- Question 1 (1 point) Let's look at growth in Chlamydomonas . Which of the following statements is correct.? A. Like humans Chlamydomonas doesn't need sulfur (S) to grow. B. In the lag phase of growth, the number of cells is constant over time. C. A possible reason the cells stop growing in stationary phase is because the growth media has no more nitrogen (e.g. NH_(4)^+Cl) D. Most bacteria grow much more slowly than Chlamydomonas. √ Saved
