In a typical flower, germinating pollen grains pass through several parts of the gynoecium before they reach the ovule. A list of the parts of gynoecium is given below in different combinations. Choose the combination that represents the correct sequence of pollen tube pathway/journey :

Options

  1. AStyle, Stigma, Ovary
  2. BStigma, Style, Ovary
  3. CPistil, Stigma, Ovary
  4. DOvary, Pistil, Style

Correct answer

B. Stigma, Style, Ovary

Step-by-step solution

- The gynoecium is the innermost whorl of a flower; it consists of (one or more) pistils and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. - Carpels and pistils have three parts: a stigma at the top where the pollen lands; a style and an ovary - The correct pathway is Stigma, Style And Ovary
