Offsets are produced by
Show Hint
Offset is a vegetative part of a plant that is made up of mitosis.
- Parthenogenesis
- Meiotic divisions
- Parthenocarpy
- Mitotic divisions
The Correct Option is D
Approach Solution - 1
Offsets are a plant's way of reproducing asexually, creating new daughter plants. They are formed through mitotic division of the main stem, resulting in genetically identical clones.
- Parthenocarpy is the development of fruit without fertilization.
- Parthenogenesis refers to the creation of an embryo from an unfertilized egg.
- Meiotic divisions are reduction divisions, producing daughter cells with half the number of chromosomes compared to the parent cell.
The correct answer is option D.

Approach Solution -2
Offsets are a fascinating means of asexual reproduction in plants. Through the process of mitotic divisions, plants generate new daughter plants that are genetically identical to the parent plant. Offsets are specialized structures produced by plants for vegetative reproduction.
Asexual Reproduction
- Asexual reproduction involves the production of new individuals without the need for fertilization.
- Offsets are an example of asexual reproduction, as they arise from a single-parent plant without the need for pollination.
Mitotic Divisions
- Mitosis is the process of cell division that occurs in somatic (non-sex) cells.
- Offsets are generated through mitotic divisions of cells in the main stem or branch of a plant.
- During mitosis, the genetic material is duplicated and equally distributed to two daughter cells.
- This results in genetic continuity between the parent plant and the offset.
Genetic Identity and Clones
- Offsets are considered clones of the parent plant because they are genetically identical.
- The genetic material present in the parent plant is replicated and passed on to the offset cells during mitotic divisions.
- This genetic continuity ensures that the offspring (offset) retains the same characteristics and traits as the parent plant.
Offsets are a remarkable example of asexual reproduction in plants, where new daughter plants are formed through mitotic divisions. These genetically identical clones serve as a means of propagation, allowing plants to reproduce and adapt to their environment.

Concepts Used:
Asexual Reproduction
The mode of reproduction in which a new offspring is produced by a single parent is known as asexual reproduction. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents.
Features of Asexual Reproduction:
- Only single parents are involved.
- The fertilization or gamete formation cannot take place.
- This process of reproduction occurs in a very short time.
- The organisms multiply and grow rapidly.
- In this offspring produced is genetically similar.
