the stems and leaves is called
Xylem
Phloem
Parenchyma
Collenchyma
Tracheids
Are the dominant cell types of xylem in angiosperms
Are primarily found in mosses and liverworts
Are responsible for water conduction and support in many land plants
First appeared during Palaeozoic era
In a vascular bundle, if xylem vessels develop in a centripetal fashion, the xylem is likely to be
Mesarch
Centrarch
Endarch
Exarch
Which of the following is true?
Vessels are unicellular and with narrow lumen
Vessels are multicellular and with wide lumen
Tracheids are unicellular and with wide lumen
Tracheids are multicellular and with narrow lumen
The annular and spirally thickened conducting elements generally develop in the protoxylem when the root or stem is
elongating
maturing
differentiating into secondary xylem
undergoing secondary growth
Fusiform initial forms
Vascular rays
Ray parenchyma
Tracheary elements
Primary phloem
I. Tracheids
II. Vessels
III. Fibres
IV. Parenchyma
All the above structures are the attributes of
Xylem
Phloem
Meristem
Vascular tissue
Vessels differ from tracheids
In being living
In being derived from a single cell
In having vertical row of cells with crosswalls dissolved
Because they conduct water
