Asexual ReproductionRequires only one parentOffspring have 100% the same chromosomes
as the parent. Same exact DNA as parents!In other words, the offspring are exact “clones”
of the parent.Most one celled organisms reproduce this way.MitosisMovie

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

Plant cuttings
Vegetative reproduction is a type of asexual reproduction in plants that relies on multi-cellular structures formed by the parent plant. It has long been exploited in horticulture and agriculture, with various methods employed to multiply stocks of plants.

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

Fragmentation
Fragmentation is a means of asexual reproduction whereby a single parent breaks into parts that regenerate into whole new individuals.

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

Sexual ReproductionRequires two parents that each contribute
½ of the genetic information. ( ½ from sperm ; ½ from egg )
Offspring share the characteristics of each parent. Offspring is a mix of parents DNA!
This results in genetic diversity (differences)

Sexual ReproductionPlant 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 ReproductionHappens 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)
