which parts of a typical flower are important and why?
Answers
Explanation:
A flower can be defined as the reproductive unit of any flowering plant (angiosperms). Flowers carry out sexual reproduction in angiosperms. A typical flower is a modified stem with a condensed axis. A flower has four different parts i.e., the calyx, corolla, androecium, and gynoecium. Androecium and gynoecium represent the male and female reproductive organs of a flower (respectively). Bisexual flowers are those which contain both androecium and gynoecium, while unisexual flowers contain either gynoecium or androecium. The corolla and the calyx are generally distinct, but may sometimes be fused (called perianth). A flower that contains all four floral parts is called a complete flower.
Parts of flowers
(A) The calyx forms the outermost whorl of a flower, which contains sepals. They are green, leaf–like structures that cover and protect the flowers during the bud stage. When the sepals of a flower are free, they are called polysepalous, while fused sepals of a flower are called gamosepalous.
(B) The corolla of a flower is a layer that lies inside the calyx. It contains beautifully coloured petals, which help in attracting insects for pollination. When the petals are free, they are called polypetalous, while fused petals are called gamopetalous.
(C) The androecium or the stamen is the male reproductive part of a flower. It consists of two parts, the filament and the bilobed anther. The bilobed anther is the site for meiosis and the generation of pollen grains.
(D) Gynoecium represents the female reproductive part of a flower. It consists of an ovary. The ovary is connected by a long tube (called style) to the stigma. The ovary bears numerous ovules attached to the placenta.

Answer:
hiii mate....
Explanation:
A typical flower has the four main parts that are calyx , Corolla , androecium and gynoecium . The outermost whole of the flower has green leafy structures that is known as the sepals . The sepals collectively known as calyx, which helps to protect the an opened bud.
The stigma contains sticky substance whose job is to catch the pollen grains from different pollinators or those dispersed through the wind. they are responsible to begin the process of fertilization. Ovary : They form the base of the pistil. Therefore the ovary holds the ovule. In this way the parts of the typical flower are important.
hope it help you if it help you please mark my answer as a brain list be safe and stay at your home .....
Thankuu.........
