Introduction:
Wolffia is a genus of tiny aquatic plants commonly known as watermeal. These plants belong to the family Lemnaceae and are found in freshwater habitats across the globe. Wolffia is unique in its appearance and reproductive strategies, which makes it an interesting subject of study in the field of botany.

Angiosperm or Gymnosperm:
Wolffia is an angiosperm, specifically a flowering plant. Angiosperms are characterized by the presence of flowers and enclosed seeds within fruits. Gymnosperms, on the other hand, are non-flowering plants that produce naked seeds (not enclosed within a fruit). Let's explore the reasons why Wolffia falls under the category of angiosperms.

Key Points:
- Wolffia is a flowering plant, and it produces tiny flowers that are typically inconspicuous and easy to miss due to their size.
- The flowers of Wolffia are unisexual, meaning they have separate male and female flowers on the same plant.
- The male flowers of Wolffia produce pollen, while the female flowers contain ovules.
- Fertilization occurs when pollen is transferred from male flowers to female flowers, leading to the formation of seeds.
- The seeds of Wolffia are enclosed within a protective structure called the pericarp, which develops into a fruit-like structure.
- The fruit of Wolffia is small and often difficult to observe without magnification. It serves to protect the seeds and aid in their dispersal.
- Unlike gymnosperms, which have exposed seeds, the seeds of Wolffia are enclosed within the fruit, a characteristic feature of angiosperms.

Conclusion:
In conclusion, Wolffia belongs to the category of angiosperms, as it is a flowering plant that produces small flowers and encloses its seeds within fruits. The presence of these reproductive structures and strategies sets Wolffia apart from gymnosperms, which lack flowers and fruits. The unique characteristics of Wolffia make it an interesting subject for further study and exploration in the field of botany.
