What is it ? How it works? How it works? How it works? How it works How it works? The late Daniel Mazia was a biological research scientist who first studied cell embryology using Sea Urchins. Scientists at Marine Hopkins Station of Stanford University work on similar cell biology experiments. In this experiment, the eggs of sea urchins are externally fertilized with sea urchin sperms and the various developmental stages of the fertilization process are observed with a microscope.

In the experiment, you will learn about the different stages of fertilization such as mitosis, nuclear migration, zygota, and gastrulation. You will receive questions at the end of every topic to reinforce your understanding.

In Animals: The embryo of vertebrates is defined as the organism between the first division of the zygote (a fertilized ovum) until it becomes a fetus. An embryo is called a fetus at a more advanced stage of development and up until birth or hatching. Stages: morula-> blastula->gastrula.

Gametes can be obtained easily, sterility is not required, and the eggs and early embryos of many commonly used species are beautifully transparent.

Pay attention to how Dr. Jason Hodin first forms a hypothesis, collects data, analyzes data and draws a conclusion. At the end of each section, you will get a chance to test your understanding of the material.

Founded in 1892, Hopkins was the first marine laboratory to be established on the American Pacific coast. Since that time, many notable scientists, as well as undergraduate and graduate students have come to the Station to study and work towards a better understanding of the ocean and its species.
