Question
Cells in an embryo must commit to making particular types of tissues. For each of the following statements, insert the missing word(s) from the list:
1. If cells from one part of an embryo are transplanted to another part, and they develop into the tissue they would have made originally, the cells are said to be ____________ .
2. In general, cells from early stage embryos are able to make ____________ cell types compared with cells from later stage embryos.
3. The reason why different cells turn into different tissues is because of differences in ____________ .
4. With cytoplasmic determinants, a cell will become committed to a particular future because it has inherited a particular mRNA or protein from ________.
5. A cell in an embryo will produce intestinal cells later in development. When that cell is removed and grown separated from the embryo, it produces muscles instead. This means that in order to make intestinal cells, a/an ____________ is necessary.
6. A cell-cell interaction that changes the gene expression is called a/an ____________.

1. If cells from one part of an embryo are transplanted to another part, and they develop into the tissue they would have made originally, the cells are said to be determined.
2. In general, cells from early stage embryos are able to make more cell types compared with cells from later stage embryos.
3. The reason why different cells turn into different tissues is because of differences in gene expression
4. With cytoplasmic determinants, a cell will become committed to a particular future because it has inherited a particular mRNA or protein from its mother.
5. A cell in an embryo will produce intestinal cells later in development. When that cell is removed and grown separated from the embryo, it produces muscles instead. This means that in order to make intestinal cells, a cell-cell interaction is necessary.
6. A cell-cell interaction that changes the gene expression is called an induction.
