Which of the following plants tissues cannot be used as explant in tissue culture?
A
Sclerenchyma
B
Collenchyma
C
Meristem
D
Parenchyma
Answer
Sclerenchyma
Explanation
Solution
An explant is a piece of plant tissue or part which is used in tissue culture for regeneration. It is used to grow a new plant in a cultured medium. Meristem, collenchyma and parenchyma are made up of living cells. Thus they can be used as explants. Whereas sclerenchyma is made up of dead cells, thus it cannot be used as an explant.
