Objective: Using “asexual and sexual reproduction,” I can identify the advantages and disadvantages of each based on the number of parents and how that affects the inheritance of traits.
Learning Standard: LS -9 compare sexual and asexual reproduction
Types of Asexual Reproduction
Single celled organism divides its cytoplasm and nucleus to form two identical organisms
Parent divides its nucleus equally but cytoplasm unequally. Offspring grows and breaks off from parent.
Specialized single cells are released from one parent and grow by cell division (mitosis)
The process by which certain cells produce new tissue growth at the site of a wound or lost limb.
A single parent breaks into parts that regenerate into whole new individuals.
Occurs in all members of the animal kingdom:
Flowers are the reproductive organs of plants
Some flowers have both male and female reproductive organs on the same flower.
Happens 2 ways
The egg is fertilized by sperm inside the female
– Mammals, birds, reptiles, insects, spiders
The egg is fertilized by sperm outside the female
The female lays the eggs and then the male fertilizes them.
– Fish and some amphibians
Examples of organisms that reproduce sexually
– Chickens – Iguanas – Lobsters – Sharks
– Humans – Butterflies – Sunflowers – Roses
