Characterize A C. elegans:
| A C. elegans Embryo Development |
| About this movie:
A wild type C. elegans embryogenesis (from an embryo
to a worm). |
| Observation: Please observe this movie and come up with your observations and questions for discussion. |
| Background Knowledge: Here is some background information to help you observe this movie. |
|
| Questions to Get You Thinking: Are the two daughter cells same or different sizes? Does the embryo grow while its cell number increases? Here are more questions to get you started. |
| Dimensions of this embryo:
55 (µm in width) X 30 (µm in height), Magnification:
1000X |
| Note: It takes approximately
14 hours for a C. elegans zygote to hatch. As you might
notice in this movie, the recording time for the embryo development
only up to around 10 hours. A few hours were skipped to make it
easier for presentation. |
