Question
In sea urchins, the process of fertilization produces a(n) _____.
Solution
In sea urchins, the process of fertilization produces a zygote.
Here are the steps of the process:
-
The male sea urchin releases sperm into the water, and the female releases eggs. This is known as external fertilization.
-
A sperm cell and an egg cell combine in the water. This process is called fertilization.
-
The fertilized egg, now called a zygote, begins to divide and grow into a new sea urchin.
-
The zygote undergoes several rounds of cell division, forming a blastula, which is a hollow ball of cells.
-
The blastula then undergoes gastrulation, forming a gastrula with different layers of cells that will develop into different parts of the sea urchin's body.
-
The gastrula continues to develop into a larva, which will eventually grow into an adult sea urchin.
