Biology- Parts Of The Flower

Front 1

anther

Back 1

The Anthers contain pollen sacs. The sacs release pollen on to the outside of the anthers that brush against insects on entering the flowers. The pollen once deposited on the insect is transferred to the stigma of another flower or the same flower. The ovule is then able to be fertilised.

Front 2

filament

Back 2

This is the stalk of the Anther.

Front 3

petal

Back 3

Petals are used to attract insects into the flower, they may have guidelines on them and be scented.

Front 4

stigma

Back 4

Is covered in a sticky substance that the pollen grains will adhere to.

Front 5

style

Back 5

The style raises the stigma away from the Ovary to decrease the likelihood of pollen contamination. It varies in length.

Front 6

sepal

Back 6

Sepals protect the flower while the flower is developing from a bud.

Front 7

ovary

Back 7

This protects the ovule and once fertilisation has taken place it will become the fruit.

Front 8

ovule

Back 8

The Ovule is like the egg in animals and once fertilisation has taken place will become the seed.

Front 9

receptacle

Back 9

This is the flower's attachment to the stalk and in some cases becomes part of the fruit after fertilisation e.g. strawberry.

Front 10

stamen

Back 10

male parts of flower, both anther and filament together

Front 11

carpel

Back 11

The stigma, style, ovary, and ovule all together, female parts of flower

Front 12

calyx

Back 12

outermost whorl, consists of sepals

Front 13

corolla

Back 13

all the petals collectively
