Question 5
Tissue culture takes material from the apical bud, the lateral bud or the root tip. Why those three places?
The right answer is the one marked above.
They are the meristematic regions, where cells still divide and have not specialised. Apical bud, lateral bud and root tip are exactly the sites of the three meristems.
A cell that has already committed to being one thing is far harder to grow into a whole new plant. Undifferentiated is the property tissue culture depends on.
