Where Life Comes FromWhere Life Comes From Spontaneous Generation

Idea that living things come from non-living things. Your DNA contains the information needed to

make a human with your characteristics or traits.

Living things reproduce and pass on exact copies of their DNA to offspring.

Reproduction in animals and plants usually involve two parents.

DiversityRange of differences found among members of a

population.

ReproductionReproduction Meiosis

Each new cell divides again, gametes form by a division of the nucleus.

MitosisEach new cell has exact copy of the

chromosomes that were in the parent cell. Asexual reproduction=1 parent Sexual reproduction=2 parents External fertilization

Fertilized outside the female body Internal fertilization

male places sperm inside female body causing fertilization.

New Animal begins as a zygoteBecomes an embryo

which is made of a million different cells

Embryo eventually takes on different shapes and functions this is called cell differentiation.

Mammal OffspringMammal Offspring

Produce few offspringTake care of young for long periods of timeMost carry young inside their body.

Embryo is held and protected by the Uterus.Placenta provides food & oxygen from mother

to developing embryo.Different Mammals have different gestation

times depending on size.(Time till birth)
