|---|---|---|---|---|---|
| Apical Meristem | Embryonic plant tissue in the tips of roots and in the buds of shoots that supplies cells for the plant to grow in length.
🗑
|
||||
| Apoptosis | The changes that occur within a cell as it undergoes programmed cell death, which is brought about by signals that trigger the activation of a cascade of suicide proteins in the cell destined to die.
🗑
|
||||
| Cell Differentiation | The structural and functional divergence of cells as they become specialized during a multicellular organism’s development; dependent on the control of gene expression.
🗑
|
||||
| Cell Lineage | The ancestry of a cell.
🗑
|
||||
| Chimera | An organism with a mixture of genetically different cells.
🗑
|
||||
| Clone | (1) A lineage of genetically identical individuals or cells. (2) In popular usage, a single individual organism that is genetically identical to another individual. (3) As a verb, to make one or more genetic replicas of an individual or cell.
🗑
|
||||
| Cloning | Using a somatic cell from a multicellular organism to make one or more genetically identical individuals.
🗑
|
||||
| Cytoplasmic Determinants | The maternal substances in the egg that influence the course of early development by regulating the expression of genes that affect the developmental fate of cells.
🗑
|
||||
| Determination | The progressive restriction of developmental potential, causing the possible fate of each cell to become more limited as the embryo develops.
🗑
|
||||
| Egg-Polarity Gene | Another name for a maternal effect gene, a gene that helps control the orientation (polarity) of the egg.
🗑
|
||||
| Embryonic Lethal | A mutation with a phenotype leading to death at the embryo or larval stage.
🗑
|
||||
| Homeobox | A 180-nucleotide sequence within homeotic genes and some other developmental genes that is widely conserved in animals. Related sequences occur in plants and prokaryotes.
🗑
|
||||
| Homeotic Gene | Any of the genes that control the overall body plan of animals and plants by controlling the developmental fate of groups of cells.
🗑
|
||||
| Induction | The ability of one group of embryonic cells to influence the development of another.
🗑
|
||||
| Maternal Effect Gene | A gene that, when mutant in the mother, results in a mutant phenotype in the offspring, regardless of the genotype.
🗑
|
||||
| Model Organism | An organism chosen to study broad biological principles.
🗑
|
||||
| Morphogen | A substance, such as Bicoid protein, that provides positional information in the form of a concentration gradient along an embryonic axis.
🗑
|
||||
| Morphogenesis | The development of body shape and organization.
🗑
|
||||
| Organ Identity Genes | Plant homeotic genes that use positional information to determine which emerging leaves develop into which types of floral organs.
🗑
|
||||
| Pattern Formation | The ordering of cells into specific three-dimensional structures, an essential part of shaping an organism and its individual parts during development.
🗑
|
||||
| Pluripotent | Describing a stem cell, from an embryo or adult organism, that can give rise to multiple but not all differentiated cell types.
🗑
|
||||
| Positional Information | Signals to which genes regulating development respond, indicating a cell’s location relative to other cells in an embryonic structure.
🗑
|
||||
| Segmentation Gene | A gene of the embryo that directs the actual formation of segments after the embryo’s axes are defined.
🗑
|
||||
| Stem Cell | Any relatively unspecialized cell that can divide during a single division into one identical daughter cell and one more specialized daughter cell, which can undergo further differentiation.
🗑
|
||||
| Totipotent | Describing a cell that can give rise to all parts of an organism.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
