Slide 1 - Video
Mitosis:
The daughter cells are an exact copy of the mother cell.
Interphase - the cell is at rest and is already copying the chromosomes.
Prophase - the step before mitosis the nucleus is still there
Metaphase - the chromosomes move to the middle of the nucleus.
Anaphase - the chromosomes split and the separate chromosomes move away from each other.
Telophase - the separated chromosomes form two new nuclei at each end of the cell.

Is used to create gametes.
PMAT is done twice!
Prophase - the step before mitosis the nucleus is still there
Metaphase - the chromosomes move to the middle of the nucleus.

Sexual Reproduction in Animals
Most animals that have sexual reproduction have 3 phases:
Pre-Fertilisation (the gametes also known as sex cells are produced and prepared).
Fertilisation (the sex cells are brought together somehow and melt together to form on cell "zygote").
Post-Fertilisation (the zygote start dividing by mitosis and becomes and embryo which continues to grow).

Asexual Reproduction in Animals
Some very small animals are so small they can reproduce by mitosis.
A hydra can reproduce by budding, many species of jellyfish reproduce this way too.
Some animals can reproduce by means of fragmentation. This means that they can break off a piece of themselves and a whole new organisms can grow from that piece. Flatworms, starfish and seasponges can do this.
