1.	Question : Describe the life cycle of a flowering plant with a help of labelled diagrams.
Answer» Solution :(1) Adult plant produces flower : When the plant matures and is ready to reproduce, it develops flowers. Flowers are special structures involved in sexual reproduction , which includes POLLINATION and fertilisation. (2) Pollination : The transfer of pollen grains from the anther of a stamen to the stigma of a CARPEL is called pollination . (3) Fertilization : (i) After pollen grains falls on thestigma fertilization occurs when the male gamete present in pollen grains joins with the female gametes present in the ovule . (ii) In the ovary the makle gamete of pollen combines with the nucleus of female gamete or egg ptresent to form zygote. (4) Formation of fruit and seed : After fertilisation , a combined cell i.e. zygote grows into an embryo within a seed formed by the ovule. (5) Each seed contains a tiny plant called an embryo which has root , stem and LEAF parts ready to grow into a NEW plant when conditions are favourable . (6) Another part of the flower (the ovary ) grows to from fruit , which protects the seeds and helps them SPREAD away from the parent plant to continue the cycle .
