The outermost whorl of a flower is called the calyx
The outermost whorl circle of a flower is called the calyx. By looking at the calyx, you can typically see if the flower is a male or female.
Sepals

Whorl is a short stalk where the important parts of a flower are attached. The outermost part attached on the whorl is the calyx that is made of sepals.
Modified leaf that protects a flower bud
Dermal tissue is the outer covering of a flower. The inner part of a flower is commonly called the stamen. Another part of a flower is called the petal.
The outermost circle is seconds, the one directly inside is minutes, the next is hours, then day, then month. So when the outermost circle closes up, the second circle, minutes, gets a little bigger, and the seconds circle starts àll over again.
carpels or pistils form the innermost whorl of the flower
The Epidermis
Yes, it can as long as it is not the tangent line of the outermost circle. If it is tangent to any of the inner circles it will always cross the outer circles at two points--so it is their secant line--whereas the tangent of the outermost circle is secant to no circle because there are no more circles beyond that last one.
a sepal is the outermost part of a flower and is predominately green and can be free or fused. Sepals are the green leaves that are basal to the flower petals. collectively the sepals make up the calyx.
