Question

Which statement is correct for apomixis?
A. Without fertilization diploid embryo forms
B. With fertilization diploid embryo forms
C. Without fertilization haploid embryo cell form embryo
D. With fertilization haploid embryo cell form embryo

Answer 1

Apomixis (is regarded as asexual seed formation) is a process in which the most fundamental aspects of sexual reproduction are bypassed by a plant, including meiosis and a viable seed produced by fertilization.

Complete answer: The process of reproduction is necessary in order to maintain the life of the line on earth. The process of the creation of a new organism from a pre-existing organism of a similar nature is called reproduction. The reproductive process can be divided into asexual and sexual reproduction depending on the participation of gametes.
In flowering plants, apomixis is characterized as the asexual formation of a seed from the ovule's maternal tissues, avoiding the meiosis and fertilization processes, leading to the development of the embryo. Through the fusion of mitotically reduced egg cells and pollen grains, most plant species develop genetically variable seeds. However, through the apomixis process, a small proportion of seed plants develop clonal, asexual seeds. A drawback of apomictic seeds is that due to a lack of variations in asexual reproduction, it decreases genetic diversity from parent to offspring plants.
Apomixis refers to mechanisms that circumvent meiosis when an embryo sac is mitotically produced from a diploid cell in the ovule. Apomictic-based embryonic plants have the same genetic characteristics as parents, which allows them to be called clones.
The mother cell thus is diploid, so it forms diploid embryos.

Therefore, the right response is A- ‘Without fertilization diploid embryo forms.

Note: Apomixis is an asexual reproductive procedure, but it should not be confused with fertilization. It is important to note the various techniques of apomixis or its forms along with its benefits. Apomixis provides many agronomical advantages: fast generation and reproduction of superior forms by seed from new germplasms, currently underutilized; reduced costs and breeding time are benefits of apomixis.
