Cell Development Quiz

What is the process called when unspecialized cells develop into specialized cells?

• Specialization

• Differentiation

• Transformation

• Multiplication

Answer explanation

Differentiation is the process where unspecialized cells develop into specialized cells. It involves the transformation of cells to perform specific functions.

What is the definition of fertilization?

• The process by which a sperm cell combines with a plant cell to form a new organism.

• The process by which a sperm cell combines with a blood cell to form a new organism.

• The process by which a sperm cell combines with an egg cell to form a new organism.

• The process by which a sperm cell combines with a rock to form a new organism.

Answer explanation

Fertilization is the process where a sperm cell combines with an egg cell to form a new organism.

What is the difference between a zygote and an embryo?

• The zygote is the female reproductive cell, while the embryo is the male reproductive cell.

• The zygote is the fertilized egg, while the embryo is the stage of development that follows the zygote.

• The zygote is the stage of development that follows the embryo.

• The zygote and the embryo are the same thing.

Answer explanation

The zygote is the fertilized egg, while the embryo is the stage of development that follows the zygote.

What are embryonic stem cells?

• Cells derived from the placenta

• Cells derived from the inner cell mass of a blastocyst

• Cells derived from adult tissues

Answer explanation

Embryonic stem cells are derived from the inner cell mass of a blastocyst, not from the placenta, adult tissues, or the outer cell mass of a blastocyst.

What are morphogens?

• Signaling molecules that regulate the pattern of tissue development in organisms during embryonic development.

• Proteins that transport oxygen in the blood

• Hormones that control the growth of hair and nails

• Enzymes that break down food in the digestive system

Answer explanation

Morphogens are signaling molecules that regulate tissue development during embryonic development.

What is the role of retinoic acid in cell development?

• Retinoic acid is only important in adult cell development.

• Retinoic acid regulates gene expression and controls cell differentiation during embryonic development.

• Retinoic acid is not involved in cell development.

• Retinoic acid inhibits cell growth and development.

Answer explanation

Retinoic acid regulates gene expression and controls cell differentiation during embryonic development.

During which process does fertilization occur?

• Photosynthesis

• Sexual reproduction

• Mitosis

• Cellular respiration

Answer explanation

Fertilization occurs during sexual reproduction. It is the process of combining male and female gametes to form a zygote.

What happens during cell differentiation?

• Cells stop dividing and become dormant.

• Cells become specialized in structure and function.

• Cells lose their ability to perform specific functions.

• Cells become identical in structure and function.

Answer explanation

During cell differentiation, cells become specialized in structure and function, allowing them to perform specific tasks efficiently.

What is the main function of embryonic stem cells?

• Repairing damaged tissues

• Differentiation into any type of cell in the body

• Regulating the immune system

• Production of red blood cells

Answer explanation

Embryonic stem cells have the unique ability to differentiate into any type of cell in the body, making them invaluable for medical research and potential treatments.

Which of the following is NOT a subtopic of this quiz?

• This one

• No

• Nope

• Girl... seriously

Answer explanation

Deep breathing is NOT a subtopic of this quiz because it is not mentioned in the answer choices.
