1
Aim: How does asexual reproduction result in offspring that are identical to the parent? Major Understanding In asexually reproducing organisms, all the genes come from a single parent. Asexually produced offspring are normally genetically identical to the parent
2
REPRODUCTION IN FLOWERING PLANTS Asexual Reproduction –Rhizomes –Tubers –Runners –Plantlets –Bulbs –Corms
3
Sexual Reproduction in the Plant Anther – pollen Stigma leads to ovary Fertilization results in the new seed
5
Asexual reproduction occurs in simple animals.. …Such as Jellyfish Flatworms Invertebrates Sponges Mitosis of the cells producing a new organism with the exact number and type of chromosome as the parent cell
6
Each cell is identical to the mother cell Artificially colored bacteria cells dividing by mitosis, as seen using a scanning electron microscope
7
Chromosome duplication Chromosomes can be seen when they double
8
DNA's Feat: Making Two Out of One
9
Two Strands Of The Same Chromosome Have Formed
10
Centrioles Chromatin Interphase Nuclear envelope Cytokinesis Nuclear envelope reforming Telophase Anaphase Individual chromosomes Metaphase Centriole Spindle Centriole Chromosomes (paired chromatids) Prophase Centromere Spindle forming Section 10-2 Go to Section: Moment in time during the process of mitosis
11
Mitosis Start with one cell End with two cells each with the exact number of chromosomes
12
Mitosis is asexual reproduction for the simplest organisms Amoeba
