Flower structure diagram

Information sheet

Use these diagrams to identify the structure and name different parts of a typical flower

  • School term: All year round
  • Level of experience: No experience needed
  • Subject(s): Science, Art&DT


You can use the image below as a worksheet for your students to label the different parts.


Parts of the flower 

  • Petal: brightly coloured to attract pollinators 
  • Stigma: sits at the top of the carpel and is where pollen is captured. It is often sticky so that the pollen can be caught. 
  • Style: the tube that pollen travels down to the ovary, joining the ovary to the stigma. 
  • Ovary: produces and contains unfertilised seeds 
  • Anther: pollen is produced here which is usually yellow and can be seen on the underside of pollinators after they have visited the flower.  
  • Filament: the tube that holds up the anther so that it is accessible for pollinators to reach or for the wind to blow the pollen. 
  • Sepal: leaf like protective cover that protects the flower when it starts to bud 
  • Receptacle: the base of the flower that supports the weight of the whole flower structure and attached it to the plant stem. 
  • Stamen: the male reproductive part of the flower that is made up of the Anther and filament. 
  • Carpel: the female reproductive part of the flower that is made up of the stigma, style and ovary.

Next steps:

  • Why not look at the different parts of a whole plant to help with understanding structure and function. 
  • Look for differences in a variety of plants. This could be in observing leaf shape, colour, texture, shape and size of flowers and types of roots.
  • Think about where the plant likes to grow - is this reflected in the structure?
  • Observe whether flowers are visited by flying insects to pollinate them and use our spotter guide to identify pollinators.
