Which of the following is true about a specialized companion cell of the phloem that is connected to the palisade mesophyll cell by plasmodesmata?
|
|
The specialized companion cell and the palisade mesophyll cell have highly specialized unrelated functions. |
|
|
Materials synthesized in photosynthesis could be sent form the mesophyll cell to the companion cell. |
|
|
The companion cell would have a thicker secondary cell wall than the palisade mesophyll cell. |
|
|
Sieve plates would be found in the companion cell but not in the palisade mesophyll cell. |
|
|
The companion cell lacks a nucleus, and the palisade mesophyll cell has a nucleus at maturity. |
