FLASHCARD QUESTION

Front

Embryo Noun

[em-bree-oh]

Back

Embryo


An early developmental stage of a multicellular organism from which the adult organism is gradually produced.

Example: This diagram shows a bird embryo developing inside an egg. A single fertilized cell divides and differentiates to form all the specialized parts, like the eye and limbs.

FLASHCARD QUESTION

Front

Differentiation Noun

[dif-er-en-shee-ay-shun]

Back

Differentiation


The process by which cells become specialized for particular functions during the development of an organism.

Example: An unspecialized stem cell develops and changes to become various specialized cells, such as a nerve cell, muscle cell, or blood cell.

FLASHCARD QUESTION

Front

Totipotent Adjective

[toh-tip-uh-tent]

Back

Totipotent


Describes a cell that can develop into any type of cell, including those of extra-embryonic membranes and placenta.

Example: This diagram shows that the earliest cells, like the zygote and morula, are totipotent, meaning they can become any cell type in the organism.

FLASHCARD QUESTION

Front

Blastocyst Noun

[blas-toh-sist]

Back

Blastocyst


A hollow ball of cells with an inner cell mass, formed during an early stage of human embryonic development.

Example: This diagram shows a blastocyst, a hollow ball of cells. It highlights the internal cell mass and the outer trophoblast, which are the first two cell types to differentiate.

FLASHCARD QUESTION

Front

Pluripotent Adjective

[ploo-rip-uh-tent]

Back

Pluripotent


Describes cells that can develop into any of the body's cell types but not the tissues surrounding the embryo.

Example: This diagram shows that pluripotent stem cells are a group of cells in an early embryo that have the potential to develop into any type of cell in the body.

FLASHCARD QUESTION

Front

Stem Cell Noun

[stem sel]

Back

Stem Cell


An unspecialized cell from which various types of differentiated cells develop through the process of cell division.

Example: This diagram shows that unspecialized stem cells can develop (differentiate) into many different types of specialized cells, like brain, bone, pancreas, or heart cells.

FLASHCARD QUESTION

Front

Multipotent Adjective

[mul-tip-uh-tent]

Back

Multipotent


Describes adult stem cells whose potential to differentiate is limited to replacing cells in the tissues where they are found.

Example: A multipotent cell, like the central mesenchymal cell, is a stem cell that can develop into multiple, but limited, types of specialized body cells.
