Answer 2

hello friend....!!

A ) UNISEXUAL FLOWERS AND BISEXUAL FLOWERS

⇒ the flower that bear both stamen ( male sex organ in flower) and pistil (female sex organ) in a same flower is called a bisexual flower .

⇒some flowers bear either a stamen or a pistil , such flower that has only one sex organ either male or female is called a unisexual flower.

B) ASEXUAL AND SEXUAL REPRODUCTION 

⇒ the mode of reproduction that does not involve the formation of gametes, involves the participication of a single parent is called asexual reproduction Example: vegetative propagation ,

⇒ in sexual reproduction the male and the female gamete fuse together to form the zygote. Eample : reproduction in flowering plants , humans.

C) SELF POLLINATION AND CROSS POLLINATION 

⇒ when the pollen grains are transferred from the stamen to the stigma of the same flower then it is called self pollination.

⇒ if the pollen grains are transferred from the stamen of one flower to the stigma of the another flower then the process is called cross- pollination.
