Q. Offsets are produced by :
(a) Meiotic divisions
(b) Mitotic divisions
(c) Pathenocarpy
(d) Parthenogenesis
Solution :
Correct Option : B Offset is part of branch or stem by which a plant can reproduce asexually and a new daughter plant is formed. Offset are the means of vegetative reproduction in plants. These are the clones and genetically identical to the plants. These are produced by the mitotic division of the main stem of the plant. (Because in mitosis, chromosome number remains same).•Parthenocarpy is the formation of fruit without fertilisation• Parthenogenesis is the formation of an embryo from an unfertilized egg.• Meiotic divisions are the reduction divisions which results in the formation of daughter cells having half the number of chromosome of a parent cell. So, the correct answer is option B.
