Question

Offsets are produced by

Accepted Answer

Correct Answer: B — Mitotic divisionsStep-by-step Solution:Offsets are short, lateral, horizontal branches that arise from the base of the parent plant. They are formed by repeated mitotic divisions of somatic (vegetative) cells. Each offset can develop roots and separate from the parent to form a new, genetically identical individual (clone). Examples include water hyacinth (Eichhornia) and Pistia.Why other options are incorrect:Option A (Meiotic divisions): Meiosis produces gametes (sex cells), which are involved in sexual reproduction, not in vegetative propagation like offsets. Option C (Parthenogenesis): Development of an organism from an unfertilized egg; involves gametes and is a form of asexual reproduction in animals, not applicable to offsets. Option D (Parthenocarpy): Development of fruit without fertilization (e.g., banana); unrelated to the formation of vegetative propagules.Key Concept: Vegetative reproduction is asexual and involves mitotic divisions, producing offspring genetically identical to the parent. Types of vegetative propagules include runners, stolons, offsets, rhizomes, suckers, bulbs, corms, and tubers.
