Characteristic feature of apoptosis -
-
Cell membrane intact
-
Cytoplasmic eosinophilia
-
Nuclear moulding
-
Cell swelling
Explanation:
- No option is exactly correct in this question, as chromatin condensation is the most characteristic feature of apoptosis.
- But, we have to choose one option anyways.
- Amongst the given options two features are seen in apoptosis : -
Option a → Cell membrane intact
Option b → Cytoplasmic eosinophilia
-
Cytoplasmic eosinophilia is not characteristic feature of apoptosis; cytoplasmic eosinophilia is also seen in necrosis.
-
On the other hand Intact cell membrane is a striking feature of apoptosis and it differentiates apoptosis from necrosis (in which cell membrane is damaged)
-
Mast characteristic feature of apoptosis → Chromatin condensation (Fyknosis)
-
Earliest change of apoptosis → Cell shrinkage
-
End stage of apoptosis → Formation of cytoplasmic blebs & apoptotic bodies.
-
Most striking feature of apoptosis → Absence of inflammation.
