Aloha Ms. Welch! This quarter we are learning about how organisms reproduce and create offspring with the same traits. We think immediately about the phytoplankton in the water and how it 'blooms.' How do the diatoms and other phytoplankton reproduce, asexually or sexually? My students are about equally split, 50/50. Also, how long does it take for a phytoplankton to reproduce? Lastly, how long do they live and how do you tell old phytoplankton from younger phytoplankton? Mahalo plenty! Mrs. Prevenas and students
