Asexual vs. Sexual Reproduction: Virtual Lab

Period: ______
PART #1: ASEXUAL REPRODUCTION
•
In this part of the lab you will observe several organisms undergoing asexual reproduction. It is important that you watch and listen closely
to each video provided in order to answer questions that will follow. After each video the questions will be located on the following
slide. These are the same questions that I have provided you in the lab sheet handout.
FISSION ?'S
• After viewing the videos of Euglena and Stylonchia, answer the questions below.
1.) Both, Euglena and Stylonychia, displayed binary fission in the videos. Describe the process of fission in your own words.
2.) What do you notice happening to the organisms as they get close to splitting?
3.) After fission occurs, are the two Euglena genetically similar? What about the two Stylonchia?
BUDDING ?'S
• After viewing the video of the Hydra, answer the following questions.
1.) Describe the process of budding.
2.) Compare the size of the offspring Hydra to the size of the parent Hydra in the video. Is the offspring Hydra ready to separate from the parent?
VEGETATIVE PROPAGATION ?'S
• After watching the Round-Leaved Sundew video, answer the following questions.
1.) Although not easily seen in the video, this plant does have a small flowering bud. When this flower dies it will drop onto the soil and has the
potential to grow into a new plant. Will this plant be genetically different or the same as the parent?
SPOROGENESIS ?'S
• After watching the videos of Scouring Rush and Mucor Mucedo, answer the following questions.
1.) What happened when the man in the Scouring Rush video flicked the top of the plant? What could result from him doing this?
2.) Where do you suppose the spores are located in the second video that showed Mucor Mucedo? How do you think they get dispersed?
FRAGMENTATION ?'S
• After watching the videos of the Starfish and the Planaria, answer the questions below.
1.) Although some of you may feel bad for the starfish in the video, he is going to be perfectly fine. Explain!!
2.) Why does the planarian have two heads? How could you fix this problem for the planarian?
AGAMOGENESIS ?'S
• After watching the video of the Rotifer, answer the following questions.
1.) What do you notice inside the rotifer?
2.) Describe the process of parthenogenesis.
PART #2: SEXUAL REPRODUCTION
•
In this part of the lab you will observe organisms undergoing sexual reproduction. It is important that you watch and listen closely to each
video provided in order to answer questions that will follow. After each video the questions will be located on the following slide. These
are the same questions that I have provided you in the lab sheet handout.
HERMAPHRODITISM ?'S
• After watching the video of the Earthworm, answer the following questions.
1.) Earthworms are hermaphrodites, which means...
2.) In the video two earthworms are side by side. If you look close enough they are actually connected at two different points on their bodies. What
do you suppose is happening where the two worms are connected?
3.) Will the offspring of these earthworms be genetic clones, if not, explain.
BIPARENTAL ?'S
• After watching the videos of the Salmon and Kangaroo, answer the following questions.
1.) Did the salmon reproduce internally or externally? What did you see in the video that supports your answer?
2.) What sort of parental care is observed in the video of the kangaroo?
3.) Genetically speaking, where did the offspring of the kangaroo get it's DNA?
