Aside from fun, sex is good for introducing variability. Asexual, clonal, reproduction leads to exact copies of the parent. If the environment was always exactly the same, and if there were not pathogens trying to overcome the defenses of organisms, that might work out very well, and be very efficient. However, the creation of new combinations of genes that results from sexual reproduction results in novel forms, that may be more adapted to the unpredictable future, and may not be as susceptible to those pathogens that have come up with a way to attack other members of the species.
Greater Variation therefore a stronger species
IN SEXUAL REPRODUCTIONoffspring are produced by fusion of two different sex cells and they form a cell called zygote so there is transfer of different genes to the offspringwhich results in differentiation or it enables us differentiate among us while in asexual reproduction daughters are produced by a small part like cutting, grafting, etc and in animal like budding, binary fusion so it is not easy to differentiate.
That would be sexual reproduction. Sexual reproduction allows for independent assortment and crossing over to occur. This is fancy language for the genetic material gets mixed up a lot. Since the genetic material gets mixed up, variation will result.
Variations occurs in species due to the process of "Crossing over"
First, it should be noted that the development of gender (sexual dimorphism) is a subject separate from that of the evolution of sexual reproduction. Sexual reproduction had already existed for a long time when the first sexually dimorphic species evolved. Sexual dimorphism, gender, is the situation wherein there exist distinct roles in the reproductive cycle, and morphologies associated with each role have diverged. One way that sexual dimorphism could have evolved is through the difference in size an number between male and female gametes. Males are typically able to produce gametes in prodigious numbers, while females usually produce far fewer and larger gametes. This makes males more redundant, in some cases leading to male competition over females, while females may have the "luxury" of "picking and choosing" from the redundantly available males. A difference in gender roles and associated morphology may follow from this. This is one way for gender and sexual dimorphism to evolve, but not the only way.
Sexually-reproducing species have an advantage over asexually-reproducing species in their ability to use two different sex cells.
Variability of offspring.

It is generally though that sexual recombination is the greatest advantage of sexual reproduction over asexual reproduction. By recombining genes you get many variants that may have some members of the population resistant to some environmental challenge. Asexuality just gives clones.

You will be able to get the genes from both sets of parents. This allows for adaptation and evolution to occur over time.
This is because asexual reproduction selects genes thus reducing the alleles, the gene pool, if done over and over. Sexual reproduction selects genes randomly thus preserving the gene pool. Hope this helps! :)

Some organisms can use both types of reproduction. For example, when conditions are favorable, many plants and fungi will reproduce asexually. Doing so lets them spread quickly and take over an area. When the environment changes these organisms will switch to sexual reproduction. this strategy increase the chance that the species will survive.
Sexual reproduction
Asexual reproduction is only done by cells, plants, and a few protozoa. Sexual reproduction is the only choice humans have and it has quite a few advantages over asexual reproduction. It results in more variation and is more fun.
For creatures whose primary reproductive strategy is to produce a huge numbers of copies, such as bacteria, sexual reproduction isn't as viable. The main advantage would be speed in which new individuals are generated perhaps, whereas a huge disadvantage is that the genepool of species is kept relatively poor in terms of variablilty.
