(i) This is a method known as asexual reproduction in which new plants may appear from older parts like stem, root, leaf etc. without seed formation. This is called as vegetative propagation.
(ii) Ginger, garlic, bryophyllum, banana etc.
(iii) (a) It takes less time to grow and bear flowers and fruits.
(b) New plants are exact copy of the parent plant.
(iv) Helping attitude towards her mother, curiosity to know scientific fact.

(a) Asexual reproduction is a type of reproduction in plants in which new plants are obtained from old ones without the production of seeds.
Two methods of asexual reproduction:
Vegetative Production, Spore Formation, Budding, Fragmentation (any two).
(b) Reproductive Parts of Flower:

Agent of pollination:
(i) Wind
(ii) Water
(iii) Animal i.e., insect, bird etc.

(a) A flower is the reproductive part of plant which helps in sexual reproduction.
A flower ensures the occurrence of process of fertilisation.
(b) Yes, flower aids in both pollination and fertilisation. Different colours and fragrance of flowers attract insects to them causing dispersal of pollen grain ensuring pollination.
Fertilisation occurs in the ovary of the flower after pollination of male and female parts.
(c) Number of some flowers can either have male or female parts on them, these flowers are called unisexual.
Some flowers have both, the male and female parts on them so they are called bisexual flowers.
(d) Ravi is aware, sincere, helpful as he helps others and knowledgeable while his sister is inquisitive, ready to acquire new knowledge and observant.

(a) Vegetative propagation is the process of reproduction in which new plants are produced from different parts of old plants like stem, roots or leaves.
(b) Cutting and grafting method are two methods where stem is used for vegetative propagation.
(c) Mango and rose are two plants cultivated using vegetative propagation.
This is an asexual method of reproduction.
(d) Ria is curious, inquiring who wants to gain knowledge about process occurring around here.

(a) The given figure is of ginger tuber.
(b) Asexual reproduction is seen in this plant.
(c) Ginger is a stem.
(d) Various parts of this plant can be shown as follows:

The method of seed dispersal in the fruits and the parts which help in the seed dispersal:

When the reproduction in an organism includes two types of gametes, i.e male and female from two different parents, it is called sexual reproduction, The sexual reproduction takes place by the fusion of male and female gametes by the process called fertilisation to form zygote.

Sexual reproduction (fertilisation) in plants The different steps that take place during sexual reproduction in plants are
(i) The pollens are deposited on stigma and begin to germinate.
(ii) Pollen tube containing male gametes reaches to the ovary of flower.
(iii) The tip of the pollen tubes gets dissolved and male gametes comes out of the pollen tube.
(iv) Inside the ovary male gametes fuse with the female gamete or egg present in the ovule.
(v) The fusion of both the gametes will result into a fertilised egg cell which is also called as zygote.

(a) The given figure shows grafting method (vegetative reproduction),
(b) Mango and rose are the two plants where this method of vegetative takes place,
(c) It is asexual method of reproduction,
(d) (A) Scion
     (B) Stock.

The various parts of a flower whose functions are mentioned above are labelled as follows:
