The evolutionary success of higher plants relies on a very pithy gametophytic phase, which underlies the sexual reproduction cycle.

Sexual put reproduction takes place in staunch organs of the flower: pollen, the male gametophyte, is released from the anthers and next adheres, grows and interacts forth various tissues of the woman organs, collectively known as the pistil. Finally, it fertilizes the female gametophyte, the embryo pouch. Pollen is released as bi or tricellular, highly de-hydrated with presumably containing all the biochemical components and transcripts to take root.

Upon hydration on the woman tissues, it develops a cytoplasmic extension, the pollen tube, which is one of the fastest growing cells in nature. Pollen is completely "ready-to-go", but ignoring this seemingly simple reaction, jolly complex interactions take place by way of the female tissues.

In privileged animals, genetic mechanisms for mating determination establish striking developmental differences between males and females. Feature in contrast, most higher plant order develop both male and woman structures within the same floret, allowing self-fertilization. Outcrossing is ensured by self-incompatibility mechanisms, which evolved under precise genetic control, controlling self-recognition and cell-to-cell interaction.

Plants have developed various strategies, both sexual and asexual, to ensure reproductive success. Plants have evolved different reproductive strategies for the continuation of their species. Some plants reproduce sexually while others reproduce asexually, in contrast to animal species, which rely almost exclusively on sexual reproduction.
About ME: My name is Carmen, 27 years old from Baltimore: My favorite movie "Monika (1974 film)" and favorite book about sex "A Spy in the House of Love".

Sexually are reproducing of gametophytes flowering plants Plant reproduction is the production of new offspring in plants , which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes , resulting in offspring genetically different from the parent or parents. Asexual reproduction produces new individuals without the fusion of gametes, genetically identical to the parent plants and each other, except when mutations occur. In seed plants , the offspring can be packaged in a protective seed , which is used as an agent of dispersal. Reproduction in which male and female gametes do not fuse, as they do in sexual reproduction. Asexual reproduction may occur through budding , fragmentation , fission , spore formation and vegetative propagation. Plants have two main types of asexual reproduction in which new plants are produced that are genetically identical clones of the parent individual.
