| 1245434755 | Morphogenesis | The process of giving shape to an organism and its parts. | 0 | |
| 1245434756 | Totipotence | When a single somatic cell can give rise to all cell types and create an entire organism. Example is the carrot cell develops into a whole carrot plant. | 1 | |
| 1245434757 | Pluripotent | Can differentiate to one cell fate. | 2 | |
| 1245434758 | Cell determination | Precedes cell differentiation and involves expression of genes for specific tissue proteins. | 3 | |
| 1245434759 | Induction | The induction of nearby cells by embryonic cells via cell signaling, which cause transcriptional changes. | 4 | |
| 1245434760 | Pattern formation | The development of organization in plants and animals, usually during the juvenile stages. In plants this occurs continually. | 5 | |
| 1245434761 | Axis development | Axis body positions are established early in development. Maternal effect genes code for cytoplasmic determination of position, an example is drosphilia body axis formation by egg polarity genes. | 6 | |
| 1245434762 | Morphogen | A bicoid mRNA that translates a bicoid protein to determine the anterior end of an early embryo. | 7 | |
| 1245434763 | Gap genes | Produce proteins that direct formation of segments after the embryo's major body axes are formed. Part of Segmentation formation. | 8 | |
| 1245434764 | Apoptosis | Programmed cell death cell signaling, non-inflammatory, apoptotic bodies. | 9 | |
| 1245434765 | homeobox | A transcription factor protein of 180 base pairs encodes a homeo domain that when activated can bind DNA. Homeobox mutations can affect organ development. | 10 |
