Detailed explanation-2: -In sexual reproduction, two parents contribute genetic information to produce unique offspring.

Detailed explanation-3: -Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. Sexual reproduction involves two parents and produces offspring that are genetically unique.

Detailed explanation-4: -Sexual reproduction requires genetic material ( DNA ) from two parents. The parent plants have male and female sex cells, called gametes. The genetic material from the male and female gametes combines to produce offspring.

Detailed explanation-5: -The offspring inherit a mixture of genes from both parents, so are different to each other and their parents. The advantages of sexual reproduction: produces genetic variation in the offspring. the species can adapt to new environments due to variation, which gives them a survival advantage.
