The respective tissues that transport water and manufactured food in plants are…
A. xylem and phloem
B. phloem and tracheid
C. phloem and xylem
D. xylem and tracheid
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:
- Respectively, xylem and phloem transports water and synthesized food. So, A is correct.
- 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.
- 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.
- D is also incorrect; xylem and tracheid not respectively the answer.
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.
