Study Notes

Bread mold and some invertebrate animals reproduce asexually.
Asexual reproduction in animals includes budding and regeneration.
Budding is a method of reproduction where a new organism grows from a parent's body and can either stay attached or break off.
Regeneration is the process where detached body parts of an organism can develop into a new organism if they contain enough genetic information.
Asexual reproduction is advantageous for organisms that stay in one place and have stable environments.
Sexual reproduction involves the fusion of two gametes from both parents, forming a diploid organism.
Sexual reproduction in algae includes conjugation and alternation of generations.
Internal fertilization occurs when eggs are fertilized inside the female's body and new offspring develop outside of it.
External fertilization occurs when eggs are fertilized outside the female's body.
Hermaphrodites are animals that have both female and male reproductive organs but may still require a mate to reproduce.
Parthenogenesis is a process where eggs develop without fertilization.
Plants reproduce from a seed which grows into a plant and sheds seeds to continue the cycle.
Mammals give birth to live young and feed them with milk, while other animals lay eggs.
The reproductive system of a flower includes carpels (female reproductive organs) and stamens (male reproductive organs).
In the flower's carpels, the ovary is where the eggs are produced, and the style and stigma facilitate the transfer of male gametes to the ovary.
