What are the Different Parts of a Flower
1. Sepals
2. Petals
3. Stamen
4. Carpel
When a flower has all the four floral parts, it is called a complete flower. A flower missing any one of them is called an incomplete flower. Functions
Providing protection to the young flower buds from an injury by forming a tightly closed area Giving structural support to a flower
Functions
Protecting the reproductive structures in flowers Attracting pollinators like insects (e.g., bees, wasps, and butterflies), birds and other small mammals to transfer pollen from male to female reproductive part of a flower
a) Anther – Yellowish sac-like structure present at the head of the stamen. b) Filament – Slender stalk-like structure present at the tail of the stamen. Functions
Anther helps in producing and storing pollen grains Filament holds the anther and attaches it to the flower
a) Stigma – Head of the pistil that catches pollen grains. b) Style – The stalk of the pistil. When pollen grains reach stigma, a tube-like structure grows through the style called pollen tube, which reaches the ovary. c) Ovary – The base of the pistil that holds the eggs or ovules. The ovary later becomes the seed when the male and female reproductive cells fuse together, thereby forming the embryo, a process called fertilization. Functions
Stigma helps in receiving pollen grains and also in their germination Style supports the stigma and connects it to the ovary Ovary helps in developing, distributing, and nourishing the embryo
Ans. The androecium is the male reproductive part of a flowering plant, which is composed of one or more stamens. The gynoecium is the female reproductive part of a flowering plant, which is composed of one or more carpels. Q.2. What is a unisexual flower? Ans. When a flower has either stamens or carpels, but not both of them, it is called a unisexual flower. Example: papaya and watermelon. Q.3. What is a bisexual flower? Ans. When a flower has both stamens and carpels, it is called a bisexual flower. Example: rose and mustard flower. Q.4. Which part of a flower contains the ovary? Ans. The ovary is the enlarged basal portion of the pistil where ovules are formed.
