- hen՚s egg
- reptilian egg
- The correct sequence of appearance of the given structures during the development of CNS in any vertebrate is
- neural groove, neural plate, neural tube
- neural plate, netural groove, neural tube
- neural plate, neural tube, neural groove
- neural groove, neural tube, neural plate
- In Amphioxus, the coelom is formed by
- splitting of the lateral mesoderm
- development of an additional mesodermal layer from the somatic mesoderm
- spreading of the dorsal mesodermal somites
- the fonnation of mesodennal pouches from the dorsolateral walls of the archenteron
- Somatopleure is a double layered tissue consisting of
- somatic mesoderm and endoderm
- somatic mesoderm and ectoderm
- splanchnic mesoderm and endoderm
- somatic mesoderm and splanchnic mesoderm
- The mesoderm in chick embryo gives rise to all of the following organs except the
- heart
- kidney
- brain
- skeleton
- During cleavage, the cell division is very rapid. The daughter cells do not undergo any growth and the cells thus become gradually smaller in volume. Hence
- there is no growth in the volume of the embryo
- the embryo grows in volume
- the embryo becomes smaller in volume
- the embryo remains static
