• Sexual Reproduction

All of the offspring of an organism have the same genetic material, which is identical to the parent organism. From this, we can conclude that this organism -

• makes its own food
• is unicellular
• live in a marine habitat
• reproduces asexually

What are some of the facts about asexual reproduction?

• Takes only one mate to reproduce and takes a longer time to reproduce
• Takes a shorter amount of time to reproduce and it takes two mates to reproduce
• Reproduces diverse offspring and takes a longer time to reproduce
• Takes only one mate to reproduce and takes a shorter time to reproduce

What type of asexual reproduction is taking place?
Fishermen work hard to catch and remove all the starfish that get into their favorite shell fishing beds and the “underwater farms” where they raise clams and oysters. In the past, they put the starfish into their boats, cut them up with knives, and then throw the pieces of starfish overboard. They thought this would kill the starfish. What they did not know was that each piece of starfish will grow into a whole new animal.

This is when a new organism grows by cell division on the body of its parent. The bud, or offspring is identical to the parent. The bud, when large enough, can break off of the parent and live on its own.  Examples of this include yeast, hydra and potatoes.

If an environment suddenly changes, which type of reproduction would be most beneficial? Why?

• Asexual, because asexual organisms always have variation within species.
• Sexual, because sexual organisms have variation within species.
• Both Asexual and Sexual reproduction would be beneficial, because they both have variation within species.
• Asexual, because asexual organisms have no variation, so they can adapt to a changing environment.
