The Importance of Cell Differentiation Flashcards

All 5 cards in this deck

What is cell differentiation?: The process by which a cell becomes specialised to carry out a particular job.
Why is cell differentiation important in the development of an organism?: It produces specialised cells, so tissues and organs can carry out different functions efficiently.
State two uses of percentile charts.: To monitor height/growth over time; to compare the growth of an individual against the standard growth pattern.
On a height percentile chart, what does being on the 50th percentile mean?: 50% of children of that age are shorter and 50% are taller.
True or false? A single reading on a percentile chart that is below the 50th percentile shows a child has a growth problem.: False. A possible problem is shown when a child's growth crosses percentile lines over time, not by one low reading.
