Fish blastodisc
WebThe blastodisc, also called the germinal disc, is the embryo-forming part on the yolk of the egg of an animal that undergoes discoidal meroblastic cleavage. Discoidal cleavage occurs in those animals with a large proportion of yolk in their eggs, and include insects , fish , reptiles and birds . [2] WebMitosis is part of the cell cycle (See Figure 13.1) The cell cycle refers to the series of events that describe the metabolic processes of growth and replication of cells. The bulk of the cell cycle is spent in the “living phase”, known as interphase. Interphase is further broken down in to 3 distinct phases: G1 (Gap 1), S (Synthesis) and ...

WebLike fish eggs, the yolky eggs of birds undergo discoidal meroblastic cleavage. Cleavage occurs only in the blastodisc, a small disc of cytoplasm 2–3 mm in diameter at the animal pole of the egg cell. The first cleavage furrow appears centrally in the blastodisc, and other cleavages follow to create a single-layered blastoderm (Figure 11.8).

WebBlastodisc formation takes advantage of the pre-existing biased distribution of cytoplasmic and yolk components of the oocyte. After egg activation, this bias is enhanced by the animal pole-oriented streaming of ooplasm, a process that results in the separation of ooplasm from the yolk and lifting of the animal cortex to form a one-cell embryo. WebWhy are whitefish blastula used to study mitosis? The blastula is an early stage of embryo development and represents a period in the organism's life when most of the cells are …

WebMar 17, 2024 · Since only the blastodisc becomes the embryo, this type of meroblastic cleavage is called discoidal (Gilberd, 2003). The silver barb is a short-cycle species that, like Tilapia, can be farmed with low technology and relatively less effort than other species, being thus popular as a farmed fish in Bangladesh, where it is known as Thai Sharpunti
WebFeb 21, 2024 · 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.
