<p><strong>Sol.</strong> If the female parent produces unisexual flowers, there is no need for emasculation.</p>
<ul>
<li>
<p>The female flower buds are bagged before the flowers open.</p>
</li>
<li>
<p>When the stigma becomes receptive, pollination is carried out using the desired pollen and the flower rebagged.</p>
</li>
<li>
<p>This protects them from contamination by unwanted pollen grains.</p>

<p><strong>Sol.</strong> Apomixis is the phenomenon of formation of seeds without fertilisation.</p>
<ul>
<li>
<p>These embryos are genetically identical to the parental plant.</p>
</li>
<li>
<p>Other options are not correct because parthenocarpy and apomixis are different phenomenon.</p>
</li>
<li>
<p>Parthenocarpy is the formation of fruits without fertilisation and hence the fruits are seedless e.g., banana.</p>

<p><strong>Sol.</strong> In some species, the diploid egg cell is formed without reduction division and develops into an embryo without fertilisation.</p>
<ul>
<li>It is an asexual reproduction which occurs in the absence of pollinators or in extreme environments.</li>
<li>In some species like citrus plants, nucellar cells surrounding the embryo sac start dividing and develops into embryos.</li>

<p>It occurs in the megaspore mother cell without undergoing meiosis, and produces diploid embryo sac through mitotic divisions.</p>
</li>
<li>
<p>It helps in the preservation of desirable characters for indefinite period.</p>
</li>
<li>
<p>Thus, it can be concluded that apomictic species produce diploid cells.</p>
</li>
<li>
<p>Haploid cells will be formed during sexual reproduction when cell will undergo meiosis and option ‘c’ and ’ $d$ ’ is not shown by megaspore mother cell.</p>
