Question
Which of the following is not a part of the plant’s translocation machinery?
Select an answer
- A. Companion cells
- B. Sieve tubes
- C. Vessels
- D. Parenchyma
Solution
The correct answer is C. Vessels.
Here's why:
A. Companion cells - These are part of the plant's translocation machinery. They are specialized parenchyma cells that assist in the function of the phloem, which is responsible for translocation.
B. Sieve tubes - These are also part of the plant's translocation machinery. They are a major component of the phloem and help in the transport of sugars and other nutrients.
C. Vessels - These are not part of the plant's translocation machinery. They are part of the xylem, which is responsible for the transport of water and minerals, not the translocation of sugars and other nutrients.
D. Parenchyma - These cells can be part of the plant's translocation machinery. They are involved in many functions in plants, including storage and transport.
