A. xylem and phloem

B. phloem and tracheid

C. phloem and xylem

D. xylem and tracheid

QUICK ANSWER…

A

DETAILS…  

Plants absorb and transport water from the roots via a vascular tissue called xylem. They also transport food produced by photosynthesis to storage via a vascular tissue called phloem.

Now for the right answer to the above question:

  1. Respectively, xylem and phloem transports water and synthesized food. So, A is correct.
  2. Phloem and tracheid not respectively the answer. Besides, tracheids are primitive components of xylem, they are water conducting cells and not tissues. B is incorrect.
  3. Observe the presence of the word ‘respective’ in the question. This means the answers should correspond to the appropriate things they transport. So, C is incorrect.
  4. D is also incorrect; xylem and tracheid not respectively the answer.

QUICK ADVICE…

You may please note that:

  • The term respectively should be understood to mean the answers should correspond to the prior arrangement; that is, first question for first answer, and second question for second answer.
  • Tracheids are cells and not tissues; they are an integral component of the xylem tissue which aids in water transportation.
