Pteris এর পরিবহন কলাগুচ্ছকে হ্যাড্রোসেন্ট্রিক বলার কারণ

উত্তর : যে সকল ভাস্কুলার বান্ডলে জাইলেম কেন্দ্রে অবস্থান করে ও সম্পূর্ণরূপে ফ্লোয়েম দিয়ে পরিবেষ্টিত থাকে তাকে হ্যাড্রোসেন্ট্রিক বা জাইলেম কেন্দ্রিক ভাস্কুলার বান্ডল বলা হয় । Pteris উদ্ভিদের ভাস্কুলার বান্ডল বা পরিবহন কলাগুচ্ছের ক্ষেত্রে দেখা যায় যে , জাইলেম কেন্দ্রে থাকে এবং ফ্লোয়েম তাকে পরিবেষ্টিত করে রাখে । এজন্য Pteris এর পরিবহন কলাগুচ্ছকে হ্যাড্রোসেন্ট্রিক বলা হয় ।
