Biological Physics of the Developing Embryo
In centrolecithal meroblastic cleavage (characteristic of the embryo of the fruit-fly
Drosophila. see Chapter 1 0), unlike the other types pictured, the nuclei divide in
a common cytoplasm at the center of the egg during early development.

(6) Centrolecithal eggs. The yolk is localized at the center and the cytoplasm
forms a thin layer on the surface, e.g. Insects. (c) Isolecithal eggs. The small
amount of yolk is uniformly distributed in the entire ovums, e.g. Amphioxus.

PROBLEM 23-2 Differentiate between isolecithal, telolecithal, and centrolecithal
eggs . Which organisms are characteristic of each? Solution : The eggs of
different animals vary greatly in the amount and distribution of the yolk they
contain.

The centrolecithal egg has superficial cleavage. Here any cavity comparable to
blastocoel does not form. However, the formation of the epithelium on the surface
of the egg, after the nuclei have migrated to the exterior can be compared to the ...

(c) Centrolecithal egg. In insects and other arthropods eggs are centrolecithal.
Their size is relatively small containing a good amount of yolk concentrated
centrally surrounded by a peripheral layer of cytoplasm. No chordate has
centrolecithal ...

Progress in Invertebrate Zoology
The centrolecithal egg of Idotia has one membrane, the chorion, and a vitelline
membrane becomes evident at the 8-cell stage. The nuclei reach the periplasm
simultaneously and spread evenly in the 16-cell stage. The cell boundaries
appear ...
