Explanation The protonema is the filamentous, early growth stage of mosses that develops from spores. It closely resembles multicellular green algae in structure and appearance.
پودوں کے کن اعضاء کو پودے کی فوڈ فیکٹری بھی کہا جاتا ہے؟
A. Leaves
B. Roots
C. Flowers
D. Stems
Check answer and explanation
Answer: Leaves
Explanation Leaves are called the food factory of plants . They prepare food through the process of Photosynthesis . Chlorophyll in leaves absorbs sunlight to make food. Photosynthesis uses Carbon dioxide (CO₂), Water (H₂O), and Sunlight. Food produced is mainly Glucose , which provides energy to the plant. Last verified on 13-03-2026
پودوں کے تولیدی طرز عمل کو ان کے ماحول کے ساتھ ہم آہنگی _____ کے ذریعہ کی جاتی ہے؟
A. Transpiration and Vernalization
B. None of these
C. Photoperiodism and Vernalization
D. Respiration and Vernalization
Check answer and explanation
Answer: Photoperiodism and Vernalization
Explanation Photoperiodism is the response of plants to the length of day and night , influencing flowering and reproduction. Vernalization is the requirement of a cold period to induce flowering in certain plants.
مندرجہ ذیل میں سے کون سا جوڑا ہے ، صحیح طور پر مماثل نہیں ہے؟
A. Gibberellic acid-Leaf fall
B. Abscisic add-Stomatal closure
C. None of these
D. IAA-Cell wall elongation
Check answer and explanation
Answer: Gibberellic acid-Leaf fall
Explanation Gibberellic acid promotes stem elongation, seed germination, and flowering rather than leaf fall. Leaf fall (abscission) is mainly regulated by abscisic acid (ABA) and ethylene.
ٹنڈرا اوپر کی مٹی منجمد ہے اور اسی وجہ سے اسے _____ کے نام سے جانا جاتا ہے؟
A. Permafrost
B. Hemifrost
C. Eufroat
D. None of these
Check answer and explanation
Answer: Permafrost
Explanation Permafrost refers to soil that remains frozen year-round in Tundra regions . It prevents deep-rooted plants from growing and significantly affects the ecosystem.
Explanation Taiga, also called boreal forest, occurs in high northern latitudes. Characterized by long, cold winters and short, mild summers. Snow cover persists for much of the year. Dominated by coniferous trees like pine, spruce, and fir. Adapted for cold climate with needle-like leaves and conical shape to shed snow.
Explanation Pteridophytes were the first plants to develop vascular tissues. This leading to the evolution of seed habit in higher plants. Algae, bryophytes, and fungi do not produce seeds; they reproduce through spores.
Explanation This pathway refers to the movement of water through the cell walls and the spaces between cells, essentially the non-living parts of the plant tissue.
