Suman has given a flower she was asked to pick the different whorls of flower by forcep. She pulled each part of the flower and laid them on the chart paper in a sequence and named them W, X, Y, Z (from outer to inner whorl). She was unable to name them. She called her class mates to help her in indentifying the different parts of flower. Her friend Alka also helped her knowing that which part of flower produce male gametes and female gametes.

Answers
Answer:
- Out of the four whorls, 'W' depicts the outer most whorl sepal.
- Honey bees are attracted to the whorl petal.
Explanation:
Every flower has four floral whorls. They are, from outer to inner, Calyx, corolla, androecium, and gynoecium. The members of the calyx are called sepals, corolla's are called petals. The androecium is made up of stamens and the gynoecium is composed of carpels. So here, Suman has sequenced the whorls as, W- calyx-sepals, X- corolla- petals, Y- androecium- stamens, and Z- Gynoecium- carpels. The parts of flower identified by Alka which are producing male and female gametes are androecium and gynoecium, respectively.
The calyx is the outermost part of a flower, which protects the flower in the buds stage.
The corolla is the part that is next to the calyx that is attracted by the honeybees. Because the petals are usually brightly colored to get attracted by the pollinators.
