I have a question.


Why do farmers cut off the leaves of the radish before selling them?

Thanks

Just my guess - to prevent loss of water thru the leaves.

The food stored in the radish may be utilised by the radish to grow into a young plant and the radish will shrink in size.

Because nobody wants to carry the leaves home to throw it away, and of course farmers don't want to bring extra load to the market. More importantly buyer do not want to pay for extra weight

Have you seen radish or carrot seeds?
These plants reproduce by a method called vegetative propagation.
Others such plants include ginger, potato, onion etc.

I don't really know how exactly they reproduce in this manner because reproduction needs a male reproductive cell and a female reproductive cell.

Maybe a Science teacher can help to elaborate more.
