Question

During the first two months, the developing human is referred to as an embryo. The embryo has three layers from which all body organs develop. At the same time, placenta stores glycogen and fat in first two months of pregnancy. Why?

• A. Glycogen and fats are energy reserves and there is no liver formation in embryo stage, due to this reason glycogen and fats are present in placenta.
• B. Glycogen and fats are used as energy source by a baby at the time of development.
• C. Glycogen and fat layers secure fetus by forming cell wall.
• D. Glycogen and fat layers secure fetus from external agitation and act as thermo regulator.

Answer 1

The correct option is A

Glycogen and fats are energy reserves and there is no liver formation in embryo stage, due to this reason glycogen and fats are present in placenta.

During the first two months, the developing human is referred to as an embryo. The embryo has three layers from which all body organs develop. During the second trimester the developing human is referred to as a fetus. Until liver formation happens, glycogen and fat reserves are used as energy source from placenta.
