Flower Structure LI : To recall the structure and function of the Flower

What did we learn last lesson?

Flowers

Flower structure

Stamen Structure Stamen Anther Filament Pollen grain Male sex cell

Female parts of a flower

Petals Bright colours for attracting insects

Sepals Protects the unopened flower

Nectary Makes sugary nectar…. ..to attract insects

Male parts of the flower Stamen – male part of the flower. Produces pollen grains Pollen – contains the male sex cells

Female parts of the flower Ovary – female part of the flower containing the ovules Ovule – contains the female sex cell Stigma – where the pollen grain attaches

Sex cells Humans Sperm egg Plants Pollen grains egg cell

Flower structure

Flower dissection Stick parts of flower onto paper and label different parts: Petal Stigma Stamen Ovary Ovule Pollen Egg cell Nectary

What have learned today? Success Criteria: I can describe the functions of the parts of flowers, ie sepal, petal, stamen, stigma, ovary, nectary. I can successfully carry out a flower dissection to identify these parts .

Ovule petal nectary Ovary stigma Pollen sepal
