Which of the following plant tissues is NOT a type of simple tissue?

निम्नलिखित में से कौन-सा पादप ऊतक (Plant Tissue) सरल ऊतक (Simple Tissue) का प्रकार नहीं है?

Options / विकल्प

A. Collenchyma
कोलेन्काइमा

B. Sclerenchyma
स्क्लेरेंकाइमा

C. Xylem
जाइलम

D. Parenchyma
पैरेंकाइमा


Correct Answer / सही उत्तर

✅ C. Xylem (जाइलम)


Detailed Explanation / विस्तृत व्याख्या

Hindi

जाइलम (Xylem) एक जटिल स्थायी ऊतक (Complex Permanent Tissue) है, क्योंकि यह एक से अधिक प्रकार की कोशिकाओं से मिलकर बना होता है जो मिलकर एक विशेष कार्य करती हैं।

जाइलम के प्रमुख घटक हैं:

  • ट्रेकिड्स (Tracheids)
  • वाहिकाएँ (Vessels)
  • जाइलम पैरेंकाइमा (Xylem Parenchyma)
  • जाइलम फाइबर (Xylem Fibres)

इसका मुख्य कार्य जड़ों से पौधे के अन्य भागों तक जल एवं खनिजों का परिवहन करना है।


English

Xylem is a complex permanent tissue because it consists of more than one type of cell working together to perform a common function.

Its components include:

  • Tracheids
  • Vessels
  • Xylem Parenchyma
  • Xylem Fibres

Its primary function is the transport of water and minerals from roots to other parts of the plant.


Why Other Options Are Simple Tissues / अन्य विकल्प सरल ऊतक क्यों हैं?

A. Parenchyma (पैरेंकाइमा)

✔ Simple permanent tissue.

✔ Living cells with thin walls.

✔ Functions in storage, photosynthesis, and healing.


B. Collenchyma (कोलेन्काइमा)

✔ Simple permanent tissue.

✔ Provides flexibility and mechanical support.

✔ Cells have unevenly thickened corners.


C. Sclerenchyma (स्क्लेरेंकाइमा)

✔ Simple permanent tissue.

✔ Dead cells with thick lignified walls.

✔ Provides rigidity and strength.


Important Facts / महत्वपूर्ण तथ्य

Classification of Permanent Tissues

Simple Permanent Tissues (सरल स्थायी ऊतक)

  1. Parenchyma (पैरेंकाइमा)
  2. Collenchyma (कोलेन्काइमा)
  3. Sclerenchyma (स्क्लेरेंकाइमा)

Complex Permanent Tissues (जटिल स्थायी ऊतक)

  1. Xylem (जाइलम)
  2. Phloem (फ्लोएम)

Exam Point / परीक्षा बिंदु

Simple Tissue = Parenchyma + Collenchyma + Sclerenchyma

Complex Tissue = Xylem + Phloem

यह प्रश्न SSC, Railway, UPSC, State PSC, NEET, CUET और Teaching Exams में बार-बार पूछा जाता है।


One-Liner / एक पंक्ति में

Xylem is not a simple tissue; it is a complex permanent tissue responsible for the transport of water and minerals in plants.

जाइलम सरल ऊतक नहीं है; यह एक जटिल स्थायी ऊतक है जो पौधों में जल एवं खनिजों के परिवहन का कार्य करता है।
