Flower Structure
Flowers are the reproductive organs of flowering plants. They are responsible for producing seeds, which allow the plant to reproduce. Flowers come in a wide variety of shapes and sizes, but they all share some basic structures.
Parts of a Flower, Flower structure and reproduction worksheet answers
- Petalsare the colorful leaves that attract pollinators. They may be different colors, shapes, and sizes, depending on the flower.
- Sepalsare the small, green leaves that surround the petals. They protect the flower bud before it opens.
- Stamensare the male reproductive organs of the flower. They produce pollen, which contains the male gametes.
- Pistilis the female reproductive organ of the flower. It contains the ovary, which contains the ovules, and the style, which leads to the stigma.
- Receptacleis the base of the flower. It supports all of the other flower parts.
Flower Reproduction
Flower reproduction begins with pollination. Pollination is the transfer of pollen from the stamen to the pistil. This can be done by insects, birds, or other animals. Once the pollen reaches the pistil, it germinates and produces a pollen tube.
The pollen tube grows down the style to the ovary, where it fertilizes the ovules.
After fertilization, the ovules develop into seeds. The seeds are then dispersed by wind, water, or animals. When a seed lands in a suitable location, it will germinate and grow into a new plant.
Methods of Seed Dispersal
- Wind dispersal: Seeds are light and have wings or other structures that allow them to be carried by the wind.
- Water dispersal: Seeds are waterproof and can float on water.
- Animal dispersal: Seeds have hooks or other structures that allow them to attach to animals.

FAQ
What are the main parts of a flower?
The main parts of a flower include the petals, sepals, stamens, pistil, and receptacle.
How does pollination occur?
Pollination occurs when pollen grains are transferred from the male anthers to the female stigma of a flower, enabling fertilization.
What is the role of insects in pollination?
Insects play a crucial role in pollination by transferring pollen grains between flowers, facilitating fertilization and seed production.
How are seeds dispersed?
Seeds are dispersed through various methods, including wind, water, animals, and explosive mechanisms, ensuring the survival and spread of plant species.
