How does the single cell - the fertilize
d egg - give rise to a complex, multicellular organism?Consists of more than one cell - evolved into 6 groups - to reproduce must solve the problem of generating an entire organism from germ cells.
How does cellular differentiation occur in eukaryotic cells?
Through gene expression- specific combination of genes that are turned on or off and determines how a cell functions.
What role do stem cells play in cell differentiation?
Stem cells can differentiate into specialized cells and can then further produce more cells.
How do chemical signals control cellular activity?
Individual cells receive signals at the same time, they determine the information that they have received and then put it into an action plan. They also send out messages and signals for cells near and far to receive.
