Question

Offsets are produced by:

• A. Parthenocarpy.
• B. Meiotic divisions.
• C. Parthenogenesis.
• D. Mitotic division.

Answer 1

The correct option is D

Mitotic division.

The correct option is D.

Explanation for the correct option:

1. Offsets are created when a plant's meristem region differentiates into a new plant with the capacity to support itself, such as axillary buds or homologous structures.
2. In species that produce underground storage organs like bulbs, corns, and tubers, this is typical.
3. Examples are lilies and tulips.
4. Offsets are a plant's vegetative component.
5. They develop by the process of mitosis, which happens in somatic cells.
6. Offsets are daughter plants that are created by sexual reproduction and are genetically related to the parent plant.

Explanation for the incorrect options:

Option A:

1. Parthenocarpy is the process of creation of fruits without fertilization, consequently, seedless fruits are created.
2. Banana is an example.

Option B:

1. The meiotic division is a two-step process that results in the production of cells, eggs, or sperm.
2. The number of chromosomes is decreased from 46 to 23 as a result of this process.

Option C:

Without fertilization, parthenogenesis is the process by which an embryo develops from an ovum.

Final answer: Offsets are produced by mitotic division.
