1. Fill in the blanks:<\/strong><\/span>
\n(a) Production of new individuals from the vegetative part of parent is called_____________.<\/span>
\n(b) A flower may have either male or female reproductive parts. Such a flower is called_____________.<\/span>
\n(c) The transfer of pollen grains from the anther to the stigma of the same or of another flower of the same kind is known as _____________.<\/span>
\n(d) The fusion of male and female gametes is termed as _____________.<\/span>
\n(e) Seed dispersal takes place by means of _____________, _____________ and _____________.<\/span><\/p>\n

Answer – <\/strong><\/span>
\n(a) Production of new individuals from the vegetative part of parent is called\u00a0vegetative propagation<\/strong><\/span>.<\/span>

2. Describe the different methods of asexual reproduction. Give examples.<\/strong><\/span><\/p>\n

Answer –\u00a0 <\/strong>There are six types of asexual reproduction. They are:<\/span><\/p>\n

Vegetative Propagation – <\/strong>In this asexual reproduction, new plants are produced from roots, stems, leaves and buds of the individual plant. Examples \u2013\u00a0<\/b>Tuber of potato, the rhizome of ginger.<\/span><\/p>\n

Budding – <\/strong>The bud is a small projection which gradually grows and gets detached from the parent cell and forms a new yeast cell. The new yeast cell grows, matures and produces more yeast cells. Example<\/b> \u2013 Yeast. <\/span><\/p>\n

Fragmentation – <\/strong>In this mode of reproduction, the growth and multiplication are done by rapidly breaking down into two or more fragments. Each fragment grows into new individuals when water and nutrients are available. Example \u2013<\/b> Algae
\n<\/span><\/p>\n

Spore Formation – <\/strong>This reproduction is done by spores which under favourable conditions germinates and develops into a new individual. Examples \u2013<\/b> Fungi like Rhizopus, Mucor, etc.
\n<\/span><\/p>\n

Fission – <\/strong>It is a type of asexual reproduction where the unicellular organism splits to form new organisms.\u00a0 There are two types of fission which are\u00a0<\/span><\/p>\n
