What is the accessory whorls of flower?

Accessory whorls are also called as vegetative whorls which include sepals and petals. Essential whorls are also called as reproductive whorls which include stamens and pistil. A flower can be complete or incomplete based on the number of whorls present in it.

Which part of the structure protects the leaf?

leaf epidermis
Leaf function The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.

What is small leaf like structure of a flower called?

What are accessory whorls of a flower?

Parts of a flower can be grouped into two categories namely, accessory whorls and essential whorls.

  • Accessory whorls are also called as vegetative whorls which include sepals and petals.
  • Essential whorls are also called as reproductive whorls which include stamens and pistil.

What forms the outermost whorl of flowers?

sepals
The outermost whorl of the flower has green, leafy structures known as sepals. The sepals, collectively called the calyx, help to protect the unopened bud. The second whorl is comprised of petals—usually, brightly colored—collectively called the corolla.

Are sepals always green?

It is found on the outermost part of the flower, and like a petal, a sepal is considered to be a modified leaf. However, sepals are more likely to be confused with leaves since they are typically, but not always, green.

What is the calyx of a flower called?

Calyx: The calyx is the outermost whorl of the flower. The members of the calyx are called as sepals, which are small green, leaf-like structures protecting the flower during its bud stage. The calyx may be gamosepalous (united sepals) or polysepalous (free sepals).

What is the third whorl of a flower?

An androecium is the third whorl of most flowers. It is made up of male reproductive units called stamens. A stamen has a long stalk called a filament. At the top of the filament is a cluster of microsporangia called the anther.
