2. Why is reproduction important? Is a process that creates new offspring. DNA or genes are passed from one generation to the next. Reproduction helps populations grow. Reproduction reduces the chances of species becoming extinct.

3. There are two types of reproduction: Sexual and Asexual SEXUAL REPRODUCTION: requires both a male and a female. The DNA of the offspring is a combination of both parents. Examples: humans, dogs, birds, some plants. ASEXUAL REPRODUCTION: only involves one organism. The organism makes an identical copy of itself, or a clone. Examples: Bacteria, some plants, protists.

4. Comparison Chart : Characteristics: AsexualSexual Number of organisms involved One parent neededTwo parents are required to mate AdvantagesTime Efficient; no need to search for mate, requires less energy Variation, Unique., organism is more protected DisadvantagesNo variation - if the parent has a genetic disease, offspring does too. Requires two organisms, requires more energy EvolutionThere is very little chance of variation with asexual reproduction. Sexual reproduction leads to genetic variation in new generations of offspring. This is fundamental to evolution. found inSimple organismshigher invertebrates and all vertebrates
