  3. c. phloem
  4. d. xylem

Summary Introduction

Introduction: Specialized types of elongated and slender tubes found in the phloem tube are called as sieve tube. Sieve tubes are characteristics of flowering plants. Sieve tubes transport carbohydrates to different parts of the plant.

Reason for correct answer:

Phloem tube that consists of a long distance channel meant for the transportation of prepared food and nutrients from the leaves to different parts of the plant is called as sieve tubes.

Option c. is given as, “phloem”. Sieve tube is the conducting tube of phloem vessel that facilitates the transport of nutrient with the help of adjacent companion cells.

 Hence, the correct answer is option c.

Reasons for incorrect answers:

Option a. is given as “cortex”. The outmost layer of the root and stem of a plant is called as cortex.
