Sexual reproduction involves both parents. It serves as a source for speeding variations.  Angiosperic flowers consist of male reproductive part as stamens which carries male germ cells or pollens and female reproductive part as carpels. Carpel consists of stigma, style and ovary which have ovules. Pollens are transferred to stigma by a process known as pollination and fuses to form zygote which further forms embryo. This fusion process is termed as fertilization. Tutorspoint provides Sexual Reproduction in Floweering Plants Homework Help for college and university students.

Sexual Reproduction in Floweering Plants Homework Help

Sexual reproduction is a mode of reproduction involving both male and female. DNA copies from both parents combine together to give rise to a new individual. Sexual reproduction is important because it acts as a source of variations. Combining two DNA copies broadens the chances to incorporate variations. In a way it speeds up the variation process.

Sexual reproduction is a complex process in which reproductive cells known as germ cells carries half the amount of DNA and chromosome number as compare to cells not taking part in reproduction. Sexual reproduction generally involves small and motile male germ cells and non motile large female germ cells for food storage to provide energy for developing zygote.

Reproductive parts of angiosperms

Angiosperms have their reproductive parts located in flowers. Flower consists of four main parts as sepals, petals, stamens and carpels

Stamens are male reproductive part where as carpels serves as female reproductive part. Presence of either stamens or carpel makes a flower unisexual e.g. papaya where as in bisexual flowers both stamens and carpels are presente.g. mustard

Female reproductive part

Carpel consists of three parts as stigma, style and ovary 

Ovary: - Lower enlarged part of carpel which contains ovules which in turn contains egg cells.

Stigma: - Terminal sticky region where pollen attaches.

Style:- Middle tube like structure


Male reproductive part

Stamens consist of lobe like structure known as anther which has male germ cells known aspollens.

Processof transfer of pollens on to stigma is known aspollination. Pollination occurred on same flower is referred asself-pollination where as if occurred between two flowers with the help of agents like wind, insect etc is knownas cross-pollination.


Pollen after reaching stigma extends a tube like structure which helps transferring pollens to the ovary where male and female germ cells fuses to form azygote. This fusion process is known as fertilization. Zygote thus formed give rise toembryo inside ovule by several divisions. Ovule is the future seeds where as ovary is the future fruit. On meeting favorable conditions embryo give rise to seedlings. This process is termed asgermination
