1 B SMART

2 Asexual\Sexual Reproduction
Lets talk about sex . . . Asexual\Sexual Reproduction

3 Reproduction Asexual Reproduction Sexual Reproduction
The process by which organisms give rise to offspring Asexual Reproduction Sexual Reproduction It takes two baby …. parent reproduces by itself offspring is genetically identical to “mamma” + Offspring is genetically unique creates diversity w/in population

4 Asexual Reproduction Mitosis Binary Fission Budding Spores
Regeneration Vegetative Propagation

5 1) Mitosis 2) Binary Fission
a parent cell splits into 2 daughter cells of = size w/ prokaryotes produce 2 identical daughter cells with the same # of chromosomes as the parent cell. (identical)

6 3) Budding 4) Spores spores are surrounded by a tough coat to help them survive harsh conditions. .. Produced and released a new, duplicate organism forms at the side of the parent and enlarges until an individual is created.

7 6) Vegetative Propagation
5) Regeneration 6) Vegetative Propagation stolons 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.

8 Sexual Reproduction Meiosis
Which we’ll go into much detail later on …. But here’s the bare bone basics…..

9 + Diploid – total # … 2n Haploid– ½ the # …n haploid haploid
fertilization Somatic cells .. Normal cells … nerve,etc Sex cells… GAMETES … sperm/egg

10 46 46 + 23 23 haploid haploid fertilization 46
