Activity 1 Biology 2 Flowers

The document is a worksheet for a third quarter biology activity on flower dissection. Students are instructed to dissect a flower and identify and describe its various parts, including the sepals, petals, stamen, and pistil. They are asked questions to label the male and female reproductive structures and match terms to definitions. The goal is for students to learn the function of each flower part and how they work together for pollination and reproduction.
