I. Coralloid roots
II. Unbranched stems
III. Pinnate persistent leaves for a few years
IV. Male cones and megasporophyllys borne on same plant
- a)I and II only
- b)I and IV only
- c)I, II and III only
- d)I, II, III, and IV
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
The features seen in the gymnospermCycasinclude:I. Coralloid rootsII. ...
The correct answer is: C: I, II, and III only
- I. Coralloid roots: Gymnosperm Cycas has coralloid roots that contain symbiotic cyanobacteria, aiding in nitrogen fixation.
- II. Unbranched stems: Cycas exhibits unbranched stems, which is a characteristic feature of this gymnosperm.
- III. Pinnate persistent leaves for a few years: Cycas has pinnate leaves that persist for several years, contributing to its distinct appearance.
- IV. Male cones and megasporophylls borne on the same plant: This option is incorrect as male and female reproductive structures are typically on separate Cycas plants.
- I. Coralloid roots: Gymnosperm Cycas has coralloid roots that contain symbiotic cyanobacteria, aiding in nitrogen fixation.
- II. Unbranched stems: Cycas exhibits unbranched stems, which is a characteristic feature of this gymnosperm.

Overview of Cycas Features
Cycas, a prominent representative of gymnosperms, exhibits several distinctive features that enhance its adaptability and reproductive strategies. Let's explore the features mentioned in the question.
Coralloid Roots
- Cycas develops **coralloid roots** that contain symbiotic cyanobacteria.
- These roots help in nitrogen fixation, benefiting the plant by improving nutrient availability.
Unbranched Stems
- The **stems of Cycas** are typically unbranched, contributing to its unique appearance.
- This feature allows for a more straightforward structure, focusing resources on leaf and reproductive development.
Pinnate Persistent Leaves
- Cycas possesses **pinnate leaves** that can remain persistent for several years.
- These leaves are adapted for photosynthesis and can efficiently capture sunlight, aiding in the plant's growth.
Male Cones and Megasporophylls
- In Cycas, both **male cones** (strobili) and **megasporophylls** (female structures) can be found on the same plant, indicating it is dioecious.
- This arrangement allows for efficient reproduction and genetic diversity as it can potentially self-fertilize.
Conclusion
The correct answer is option **C: I, II, and III only**.
- Although Cycas does possess coralloid roots, unbranched stems, and persistent pinnate leaves, it is important to note that while male cones may be present on the same plant, the female structures are typically borne separately. Therefore, option C accurately reflects the features inherent to Cycas, excluding the incorrect pairing of features regarding the cones and megasporophylls.
