3. (quote-book) On earth, a germinated seedling can be placed in any position and the radicle will invariably turn the embryo plant "downward" and the hypocotle "upward". This is because positive root tropism toward gravity and negative stem tropism away from gravity. In the absence of gravity, will the plumules and the stem of the embryo plant reacting positively to phototropism guide the ''entire'' plant including the root system for its directional orientation?

4. (quote-book)

5. A capability or tendency for a pathogen (chiefly a virus) to infect a type of cell, tissue, organ, or host organism.

(..) The primary determinant of virus tropism is the presence on the cell surface of a suitable receptor which the virus can utilize to gain entry to the cell.
