Seksuell reproduksjon krev eit egg frå ho og sædceller frå han for å danna avkom i mora sin mage. Dette inneber ein prosess der foreldrecelle deler seg for å bli to. I virveldyr skjer befruktninga ved at gametar smeltar saman til ein zygote, som utviklar seg til foster.
Every individual organism is the offspring of a reproduction
Reproduction
Plants sexual reproduction
It is almost the same only that some things change like the sperm because it changes for pollen, but the rest everything happens as in vertebrates
Fertilization process in vertebrates
Fetal development
Zygote Division
Zygote (fertilized egg)
Gametes
In sexual reproduction, a female egg and a seed that comes from the father is needed so that the offspring are formed in their mother's womb.
Sexual Reproduction
No offspring is identical to parents
Fertilization and gametes if included
Two parental cells
Genetically different from their parents
Vs
Asexual Reproduction
All the offspring will be totally the same
Fertilization and gametes are not included
One parental cell
Identical offspring to his mother
How is it ?
What is needed for this is the following is a parental cell, to be able to divide and thus become two
Types of Asexual reproduction
Parthenogenesis
What happens is that female organisms produce an egg without their egg being fertilized
Fragmentation
They are divided into three: the head, the tail and the trunk.
From there other worms will come out that also split between three
Budding
What happens is very simple, the offspring grow on top of the adults so that the adults remain below and the offspring remain above
Spores
The spores are like a powder that the ferns generate to reproduce so that the powder hangs below the fern leaves, so when their time to leave they become many because in reality there were millions of cells in a heap, then they are propelled with the air or if they fall into the water they help each other to reach the ground to plant themselves there
Binary Fission
It is called binary fusion because it duplicates your DNA to split in two with the same DNA
