1.	Question : What is flower ? Explain reproductive parts of flower and types of flowers on the basis of it.
Answer» Solution :Flower is the reproductive organ in flowering plants (angiosperms). Parts of a flower : Sepals, petals, stamens and pistils. Among these stamens and pistils are reproductive parts. Stamens : It is a male reproductive part. It consists filament and an anther. Anther produces pollen grains that are YELLOWISH in colour. Pistil : It is PRESENT in the centre of a flower and is the female reproductive part. It is made up of three parts : (1) Ovary : BOTTOM swollen part, (2) Style : middle elongated part and (3) Stigma : terminal sticky part. The ovary contains ovules and each ovule has an egg cell. Types of flowers on the basis of reproductive parts are as follows : (1) Unisexual flowers : When flower contains either stamens or pistil, it is called unisexual flower. e.g., PAPAYA, watermelon. (2) Bisexual flowers : When flower contains both stamens and pistil, it is called bisexual flowers. e.g., HIBISCUS, mustard, datura.
