Answer:
Components of blood- Blood plasma and Formed elements which areblood cells and blood fragments.
Plasma helps in transportation, erythrocytes transport oxygen, leukocytes provides defese against diseases and platelets functions in blood clotting.
Explanation:
Blood has two components:
- Blood plasma, a liquid extracellular matrix.
- Formed elements which are blood cells and cell fragments.
Functions of Blood plasma:
- Water present in the plasma maintains the blood volume and transports molecules.
- Plasma proteins maintain osmotic pressure and pH.
- Globulins fight against infection.
- Fibrinogen aids in clotting.
- plasma also transport, nutrients, hormones and vitamins etc.
Functions of blood cells:
Red blood cells or erythrocytes contain hemoglobin that binds oxygen and transports the oxygen to different parts of the body.
White blood cells or leukocytes provide defence againts diseases by engulfing the cells or releasing antibodies.
Platelets are fragments of megakaryocytes. Platelets help to stop blood loss from damaged blood vessels by forming platelets plug.

Answer:
Undifferentiated inner cell mass
Explanation:
Human embryo has two types of cells in its initial stage, trophoblast and inner cell mass. Trophoblast forms the placenta and inner cell mass form the entire human body. Inner cell mass are pluripotent in nature i.e. they can give rise to any body part under right conditions.
Embryonic stem cells are derived from the inner cell mass. They are derived from pre implantation embryo since after implantation the inner cell mass begins to differentiate. Embryonic stem cells can replicate indefinitely without differentiating. They can give rise to all the three germ layers: ectoderm, mesoderm and endoderm. They can treat a number of disorders like genetic disorders, Parkinson's, spinal cord injury, cancers etc.
