Which term matches the definition: outermost circle of flower parts that encloses a bud before it opens and protects the flower while it is developing?

• A. Sepal
• B. Petal
• C. Stamen
• D. Endosperm

Answer: (A)

The outer protective ring of flower parts is the sepal, which forms the calyx. Sepals are typically leaf-like and enclose the bud before the flower opens, protecting the developing structures inside from damage and drying out. After the flower develops, sepals may stay attached or fall away depending on the species. Petals make up the inner ring and usually attract pollinators; stamen are the male reproductive organs inside the flower; endosperm is the nutrient tissue inside seeds.
