TRANSPORT IN PLANT

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In plants, translocation happens through ____
A
Xylem
B
Phloem
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Translocation is the movement of elements within a plant from leaves to other tissue. Plants’ phloem, a type of vascular tissue, is where translocation takes place. Sugars that are produced by photosynthesis or that are stored in plant tissues like roots, bulbs, and tubers are examples of sugar sources.

Detailed explanation-2: -Transport of substances in the phloem is called translocation . Translocation requires energy as it is an active process. Phloem consists of living cells.

Detailed explanation-3: -Phloem translocation is generally believed to be driven by pressure and is achieved by utilizing energy. Material like sucrose is transferred into phloem tissue using energy from ATP. This increases the osmotic pressure of the tissue causing water to move into it.

Detailed explanation-4: -Translocation is the movement of sugar produced in photosynthesis to all other parts of the plant for respiration and the other processes described above. This occurs in phloem cells.

Detailed explanation-5: -Translocation occurs through part of vascular tissue known as phloem that also transports carbohydrates, amino acids and other substances such as plant hormone which are made in tips of roots and shoots to the storage and growing organs. Was this answer helpful?
