WebEach cell within the blastula is called a blastomere. Figure 2. (a) During cleavage, the zygote rapidly divides into multiple cells without increasing in size. Figure 2. (b) The cells rearrange themselves to form a hollow ball with a fluid-filled or yolk-filled cavity called the blastula. (credit a: modification of work by Gray’s Anatomy ... WebThe blastula (7) begins to take on the appearance of a ball. 6. Blastula: This ball-like stage is called the blastula (5). Compare the size of the blastula to the original zygote. Note the blastocoel (6). 7. Early gastrula: During the late blastula stage a few cells on one side of the developing embryo begin to push into the blastocoel (8). ...
