Answer:
Option B, The controls on cell growth and divisions can be turned on and off
Explanation:
There are signal proteins that control and regulate the cell growth and division process. For instance, mitogens help in removing the negative controls which would otherwise have blocked the cell cycle progression. Then there are growth factors that synthesize proteins and hence stimulate cell growth. Also there are some survival factors that suppress the apoptosis. Based on these three factors the cell division and growth can be turned on or off.
Hence, option B is correct
a drupe has usually only one seed but berries are characterized as having flesh endocarp and might have more than one seed hope this helps (if this is what u meant) also a drupe is a accessory fruit while a berry is a multiple fruit.
The process is called Exocytosis.
A special hint for ease:
EXO → Out
ENDO → In
