Explanation Based on its characteristics, the plant belongs to th e class dicotyledons (or dicots). Vein network on leaves: Dicots have leaves with a complex, branching, and interconnected vein pattern known as reticulate venation. In contrast, monocots typically have parallel venation. 8 petals: Dicot flowers most commonly have petals in multiples of four or five. Since eight is a multiple of four, it is a strong indicator of a dicot plant. Monocot flowers typically have petals in multiples of three.
پیاز کا پتی لیس تنے جس کو پھول برداشت کرنے کے لئے تیار کیا جاتا ہے اسے ______ کہا جاتا ہے؟
A. Scape
B. Peduncle
C. None of these
D. Rachis
Check answer and explanation
Answer: Scape
Explanation Scape is a leafless flower-bearing stem that arises from the ground in plants like onions and lilies . It helps elevate the flower above the leaves for better pollination.
پودوں میں ، معدنیات کی نیچے کی طرف نقل مکانی _____ کے ذریعے ہوتی ہے؟
A. None of these
B. Xylem
C. Cortex
D. Phloem
Check answer and explanation
Answer: Phloem
Explanation In plants, xylem mainly transports water and minerals upward. Phloem carries organic food and minerals both upward and downward , enabling downward translocation.
ایک گروہ پودوں کا جو ایک جیسی خصوصیات اور ماحول رکھتا ہو، اسے کیا کہتے ہیں؟
A. Plant Species
B. Genus
C. Family
D. None of these
Check answer and explanation
Answer: Plant Species
Explanation Plants are classified based on shared characteristics and natural environment. A plant species is the basic unit of classification where plants can reproduce among themselves. Additional information : A species is capable of natural reproduction within its group. Example: Triticum aestivum (common wheat) is a plant species. Last verified on 22-01-2026
واضح طور پر ترتیب دیئے گئے پتلی دیواروں والے پیرینچیما خلیوں کا ایک بے ساختہ بڑے پیمانے پر جو وضاحت سے تیار ہوتا ہے اسے _____ کہا جاتا ہے؟
A. Callus
B. Thalius
C. None of these
D. Callose
Check answer and explanation
Answer: Callus
Explanation Callus is an unorganized mass of parenchyma cells that forms in plant tissue culture from an explant. It serves as a precursor for organ or shoot regeneration in tissue culture.
بولٹنگ سے مراد کس فصل میں پھولوں کے جھرمٹ کا ظہور ہے؟
A. Sugarbeet
B. None of these
C. Potato
D. Sugarcaner
Check answer and explanation
Answer: Sugarbeet
Explanation Bolting is the rapid growth of the flowering stem (inflorescence). Observed in sugarbeet , where the plant shifts from vegetative to reproductive stage. Causes reduced root yield and sugar content . Triggered by long day conditions or stress. Important to manage for better crop harvest . Last verified on 12-02-2026
Explanation Bread wheat (Triticum aestivum) is the most widely grown wheat worldwide. It has six sets of chromosomes (hexaploid, 2n = 6x = 42). Hexaploid nature gives it genetic diversity and high yield potential. Originated from natural hybridization between tetraploid wheat and wild grass. Used mainly for bread, flour, and bakery products . Last verified on 12-02-2026
Explanation Fruits are not found in Gymnosperms because they lack an ovary , meaning their seeds are "naked" (unenclosed), developing on the surface of scales (like in cones) rather than inside a protective fruit wall, a key difference from Angiosperms (flowering plants).
جینوں کو اعلی ٹرانسجینک پودوں میں منتقل کرنے کے لئے مندرجہ ذیل میں سے کون سا استعمال کیا جاتا ہے؟
A. None of these
B. Cosmid
C. Lambda phage
D. Ti-plasmid
Check answer and explanation
Answer: Ti-plasmid
Explanation Ti-plasmid (Tumor-inducing plasmid) from Agrobacterium tumefaciens is commonly used for gene transfer in higher transgenic plants. It integrates the desired gene into the plant genome , enabling genetic modification.
