Difficulty: EasyPlant Biology and Photosynthesis

In vascular plants, specialized internal systems distribute nutrients and hydration throughout the organism. Which tissue carries water and dissolved minerals upward from the roots to the leaves?

  1. A
    Phloem
  2. XylemAnswer
  3. C
    Epidermis
  4. D
    Cuticle

Answer

Xylem is the vascular tissue responsible for conducting water and dissolved minerals upward from the roots to the leaves.
Xylem consists of specialized tubular cells (such as vessel elements and tracheids) that create a continuous conduit for transporting water and dissolved soil minerals upward from the root system to aerial plant structures via transpirational pull and root pressure.

Step-by-Step Solution

1
Identify the primary substance being transported and the direction of flow described in the problem.
The process involves upward transport of water and dissolved minerals starting from the root system.
Plant transport systems are divided by function between water-conducting and sugar-conducting tissues.
2
Distinguish between the primary vascular tissues in plants.
Xylem conducts water and minerals upward, whereas phloem distributes synthesized sugars throughout the plant.
Matching the specific physiological role to the correct anatomical structure confirms xylem as the answer.
