Reproduction

The process by which organisms produce offspring

Reproduction

The Big Question (aka GSE)

How are sexual and asexual reproduction the same and how are they different?

Types of Reproduction

Sexual: Two parents have offspring; offspring share traits from both parents.

Asexual: One parent has

offspring; offspring are genetically identical to parent.

Sexual Reproduction

Animals: Female parent produces an ovum, male parent produces a sperm. Both combine to produce an offspring, with genetic material from each parent.

Plants: Female part of the plant produces an ovum, male part of the plant produces pollen. Both combine to produce an offspring, with genetic material from each parent.

Asexual Reproduction

Binary Fission: The process by which the organism splits into two.

Most bacteria and protozoa reproduce by binary fission.

Asexual Reproduction

Budding: an offspring grows out of the body of the parent.

Hydra and sponges reproduce by budding.

Vegetative Propagation

The production of a new organism from a portion of another organism

Plants can reproduce by vegetative propagation

Regeneration

The re-growth of a lost or damaged part of an organism

Starfish can regenerate an arm Planaria can regenerate into two

organisms

Reproduction

What is it? The process by which organisms
