Which of the following plants has 'hidden reproductive organs'?

Correct option is A

The correct answer is (A) Marsilea.

Explanation:
Marsilea is a fern that has "hidden reproductive organs." Its reproductive organs, called sporangia, are located within specialized structures on the leaves and are not externally visible. This makes the reproductive process less apparent compared to other plants.

Information Booster:

• Marsilea: Known as "water clover," this aquatic fern reproduces using spores contained in its specialized sporangia. It thrives in aquatic environments such as ponds and marshes.
• Reproduction in Marsilea: It is a form of asexual reproduction through spores, hidden in its leaves, which are adapted to aquatic life.

Additional Information:

• Pinus: A conifer that has visible reproductive organs in the form of cones. Its reproductive structures are externally visible.
• Deodar: A type of conifer, like Pinus, which also has visible reproductive cones.
• Ipomoea: A flowering plant, with visible flowers and reproductive organs. It is not a fern and does not have hidden reproductive organs.
