Plant Kingdom

The floral formula given represents the family Liliaceae. Allium cepa, Gloriosa superba, and Dracaena angustifolia are members of Liliaceae, making option (3) correct. The other groups belong to Solanaceae or unrelated families.

Utricularia, also known as bladderwort, is a free-floating, submerged aquatic plant that remains suspended in water. Others like Salvinia float on the surface, while Vallisneria and Nymphaea are rooted.

When seeds are soaked in water, water moves along a concentration gradient by imbibition and osmosis, leading to seed swelling and germination. The option about no affinity between adsorbent and liquid contradicts the basic principle of imbibition, which depends on such affinity.

Dryopteris is a fern, which belongs to the pteridophytes. Pteridophytes exhibit features like ramenta (brown hair-like appendages), archegonia (female sex organs), and circinate vernation (coiled young leaves). These traits are not present together in gymnosperms like Pinus and Cycas or in bryophytes like Funaria.

All statements are correct. Quiescence is due to an immature embryo. The seed coat of Fabaceae acts as a barrier to water and oxygen. Tomato seed germination is inhibited by certain chemicals in the seed coat, and polygonum seeds need chilling (low temperature) to break dormancy.

Hydrophytes typically have epistomatous leaves, which are characterized by having stomata on the upper surface of the leaves. This is in contrast to plants with hypostomatous leaves, which have stomata on the lower surface.

Marchantia is a primitive land plant (Bryophyte); Ginkgo is an archegoniate phanerogam; Spirogyra is an autotrophic thallophyte with a haplontic life cycle; Selaginella is a heterosporous non-flowering plant.

The features that are not characteristics of dicotyledonous roots include the vascular bundles being in the range of 15–20 and the failure to develop a cambium ring.
Thus, the correct answer is (C, D).

The correct pairings are:
- Clostridium causes Botulism.
- Diplococcus causes Pneumonia.

Deficiency of calcium (Ca), magnesium (Mg), copper (Cu), and potassium (K) can cause necrosis or death of leaf tissue in plants. These nutrients are vital for cell function and plant health.

I. Algae of class Phaeophyceae includes {Sargassum} – Correct.
II. {Marchantia} belongs to Hepaticopsida, a class of Bryophytes – Correct.
III. {Equisetum} is a pteridophyte but not from class Pteropsida – Incorrect.
IV. {Pinus} belongs to Coniferopsida, not Gnetopsida – Incorrect.
