Statement-I: Vessels and tracheids of the roots, stems and leaves are interconnected to form a continuous system of water-conducting channels in the plants. Statement-II : The transport of soluble products of photosynthesis is called transpiration and it occurs in the phloem tissue.Consider the given statements and select the correct option.Only one correct answerA.Only statement-II is correctB.Only statement-I is correctC.Both the statements are incorrectD.Both the statements are correct

Statement (A) :- Plants transports of food in the form of sucroseStatement (B) :- Transportation of food takes place in the companion cells the help of phloem fibersStatements (A) is correct, (B) is incorrect

Water, sugar, and other important nutrients need to be transported from one part of a plant to another. Which statement correctly describes the interaction of the root and shoot systems during nutrient transport?Ask Studybuddy (Login to use)Group of answer choicesThe leaves take in water and sugar, which are then transported to the rest of the plant through vascular tissues.The roots take in water and sugar, which are then transported to the rest of the plant through vascular tissues.The leaves take in water and the roots produce sugar that are transported to the rest of the plant through vascular tissues.The roots take in water and the leaves produce sugar that are transported to the rest of the plant through vascular tissues

32. Which of the following statements is NOT acceptable? Phloem unloading may:A. involve the conversion of sucrose to glucose and fructose during apoplastic transport.B. move sucrose through the plasmodesmata to sink cells in symplastic transport.C. more frequently involve apoplastic transport in root sinks and symplastic transport in fruit sinks.D. be inhibited by the endodermis which will prevent the lateral transport of photosynthates.E. involve the transport of photosynthates from sieve elements into parenchyma cells.

1What is transpiration in plants?The absorption of water by the root hair cellsThe absorption of water through the leavesThe movement of water through a plant due to evaporation from the leavesThe movement of water through the phloem cells2Which substances enter and leave the plant through the stomata?Oxygen enters; carbon dioxide and water leaveCarbon dioxide and water enter; oxygen leavesWater and oxygen enter; carbon dioxide leavesCarbon dioxide enters; water and oxygen leaves3Which cells control the opening and closing of the stomata?Palisade cellsPhloem cellsGuard cellsXylem cells4What happens to the rate of transpiration when the temperature is increased?It stays the sameIt increasesIt decreasesIt stops altogether5Why does the rate of transpiration decrease in very humid conditions?Because there will be more water inside the leaf than in the air Because the rate of photosynthesis increasesBecause the rate of photosynthesis decreasesBecause there will be less water inside the leaf than in the air6Why are stomata normally found on the underside of leaves?So that they are shaded from the sunSo that they are nearer the ground So that they are protected from rainTo allow water to escape from the leaves by gravity
