Exanthema is due to deficiency of Mo Cu Mn B 2. When we talk about the "food factories" in a leaf, what specific parts of the leaf are we referring to? Chloroplasts Chlorophyll Sponge cell Stoma 3. Element essential for photolysis of water is Carbon Chlorine Oxygen Nitrogen 4. What is the source of light used in photosynthesis? Sun LED Moon Star 5. Raw materials for photosynthesis include water all of the above organic nutrients light 6. In this process, which occurs in plants and animals, sugars and oxygen join to produce water, carbon dioxide, and energy. What is the process? Photosynthesis Hydrogenation Respiration Transpiration 7. Gray spots of oat are caused by deficiency of Fe Cu Mn Zn 8. Deficiency of mineral nutrients is not responsible for Chlorosis Etiolation Necrosis Shortening of internodes 9. What chemical enters the leaf from the air? Carbon dioxide Chlorophyll Oxygen Nitrogen 10. The mode of nutrition in a green plant is ………… Autotrophic Heterotrophic Saprophytic Holozoic 11. Pigment leghemoglobin is present in roots of Maize Potatoe Soybean Rice 12. Function of zinc is Biosynthesis of 3-IAA Oxidation of carbohydrate Closing of stomata Synthesis of chlorophyll 13. Most plants obtain their nitrogen from the soil in the form of Nitric acid Nitrates Nitrogen oxide Free nitrogen gas 14. Conduction of inorganic materials in plants occur mainly through minerals absorbed by roots move to the leaf through Sieve tube Xylem Phloem None of these 15. Even in the presence of sunlight and water, photosynthesis cannot occur due to lack of carbon dioxide essential metallic elements essential non metallic elements mineral nutrient 16. Carrier proteins are involved in Water evaporation Passive transport Water transport Active transport 17. Cultivation by sand culture is also called Photorespiration Protein synthesis Soil-less cultivation Green house effect 18. Which of the following describes the characteristic of a living being? Respiration Excretion Nutrition All the above 19. Essential macro elements are Manufactured during photosynthesis Produced by enzymes Absorbed from soil Produced by growth hormones 20. The process by which green plants prepare their own food is known as …… Respiration Symbiosis Photosynthesis None of these 21. What is the other substance that is released into the air when the leaf makes its food? Oxygen Glucose Carbon dioxide Water 22. An example of an autotrophic plant is ………… Dodder Mould Neem Mushroom 23. Carnivorous plants are found on Nitrogen deficient soil CO2 deficient soil O2 deficient soil None of these 24. Plants absorb mineral salts from the soil solution through A semipermeable membrane into the cytoplasm The cell wall which is semipermeable Perforation at the apex of rot hair cells None of these 25. Hydroponics are Growing of plants in sand Growing of floating aquatic plants Growing of aquatic plants Growing of plants aqueous balanced nutrient 1 out of 25 Time is Up! Time's up
