Parts of the Flower



1. Stamen- this is the male part of the flower. It is made up of the filament and anther, it is the pollen producing part of the plant. The number of stamen is usually the same as the number of petals. http://homeworks-edsci.blogspot.com

2. Anther- this is the part of the stamen that produces and contains pollen. It is usually on top of a long stalk that looks like a fine hair.

3. Filament- this is the fine hair-like stalk that the anther sits on top of.

4. Pistil- this is the female part of the flower. It is made up of the stigma, style, and ovary. Each pistil is constructed of one to many rolled leaflike structures.

5. Stigma- one of the female parts of the flower. It is the sticky bulb that you see in the center of the flowers, it is the part of the pistil of a flower which receives the pollen grains and on which they germinate.

6. Style- another female part of the flower. This is the long stalk that the stigma sits on top of.

7. Ovary- the part of the plant, usually at the bottom of the flower, which has the seeds inside and turns into the fruit that we eat. The ovary contains ovules.

8. Ovule- the part of the ovary that becomes the seeds. http://homeworks-edsci.blogspot.com

9. Petal- the colourful, often bright part of the flower. They attract pollinators and are usually the reason why we buy and enjoy flowers.

10. Sepal- the parts that look like little green leaves that cover the outside of a flower bud to protect the flower before it opens. http://homeworks-edsci.blogspot.com

11. Pollen tube- reaches the ovule by growing down through the style, carrying the male gametes inside.


Four Main Parts of Typical Flower (in sexually reproduces plants, the flower is the reproductive organ) http://homeworks-edsci.blogspot.com

1. Calyx- forms the outer part and consists of leaflike sepals.

2. Corolla –
consists of the petals.

3. Stamens and Pistils- make up a flower’s reproductive parts.

Flower Types

1. Imperfect Flower- a flower that has either all male parts or all female parts, but not both in the same flower. Examples: cucumbers, pumpkin, and melons.

2. Perfect Flower- a flower that has both the male parts and female parts in the same flower. Examples: roses, lilies, and dandelion.


Two Main Steps in Flower Reproduction



Pollination- is the transfer of pollen from a stamen to pistil.







Fertilization- is the union of a sperm with an egg cell.

Reproduction in Plants

Plant Reproduction

- is the process by which living things produce their own kind.



Sperm Cell


- male cells of a flower, they are in pollen produced by the stamen.



Egg Cell

- female cells of a flower, they are in ovules produced by the pistil.


Two Kinds of Reproduction




Asexual Reproduction
- only one parent is needed to reproduce a living thing.




Sexual Reproduction
– two parents are needed to produce a new living thing by contributing one sex cell each.






Four Basic Method of Asexual Reproduction among Plants



Fission- the cell splits into two similar new cells.
Ex: algae and fungi










Budding- the bud splits off and then develops into a new cell.











Sporulation- produce spores, each spore grows into a complete new plant.









Vegetation Propagation- a part of a plant grows into a new plant that is complete because of the process called regeneration.
