Solanaceae Family Characteristics — NEET Biology
📚 Practice ConceptPlants mostly herbs, shrubs and rarely small trees Stem: herbaceous rarely woody, aerial; erect, cylindrical, branched, solid or hollow, hairy or glabrous, underground stem in potato (Solanum tuberosum) Leaves: alternate, simple, rarely pinnately compound, exstipulate; venation reticulate
Which of the following statements about the stem are correct? S1: The stem develops from the plumule of the embryo and characteristically possesses regions called nodes where leaves are borne, separated by internodes. S2: Axillary buds, located in the axil of leaves, have the potential to develop into branches, whereas terminal buds contribute to the primary growth of the main stem axis. S3: Besides bearing leaves, flowers, and fruits, stems are also involved in the conduction of water, minerals, and photosynthates. S4: While stems primarily spread branches and conduct substances, they rarely perform functions like food storage, support, or vegetative propagation. S5: Stems are always aerial, erect, and woody, never modified for underground food storage or protection.
