Aim
To observe the TS of mammalian blastula through permanent slides.
Materials Required
- Permanent slide
- Compound microscope
Procedure
Observe the permanent slide under a microscope and note down the features of TS of the mammalian blastula.
Observations
Blastula appears as a sphere with a cavity known as blastocoel. An outer layer of blastomeres known as trophoblasts is observed. One end of the blastula shows a cellular mass adhered to the trophoblast. This is known as the inner cell mass.
