Types of Reproduction in Living Organisms: A Comparison of Asexual and Sexual Reproduction, Study notes of Genetics
An overview of two primary types of reproduction in living organisms: asexual and sexual. Asexual reproduction involves the production of offspring from a single parent, resulting in genetically identical organisms. Sexual reproduction, on the other hand, requires two parents and results in offspring with a unique genetic makeup. various forms of asexual reproduction, including mitosis, bacterial binary fission, vegetative reproduction, budding, fragmentation, and regeneration. It also discusses sexual reproduction, its advantages and disadvantages, and various examples of organisms that reproduce sexually.

Binary fission is a form of asexual reproduction where every organelle is copied and the organism divides in two.
Asexual Reproduction
Budding

Budding is a means of asexual reproduction whereby a new individual develops from an outgrowth of a parent, splits off, and lives independently.

Regeneration occurs when a body part has broken off and the organism grows a new one.

Plant Kingdom
Flowers are the reproductive organs of plants.
Some flowers have both male and female reproductive
organs on the same flower.
Male flower Female flower
Sexual Reproduction
Happens 2 ways
Internally (inside)
The egg is fertilized by sperm inside the female
Mammals, birds, reptiles, insects, spiders
Externally (outside)
The egg is fertilized by sperm outside the female
The female lays the eggs and then the male fertilizes
them.
Fish and some amphibians Plants and fungi (pollen and spores)
