$\;\qquad\quad\;\;\large{\odot\;\;\underline{\underline{\bf{\purple{Reproduction \; in\; plants}}}}}$

• Reproduction:- The process to produce of its own kind for the continuation of species is called as reproduction.

• Modes of Reproduction:- In plants, there are two types of reproduction: asexual and sexual.

*Note :: Refer Image for the flow chart and Text for Understanding it.

$\;\quad\quad\;\;:\mapsto\;\;\underbrace{\bf{\green{Asexual\; reproduction}}}$

In asexual reproduction, new plants are formed without the production of seeds or spores. It may be in following ways:

$\;\;\;:\rightarrow\;\;\underline{\bf{\orange{Vegetative \;propagation\;:-}}}$

In this type, the reproduction takes place through the vegetative parts of the plant, e.g.

• Stem in rose, sugarcane, potato, ginger, etc.

• Leaves in Bryophyllum.

• Roots in sweet potato and Dahlia.

$\;\;\;:\rightarrow\;\;\underline{\bf{\orange{Budding\;:-}}}$

The process of formation of an additional outgrowth which gets detach to produce an individual.

• Bud: The small bulb like projection coming out from the yeast is called a bud.

• The bud gradually grows and attains the shape of the parent and get detached from the parent cell to form a new yeast cell .

$\;\;\;:\rightarrow\;\;\underline{\bf{\orange{Fragmentation\;:-}}}$

Reproduction in alga is by fragmentation process . in this form of reproduction, an alga breaks up into two or more small pieces as fragments. These fragments grow into new individual.

$\;\;\;:\rightarrow\;\;\underline{\bf{\orange{Spore \; formation\;:-}}}$

the spores are asexual reproductive bodies . under favourable conditions a spore germinates and develop into a new individual . eg- fungi

$\;\quad\quad\;\;:\mapsto\;\;\underbrace{\bf{\green{Sexual\; reproduction}}}$

• Flowers are the reproductive organ of a plant .

• The stamens are the male reproductive part and the pistil is the female reproductive part.

$\;\;\;:\rightarrow\;\;\underline{\bf{\orange{Types \; of \; flower\;:-}}}$

• Unisexual flowers:- The flowers which contain either only the pistil or only the stamens in it, are called unisexual flowers, eg, corn, papaya and cucumber, etc.

• Bisexual flowers:- The flowers which contain both stamens and pistil in it , are called bisexual flowers, eg, mustard, rose, petunia, etc.

$\;\;\;:\rightarrow\;\;\underline{\bf{\orange{Types \; of \; gametes\;:-}}}$

• Male gametes :- anther of stamen contains pollen grains, which produce male gametes.

• Female gametes :- The ovary of a pistil contains one or more ovules. The female gamete or an egg is formed in an ovule .

• Pollination:- The transfer of pollen grain from the anther to the stigma of either the same flower different flower of same plant or different plants of same species is called pollination .

$\;\;\;:\rightarrow\;\;\underline{\bf{\orange{Types \; of \; pollination\;:-}}}$

• Self-pollination:- if the pollen reaches on the stigma of the same flower is called self pollination .

• Cross-pollination:- When the pollen of a flower reaches on the stigma reaches on the stigma of another flower of a the same plant or that of a different plant of the same species is called cross pollination .
