The parts in the given figure are labelled as follows

(a) Unisexual flowers are papaya, cucumber, corn.
(b) Bisexual flowers are rose, mustard, lady's finger, Petunia, pea.
(c) Unisexual flowers are also called as incomplete flower while bisexual flowers are called hermaphrodite or complete flowers.

The steps involved in the process of fertilisation are
(i) After pollination, pollen grains start growing into a pollen tube on the stigma passing through pistil.
(ii) The tube extends through the style and reaches to the ovules.
(iii) The pollen tube carries the male gametes called pollen grains.
(iv) Male gametes fuse with the egg (female gamete) present inside ovule and forms a zygote. This process is called fertilisation.
(v) Later zygote develops into an embryo and ovules develop into a seed.
(vi) Thus, seed carries an embryo with stored food and is covered by a hard protective covering called seed coat.

The differences between self-pollination and cross-pollination are

The main differences between asexual and sexual reproduction are

Bryophylum can reproduce by its leaves.

A spore-producing plant is bread mould.

Mature ovary forms the fruit.

The process of fusion of the male and the female gametes is called fertilisation.

The reproductive part of a plant is the flower.

Branch can be used to grow a new rose plant. As, rose reproduces by vegetative propagation, i.e. stem cutting method.

Flowers are so colourful because they absorb and reflect light energy. Fragrance results from production of volatile chemicals which evaporate.

Unisexual flowers are those which contain either male or female reproductive part and bisexual flower has both reproductive parts (i.e. male and female) on the same flower.

The odd one out is rice.
In the above given pairs as rice reproduces by sexual reproduction and sugarcane, potato and rose reproduce vegetatively.

(a) Spirogyra - fragmentation
(b) Yeast - budding
(c) Money plant - Vegetative propagation.

The four main parts of a flower are
(i) Sepals
(ii) Petals
(iii) Stamen
(iv) Pistil.

Fungus, moss and fern reproduce by the common method of spore formation which is a type of asexual reproduction.

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.
