1

SA To V Ratio

The surface area to volume ratio is the amount of surface area per until volume of an object or collection of object.

2

Interphase

The resting phase between successful divisions of the cells, or between the first and second divisions of meiosis.

3

Mitosis

A type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus.

4

Cytokinesis

The cytoplasmic division of a cell at the end of mitosis, bring about the separation into two daughter cells.

5

Gene

A portion of a DNA Molecule.

6

Chromosome

A structure of nucleic acids and proteins found in the nucleus of most living cells.

7

Differentiated Cell

The process by which a less specialised cell becomes a more specialised cell type.

8

Undifferentiated Cell

Stem cells are undifferentiated biological cells that can differentiate into specialised cells.

9

Embryonic Stem Cells

Embryonic stem cells are derived from the inner cell mass of a blastocyst.

10

Adult stem cell

Adult stem cells are undifferentiated cells, found throughout the body after development.

11

Zygote

A diploid cell resulting from the fusion of two haploid gametes.

12

Cloning

An organism or cell.

13

Therapeutic Cloning

The production of embryonic stem cells for use in replacing or repairing damaged tissues or organs.
