XYLEM:

Xylem tissues are the tubular-shaped structure, with the absence of cross walls. This tissue resembles the shape of a star.

It is located in the centre of the vascular bundle.

Xylem fibres are smaller.

They are present in roots, stems and leaves.

These tissues move in a Unidirectional. (only in one direction – upward direction)

PHLOEM:

Phloem tissues are tubular-shaped, elongated, structures with the presence of walls with thin sieve tubes.

It is located on the outer side of the vascular bundle.

Phloem fibres are larger.

They are present in stems and leaves, which later transports and grow in roots, fruits and seeds.
