B) Primary xylem and phloem
C) Secondary xylem only
D) Primary phloem and secondary xylem

Answer 1

Answer:

Plants are classified based on many criteria, and one such classification is the presence or absence of a vascular system. Essentially, a vascular plant has specialized features that help it to absorb water and minerals from the soil. These include special tissues such as xylem and phloem.

Xylem and Phloem are two different types of vascular tissues which are mainly involved in the transportation process. These tissues form a vascular bundle and these work together as a unit. The movement of xylem is unidirectional, while, the movement of phloem is bidirectional.

Difference between Xylem and Phloem

Xylem Tissues

Xylem is one of the important tissues of the vascular system of plants. The main activity of this tissue is to transport minerals and water from roots and carry them to other parts of the plants. It has two separate chambers tracheids and vessels for transporting minerals and water. The term xylem is derived from the Greek word – ξύλον (xylon), meaning wood.

Phloem Tissues

Phloem is also important as the xylem tissues for the vascular system of plants. The main activity of this tissue is to transport nutrients and food from leaves to other growing parts of plants. The term phloem is derived from the
