WebWHITEFISH MITOSIS INTERPHASE The following slides are of the embryos if whitefish (an early stage of embryonic development called the blastula stage). When cells are not dividing, they are in a part of the cell cycle known as Interphase. WebThe whitefish embryo is a good place to look at mitosis because these cells are rapidly dividing as the fish embryo is growing. The onion root is also a good place because this is the area where the plant is growing. Remember that when cells divide, each new cell needs an exact copy of the DNA in the parent cell.

WebFish Embryo Toxicity (FET) Test INTRODUCTION 1. This Test Guideline describes a Fish Embryo Toxicity (FET) test mainly developed for use with the zebrafish (Danio rerio) but the test method can also be adapted to fathead minnow (Pimephales promelas), Japanese medaka (Oryzias latipes) and other relevant species of interest (1).

WebCell Division - Mitosis - in Whitefish Blastula Cells. This cell is in the interphase stage of the cell cycle. Early in interphase the cell (A) reaches its full size and then starts preparing for its next division. Preparation includes chromosome replication, replication of cellular organelles, including centrioles, and the synthesis of ...

In fish eggs, cleavage occurs only in the blastodisc, a thin region of yolk-free cytoplasm at the animal cap of the egg.Most of the egg cell is full of yolk. The cell divisions do not completely divide the egg, so this type of cleavage is called meroblastic (Greek, meros, “part”).
