Plant Anatomy, Structure and Function

QUESTION 1

Cell Types Concerned with Water Transport in Angiosperms and Their
Differences

In angiosperms, the transport of water is facilitated by specialized xylem cells, primarily
tracheids and vessel elements. These cells form the main conduits for water
movement from roots to other plant parts.

1. Tracheids
o Tracheids are elongated, tube-like cells with tapered ends.
o They possess thick, lignified walls that provide structural support.
o Water moves through them via pits, which allow lateral water transfer
between adjacent tracheids.
o They are present in both gymnosperms and angiosperms but are the
primary water-conducting cells in gymnosperms.
o Water conduction is slower due to the pit membranes acting as
resistance barriers.
2. Vessel Elements
o Vessel elements are shorter and wider than tracheids.
o They are arranged end to end, forming continuous vessels for efficient
water transport.
