एक पुष्प की लम्बवत काट में निषेचन क्रिया का प्रदर्शन
Understand the Problem
यह प्रश्न एक फूल के प्रजनन के बारे में जानकारी मांग रहा है, विशेष रूप से अंडाणु, पराग कण और पोलन ट्यूब के बारे में। इसमें दिए गए चित्रदर्श को देखते हुए, यह प्रकरण फूल की संरचना और प्रजनन प्रक्रिया को स्पष्ट करने का प्रयास कर रहा है।
Answer
The diagram illustrates fertilization in a flower, showing pollen tube formation and interaction with ovule cells.
The diagram shows the longitudinal section of a flower during the fertilization process. The pollen grain germinates on the stigma and grows a pollen tube that reaches the ovule. Fertilization occurs when the male nuclei in the pollen tube unite with the egg cell and polar nuclei in the ovule.

More Information
In flowering plants, fertilization involves the fusion of male gametes with the female ovule. This typically involves a pollen tube that delivers sperm cells to an embryo sac containing the egg cell.
Tips
A common mistake is confusing the role of synergids and antipodal cells. Synergids assist in guiding the pollen tube to the egg cell.
