How do organisms reproduce?

Reproduction

Biological process by which organisms produce new individuals of their own kind.

Why is reproduction imp?

Ensures continuity of species and include variation.

What is DNA copying?

Process during reproduction that passes genetic information to offspring with small variation.

Asexual reproduction

Reproduction involving a single parent within fusion of gametes.

Main feature of asexual reproduction

Offspring are genetically identical to parent.

Binary Fission

Offspring are genetically identical to parent.

Example of binary fission

Amoeba, bacteria

What is multiple fission?

One organism divides into many daughter cell at one.

Example of multiple fission

Plasmodium

Budding

New organism develop from a bud on the parent body.

Example of budding

Yeast

What is fragmentation?

Body breaks into pieces and each grows into a new organism.

Example of fragmentation

Spirogyra

What is regeneration

Ability to regrow loss body parts into new organism.

Example of regeneration

Planaria

Sexual reproduction

Reproduction involving fusion of male and female gametes.

Zygote

Cell formed after fusion of gametes.

Why is sexual reproduction imp?

Producers variation necessary for evolution.

Male part of flower?

Stamen

Female part of flower

Pistol of carpel

Pollination

Transfer of pollen from anther to stigma.

Types of pollination

Self pollination and cross pollination

Fertilization in plants

Fusion of male and female gametes in ovule.

What happens after fertilization?

Formation of embryo and seed.
