Which event does not take place during interphase?

a. cellular growth

b. crossing over

c. duplication of chromosomes

d. production of organelles

The correct answer is "crossing over."

Cellular growth takes place under interphase, specifically under G1 phase of interphase wherein there is increase in cell proteins and structure. Duplication of chromosomes (or DNA synthesis) takes place under interphase, specifically under the S phase of interphase. In the S phase, there is also duplication of organelles. Crossing over takes place under prophase I of meiosis.
