Answer #1

Pre eclampsia is characterised by high blood pressure and high protein levels.
Poorly developed placenta results in impaired vascularisation. This results in impaired perfusion which causes oxidative stress, hypoxia. This results in pre eclampsia.
After 20 weeks of pregnancy increasing nutritional demand by the fetus results in poorly developed placenta to cause  vascular endothelial malfunction and vasospasm. This causes high blood pressure.

As the pre eclampsia occurs due to abnormal development of placenta its removal is the only cure for pre eclampsia. So delivering the baby and placenta is the necessary to avoid complications.
