Current Question (ID: 12388)

Question:

Which of the given feature is not related to mustard?

Options:

1. Superior ovary.
2. Variable length of filaments of stamens.
3. Parietal placentation.
4. Opposite phyllotaxy.

Solution:

Opposite phyllotaxy refers to the arrangement of leaves in pairs at the nodes of a stem, with each pair of leaves being positioned opposite to each other. This particular feature is not related to mustard. Mustard is a flowering plant that belongs to the family Brassicaceae and is characterized by features such as superior ovary, variable length of filaments of stamens, and parietal placentation. However, it does not exhibit opposite phyllotaxy in its leaf arrangement. Mustard typically has alternate or spiral leaf arrangement on the stem, not opposite phyllotaxy.
