  2. *Reproduction* • We’lldiscover: • Whatheredityis. • Types of traits and howthey are passedtooffspring. • Fertilization. • Types of reproduction.

  3. Heredity • It’sthepassing of traitsfromtheirparentstotheiroffspring. • There are twotypes of traits: • Learnedtraits: theonesthat are notpassedfromparents. • Inheritedtraits: theonesoffspringreceivefromtheirparents.

  4. Sexual Reproduction • Reproductionbytwoparents. • Theprocess in whichthecells divide and sex cells are formediscalled meiosis. • Themale sex cellisthesperm. • Thefemale sex cellistheeggcell. • Fertilizationistheprocess in whichthesperm and theeggcells are unitedforming a zygote.

  6. AsexualReproduction • Reproductionbyoneparent. • Offspringshavethesame DNA as theparent. • Cells produce asexuallyby mitosis. • Someplants reproduce by a processcalledbudding. • Formingsporesisanothertype of asexual reproduction. • Producingoffspringfrom a piece of theparent.

  9. THE WHOLE PROCESS

  10. Meiosis Process in which sex cells are formed.

  11. Mitosis Process in whichcells divide receivingeachonetheexactnumber of chromosomepairs.

  12. Comparing Sexual And Asexual Reproduction Asexual: - Ithappensquickly, requireslessenergy, needsjustoneparent, produces offspringwithidentical DNA totheparent. Sexual: - Itis a slowprocess, requires more energy, needstwoparents, produces offspring withunique DNA.

  13. Welearnt: • How and howlong asexual reproductionbybudsis. • Howspores reproduce in strawberries and a piece • of bread. • Howtoinvestigate in ourbooks and the internet • theprocess of meiosis and mitosis.
