Reproduction
The process by which organisms give rise to offspring
Asexual Reproduction
Sexual Reproduction
• parent reproduces by itself• offspring is genetically identical to “mamma”
It takes two baby ….
+
•Offspring is genetically unique• creates diversity w/in population
1) Mitosis 2) Binary Fission3) Budding4) Spores5) Regeneration6) Vegetative Propagation
Asexual Reproduction
produce 2 identical daughter cells with the same # of chromosomes as the parent cell. (identical)
1) Mitosis 2) Binary Fission
• a parent cell splits into 2 daughter cells of = size
• w/ prokaryotes
3) Budding
4) Spores
• a new, duplicate organism forms at the side of the parent and enlarges until an individual is created.
• spores are surrounded by a tough coat to help them survive harsh conditions. .. Produced and released
5) Regeneratio
n
6) Vegetative Propagatio
n
• growth of new tissues/organs to replace those injured or lost.
• Common in invertebrates, especially Asteroidea (Sea Stars) and Annelida (Worms).
* In some multicellular plants * new plants develop from the
roots, stems, or leaves of the parent.

Sexual Reproduction
1) Meiosis
Which we’ll go into much detail later on …. But here’s the bare bone basics…..
Diploid – total # … 2n
Haploid– ½ the # …n
+
fertilization
haploidhaploid
• Somatic cells .. Normal cells … nerve,etc
•Sex cells… GAMETES … sperm/egg
