Sexual and Asexual Reproduction.
Asexual Reproduction: • One parent producing an offspring identical to itself (parent) • Offspring can live independently
Cell Division in Unicellular Organisms Binary Fission: • form of asexual reproduction in prokaryotic (lacks nucleus) organisms • Parent organism splits in half (Eukaryotic – reproduce by mitosis ex: algae, some yeast, protozoans like paramecium)
Budding • Organism develops tiny buds on its body • Asexual reproduction • Buds form from the parent cell so the bud is identical to the parent. • Both unicellular and multicellular • Examples: hydra, plants, some yeast
Regeneration: • Specialized cells grow new tissue when a wound or lost limb occurs • Examples: Starfish, lizard tails, planarian, cuttings from plants….
Asexual Reproduction & Health – Bacteria reproduces at very rapid rates – Reason you get sick within a day. .
• Spore Formation – spores = small specialized cells that contain a nucleus and cytoplasm surrounded by a thick outside wall which protects the spore. Under the right conditions the spore can rise to a new organism. Found in bacteria, molds, yeast, mushrooms, mosses, ferns and some protozoans.
Sexual Reproduction • Two parents egg (female) and sperm (male) • Fertilization – when egg and sperm unite • Plants growing from seeds and animals growing from eggs • Creates the diversity of life on earth • Offspring is unique
Asexual Reproduction • • One parent Identical to parent More likely to get disease Binary Fission, budding, regeneration, spore formation
Sexual Reproduction • • • Two parents – male and female Unique offspring ( not identical to parents) Egg, sperm Fertilization ( egg and sperm unite) More resistant to disease
