Question

Examine the figure A, B, C, and D in which of the following one of the four options all the items are correct?

I. A- Selaginella, B- Equisetum, C- Salvina, D- Ginko
II. A- Equisetum, B- Ginko, C-Selaginella, D-Lycopodium
III. A- Chara, B- Marchinta, C- Fucus, D-Pinus
IV. A- Funaria, B- Adiantum, C-Salvina, D-Riccia

Answer 1

Hint: From the picture A,B,C and D it is clear that they are advanced plants. In the picture, we can see that plants have a clear division of roots, stem, and leaves indicating that plants belong to Pteridophytes and Gymnosperm.

Complete answer:
Selaginella: Belong to Pteridophytes. In picture A it is clear that plants have true roots, stems, and leaves. Leaves are small in size. Short leaves refer to microphylls. In Selaginella, the main plant body is the sporophyte. Selaginella sporophylls form a distinct compact structure called strobili or cones.
Equisetum: Equisetum belongs to Pteridophytes and the family Horsetails. It is the only live plant in their genus so it is also known as a living fossil. It is a perennial herbaceous plant. From the picture(B) we can see the strobilus part, node, internode, and rhizome. Equisetum has an underground stem called a rhizome.
Salvina: Saliva also belongs to Pteridophytes. Salvina is a fern. Fern has large leaves. Large leaves are known as macrophylla. As we can see in picture C the plant has large leaves.
Ginkgo: Belong to gymnosperm, gymno means naked and sperma means seeds are plants in which ovary walls do not cover ovules and remain open. As we can see in picture D the seeds are visible.
So, the correct option is option (I).

Note: Marchinta, Riccia, and funaria belong to bryophytes, and Lycopodium and Adiantum belong to pteridophytes and Chara and fucus belong to algae, and Pinus belong to gymnosperm. Pteridophytes are the first terrestrial plant possessing a vascular system for food, water, and mineral transport in the plant. Gymnosperm are plants that bear naked seeds. Angiosperms are plants that produce flowers and that is why angiosperms are also known as flowering plants. In angiosperms, the seed is enclosed by flowers.
