Question

The scientist Nitsch was able to get strawberries of different shapes by

• A. Splitting the ovary
• B. Removing the perianth
• C. Selectively removing some carpels
• D. Inserting an alcohol dipped needle into ovary

Answer 1

Answer: (C)

Selectively removing some carpels

Strawberries develop from a single flower that is having multiple numbers of the gynoecium. Individual ovaries are called fruitlets and arranged around a thick part of the stem called receptacle. It is also called aggregate fruit. Other examples include raspberry, blackberry etc. In a young fruit, carpels are removed within a few days after pollination. Nitsch carefully removed the carpels in order to obtain differently shaped strawberries. It is because receptacle will not grow in the region where carpels are removed.

So the correct option is C
