TYPES OF REPRODUCTION ASEXUAL VS SEXUAL

Let’s do some comparing! Prokaryote/Eukaryote? Unicellular/Multicellular? Heterotroph/Autotroph? Asexual/Sexual? Eukaryote, Multicellular, Heterotroph, Sexual Eukaryote, Unicellular,

PRE-TEST: TRUE OR FALSE? 1. Cells in the bodies of multicelled creatures, such as

PRE-TEST: TRUE OR FALSE? 1. Cells in the bodies of multicelled creatures, such as humans, are reproduced in a way that is very similar to the method used by most protozoa. _____ 2. All human cells have two complete sets of chromosomes. _____ 3. In biology, fertilization is when one cell divides into two cells. _____ 4. Inside of cells, nearly all the genes are located on special structures known as microtubules. _____ 5. Cell growth takes place during the stage of a cell's life cycle known as interphase. _____

ASEXUAL REPRODUCTION • All genetic information from 1 parent –Therefore, have same DNA as

ASEXUAL REPRODUCTION • All genetic information from 1 parent –Therefore, have same DNA as parent • Results in clones (genetically identical orgs. )

TYPES OF ASEXUAL REPRODUCTION • BINARY FISSION – Cell simply divides in half –

TYPES OF ASEXUAL REPRODUCTION • BINARY FISSION – Cell simply divides in half – DNA copies itself and then cell divides – results in 2 genetically identical cells • EX: Bacteria, Protists

TYPES OF ASEXUAL REPRODUCTION • BUDDING – NUCLEUS (CONTAINING DNA) DIVIDES EQUALLY – CYTOPLASM

TYPES OF ASEXUAL REPRODUCTION • BUDDING – NUCLEUS (CONTAINING DNA) DIVIDES EQUALLY – CYTOPLASM DOES NOT – THEREFORE, RESULTS IN “BUDS” • EX: YEAST, HYDRA

TYPES OF ASEXUAL REPRODUCTION • SPORULATION – “SPORE FORMATION” – SPECIALIZED SINGLE CELLS COMING

TYPES OF ASEXUAL REPRODUCTION • SPORULATION – “SPORE FORMATION” – SPECIALIZED SINGLE CELLS COMING FROM ONE PARENT • EX: OCCURS IN MOLD AND OTHER FUNGI

SEXUAL REPRODUCTION • TWO PARENTS • HALF (1/2) GENETIC INFO FROM EACH PARENT –

SEXUAL REPRODUCTION • TWO PARENTS • HALF (1/2) GENETIC INFO FROM EACH PARENT – THEREFORE, OFFSPRING GENETICALLY DIFFERENT FROM PARENTS • GENETIC VARIATION!!!!! – SHARE SOME SIMILARITIES • GAMETES (SEX CELLS) EACH CARRY A HALF OF THE INFO

SEXUAL REPRODUCTION • FERTILIZATION: – THE JOINING OF SEX CELLS ½ genetic (egg) +

SEXUAL REPRODUCTION • FERTILIZATION: – THE JOINING OF SEX CELLS ½ genetic (egg) + ½ genetic (sperm) = 1 genetically whole organism

POST QUIZ: TRUE OR FALSE? 1. Diploid cells have two full sets of chromosomes.

POST QUIZ: TRUE OR FALSE? 1. Diploid cells have two full sets of chromosomes. _____ 2. DNA replication takes place during the metaphase stage of mitosis. _____ 3. Chromosomes are not visible during most of a cell's life cycle. _____ 4. Asexual reproduction requires only one parent. _____ 5. Meiosis does not occur in most types of cells. _____
