Zorluk: KolayTransport Mechanisms in Plants

During photosynthesis in vascular plants, synthesized organic nutrients such as sucrose are distributed from the leaves to roots, fruits, and growing points. Which plant tissue is primarily responsible for carrying out this transport process?

  1. PhloemCevap
  2. B
    Xylem
  3. C
    Cortex
  4. D
    Sclerenchyma

Cevap

Phloem
Phloem is the specialized vascular tissue responsible for translocation, moving sugars and organic compounds manufactured in leaves to non-photosynthetic organs such as roots, stems, and fruits.

Adım Adım Çözüm

1
Identify the type of substance being transported in the plant scenario
The scenario describes the transport of manufactured organic nutrients (sucrose) from photosynthetic leaves to other plant organs.
Distinguishing between organic solutes and inorganic raw materials determines the specific vascular tissue responsible.
2
Match the transport material with the appropriate vascular tissue
Phloem tissue (comprising sieve tube elements and companion cells) is specialized for translocating organic solutes from source to sink.
Xylem transports water and dissolved minerals, while phloem translocates photosynthates.
