A
2
B
1
C
3
D
4
Explanation: 

Detailed explanation-1: -Sexual reproduction requires two parents. Each parent contributes a gamete-a sex cell that has half of the normal DNA of a regular body cell. In males, the gametes are sperm and in females, the gametes are eggs.

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

Detailed explanation-3: -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-4: -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-5: -Asexual reproduction does not involve sex cells or fertilisation . Only one parent is required, unlike sexual reproduction which needs two parents. Since there is only one parent, there is no fusion of gametes and no mixing of genetic information.
