Science: Asexual VS Sexual Reproduction

Reproduction

The process of making new organisms

parent organism

They reproduce to make offspring

Genes

Pieces of DNA that affect an organism's traits

asexual reproduction

involves only one parent and produces offspring that are identical daughter organisms

binary fission

Asexual reproduction where one parent divides into two genetically identical organisms.

Budding

A small clone appears on one side of the organism, then detaches, becoming an individual

propagation

A piece of a plant breaks off, forms roots, and becomes a new plant

Spores

Unfertilized cells that don't grow until conditions are stable

Fragmentation

A new organism grows from the fragment of the parent and develops into a grown individual

sexual reproduction

2 parents produce offspring

Gamete

male and female sex cells,

ova (eggs)

Female gamete

Haploid

Carries only 1 copy of each chromosome

Sperm

male gamete

Diploid

During fertilization, sperm and egg unite to form a diploid

Zygote

fertilized egg

internal fertilization

Fertilization takes place internally

Meiosis

the process of making gametes

external fertilization

The female releases eggs, then the male releases sperm onto them

hermaphrodite

both male and female gametes

cross-pollination

occurs between 2 flowers

Gestation Period

time between conception and birth

Stamen

Male part of the flower

Pistil

Female part of the flower

Ovule

contains female gametes

Pollen

contains male gametes

Self-pollination

When the transfer is within the plant

Pollinators

bees, butterflies, birds, bats

What are the 5 methods of asexual reproduction?

binary fission, budding, fragmentation, propagation, spores
