sexual and asexual reproduction in plats

• Asexual reproduction is the reproduction of new plants from one parent only. The offspring is genetically identical to the parent plants because no combination of gametes through fertilization happened.

  It can be classified into two; Apomixis and Vegetative Propagation
• Regeneration - is the development of the separated plant parts into new individuals.
• Fragmentation - is the separation of plant parts from the parent plant.
• Natural vegetative propagation – refers to the development of a new plant from leaves, roots, or stems of a mature plant.
• Apomixis - is a type of asexual reproduction that occurs when seeds are produced without fertilization by pollen grains. It is also called parthenogenesis (virgin birth). In this process, embryo sac develops within ovule but it does not undergo double fertilization. Instead, the egg cell inside the embryo sac will directly form an embryo without being fertilized by sperm cells.
• Artificial vegetative propagation - It is an asexual reproduction requires human intervention. Tissue culture, grafting and stem cutting are all artificial methods of vegetative propagation.
• Sexual reproduction in plants takes place sexually and asexually as well. But the majority of the flowering plants reproduce sexually. The flower is the reproductive part of a plant i.e., both male (stamen) and female gametes (pistil) are produced by flowers. Sexual reproduction in plants takes place in flowers.
• Pollination - is the process of transferring pollen grains from the anther – male part of a flower, to the stigma – female part of a flower. In order to form zygote or the fertilized egg
• Self-pollination - A pollination where the pollen transfer takes place between the anther and stigma of the same flower.
• Cross Pollination - A pollination where the pollen transfer takes place between different flowers on the same plant or between two different plants of the same species. This can be achieved through wind or insects.
• Cross-pollination - A pollination where the pollen transfer takes place between the anther and the stigma of different flowers of the same plant or different plants of the same species.
