1. Two Types of Reproduction

2. Asexual Reproduction used by some plant and invertebrate species
requires 1 parent
offspring are genetically identical to the parent
uses body cells

3. Body Cells called somatic cells (somato- means “body”)
body cells are diploid = contain 2
sets (pairs) of chromosomes
(diplo- means “double”)
made by the process of mitosis throughout the entire body

4. Steps of Asexual Reproduction
Body cells are made by mitosis

5. Steps of Asexual Reproduction
The organism undergoes binary fission, budding or regeneration to create an offspring

6. Sexual Reproduction used by most species requires 2 parents
offspring are genetically different from the parents
uses sex cells

7. Sex Cells called gametes = egg and sperm cells
(gamo- means “sex cell”)
sex cells are haploid = contain 1
set (single) of chromosomes
(haplo- means “single”)
made by the process of meiosis
inside reproductive organs

8. Steps of Sexual Reproduction
Sex cells are made by meiosis
(like “double mitosis”)
Cells divide twice

9. Steps of Sexual Reproduction
Male & female sex cells come together to form one body cell (called a zygote)
Cell from mom
Cell from dad
zygote

10. Steps of Sexual Reproduction
The zygote undergoes mitosis repeatedly until it develops into a complete organism
Etc…

11. Mitosis made my-TOES-es
Memory Phrase
Meosis made ME-osis
Mitosis made my-TOES-es
