Reproduction
Sexual
Sexual reproduction involves the uniting of gametes ,which are reproductive cells to make a new organism.
Asexual
Asexual reproduction requires one organism and results in a offspring that are genetically identical.
Spore formation
is the process of production of spores or reproduction via spores. Spores are asexual reproductive bodies. Under favourable conditions, a spore germinates and develops into a new individual.
The bread mould undergoes asexual reproduction using spores. Hence, fungus is seen on the bread. The dispersed spores fall on the bread's surface. As desirable conditions are obtained, they germinate and reproduce.

Parthenogenesis
Parthenogenesis is a type of asexual reproduction in which a female gamete or egg cell develops into an individual without fertilization.
In honeybee colonies, the fertilized eggs become females, and the unfertilized eggs will develop into male drones. This is a process known as haploid parthenogenesis: the unfertilized egg has only half the number of chromosomes of a fertilized egg. .These eggs are not fertilized, and will produce only male honeybees.
Vegetative propagation
Vegetative propagation is an asexual method of plant reproduction that occurs in its leaves, roots and stem. This can occur through fragmentation and regeneration of specific vegetative parts of plants.

Fragmentation
Fragmentation, the splitting of cells into two parts and makes new bodies is known as fragmentation. Each fragment develops into a mature clone genetically and morphologically identical to its parent.
Fragmentation is observed in nonvascular plants as well, for example, in liverworts and mosses. Small pieces of moss "stems" or "leaves" are often scattered by the wind, water or animals. If a moss fragment reaches a suitable environment, it can establish a new plant.
Binary fission
Binary fission, asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism duplicates its genetic material and then divides into two parts with each new organism receiving one copy of DNA.
Euglena reproduce asexually through binary fission, a form of cell division. Reproduction begins with the mitosis of the cell nucleus, followed by the division of the cell itself.
