It’s spring, and what better time to study meiosis and dissect daffodils.
Daffodilusa (pdf) has nice description of how to dissect daffodils. However, I had students collect the flowers, and sketch the outsides and insides (longitudinal bisection) before I gave them the handout.
I wanted them to practice drawing diagrams and observing features first, before we got into the discussion of what the parts were and what they did, to make sure they’d not forgotten all they’d learned when we did our animal dissections last semester.
They laid out their grids, did some very nice drawings, and then labeled what they’d drawn, based on the handout, over the weekend.
