In Welwitschia, the exposed massive woody, concave disk produces only two strap-s ed leaves.
Ephedra has inconspicuous small, scalelike leaves.
In Pinus seed, the seedcoat and embryo are diploid and the female gametophyte is haploid.
In Cycas the male strobilus (cone) and megasporophyils occur on the same plant.

Answer 1

The correct answer is In Cycas the male strobilus (cone) and megasporophylls occur on the same plant.

Concept:

Gymnosperms are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes.
They are characterized by the presence of naked seeds, usually on cones or strobili, and do not produce flowers or fruits.
Gymnosperms have a distinct alternation of generations, with a dominant sporophyte generation and a reduced gametophyte generation.
They exhibit a variety of morphological adaptations and reproductive strategies.

Explanation:

Welwitschia: Welwitschia mirabilis is a unique gymnosperm found in the Namib Desert. It produces only two large, strap-shaped leaves that grow continuously from a massive, woody, concave disk. This statement is correct.
Ephedra: Ephedra, also known as joint pine, is a genus of gymnosperms with small, scale-like leaves. These leaves are often reduced to minimize water loss in arid environments. This statement is correct.
Pinus Seed: In Pinus (pine trees), the seed coat and embryo are diploid, originating from the parent sporophyte, while the female gametophyte is haploid, originating from the megaspore. This statement is correct.
Cycas: In Cycas, the male strobilus (cone) and megasporophylls (female reproductive structures) do not occur on the same plant.
- Cycas is dioecious, meaning that male and female reproductive structures are found on separate plants. This statement is incorrect, making it the correct answer to the question.
