Who is considered the father of animal cell culture?

• Louis Pasteur

• Ross Harrison

• Robert Koch

• Watson and Crick

The first successful animal cell culture was developed using:

• Chicken liver cells

• Frog nerve cells

• Human skin cells

• Mouse embryo cells

Pluripotent cells are capable of:

• Differentiating into one specific cell type

• Becoming any cell type in the body

• Dividing once

• Producing antibodies only

Which of the following is a commonly used balanced salt solution?

• NaCl

• Ringer's solution

• DMEM

• PBS

The primary purpose of a balanced salt solution is to:

• Provide vitamins

• Maintain osmotic balance and pH

• Inhibit bacterial growth

• Act as a carbon source

Which gas is important for maintaining pH in cell culture media?

• Oxygen

• Nitrogen

• Carbon dioxide

• Hydrogen

CO₂ is used in cell culture to:

• Inhibit contamination

• Provide oxygen

• Maintain pH through bicarbonate buffer

• Act as a disinfectant

Which of the following is commonly used as a pH indicator in culture media?

• Phenol red

• Methylene blue

• Safranin

• Crystal violet

The function of serum in culture media includes:

• Providing water only

• Buffering pH

• Supplying growth factors, hormones, and adhesion molecules

• Acting as a detergent

A common animal serum used in cell culture is:

• Bovine growth serum

• Human plasma

• Fetal bovine serum (FBS)

• Chicken serum
