Question

What is common between vegetative reproduction and Apomixis?
(a)Both occur round the year
(b)Both produces progeny identical to the parent
(c)Both are applicable only to dicots plants
(d)Both bypasses the flowering phase

Answer 1

Hint: Vegetative Reproduction is a form of asexual reproduction in plants in which new plants arise from a part of the parent plant or a specialized reproductive structure. So the newly formed plant will be much similar to the parent plant. Apomixis is a kind of asexual reproduction that occurs without fertilization and without the involvement of meiosis. Here also there are no chances for the formation of new genetic combinations.

Complete answer:
Both apomixis and vegetative reproduction produce progeny identical to the parent plant. As we already said in Vegetative reproduction the new plants arise from a part of the parent plant. So the resulting plant will be identical to the parent plant. Similarly, Apomixis refers to a kind of asexual reproduction in which new plants are formed without fertilization Thus in this case also the newly formed plant will be identical to the parent plant. The tuber of potato, the rhizome of ginger, etc. are examples of vegetative propagation.

Additional Information:
-Vegetative Reproduction occurs without gamete formation and fusion of male and female gametes. New plants arise from vegetative propagules such as rhizome, Tuber, etc.
- Vegetative reproduction is also known as vegetative propagation.
-Apomixis is a term derived from two Greek words 'Apo' and 'mixed'.

So, the correct answer is 'Both produce progeny identical to the parent'.

Note: -There are three types of apomixis namely, diplospory, apospory, and adventitious embryony. The embryo sac is derived from the megaspore mother cell in the case of diplospory.
-The nucellar cells give rise to the apomictic embryo sac in the case of apospory. Adventitious embryony refers to sporophytic apomixis, where embryos are produced directly from the nucellus of the integument of the ovule.
-Apomixis is common among higher plants. More than 35 families of plants are known to be apomictic e.g. Gramineae, Rosaceae, Compositae and Rutaceae, etc. Some cereals such as maize and wheat show apomixis.
