Carpel – this is the female part of the flower, with three main parts:
Sepals – these form a case that protects the flower before it opens when it is still a bud.

The kōwhai has male and female parts in the same flower. Some other plants have separate male and female flowers, either on the same plant or on different plants.
Petals – in kōwhai, these are large and brightly coloured to attract birds.

Kawakawa is just one example of a New Zealand native plant with male and female flowers on separate plants. It is wind pollinated, so doesn’t have petals as it doesn’t need to attract animals.
The kōwhai is a well known New Zealand flower and has flower parts that are easy to recognise. Masses of bright yellow kōwhai flowers are a common springtime sight in gardens and in the wild. The flowers are pollinated by birds, especially tūī and bellbirds, so are brightly coloured to attract them. The flowers are shaped like a tube, so birds pick up or leave pollen when they stick their beaks in to reach the nectar at the bottom.
It takes a bit of practice to be able to recognise and name parts of flowers, because each plant species has different flowers. Try naming the parts in this cutaway picture of a tulip flower.
Stamen – this is the male part of the flower, article flower structure with two main parts:
Follow up the science ideas and concepts covered in this article with one, or more, of these activities below with your students.
Most flowers have the same basic parts, even though they come in all sorts of shapes, sizes and colours. Flowers are there to make sure that pollination and fertilisation take place, so that seeds can be produced. If you want to understand about these stages in the life cycle of flowering plants, it helps to know about flower structure and the names for different parts.

Nectary – this makes and holds nectar, a sugary liquid food for birds .
Of course, not all flowers are the same as kōwhai. Like most bird-pollinated flowers, it has big colourful petals, but many insect-pollinated flowers only have small white or greenish petals – they tempt insects to visit using smell rather than colour. Many wind-pollinated flowers, such as grasses and a number of our flowering trees, don’t have petals at all. Nectar is no use to wind-pollinated flowers either, as they don’t need to attract animals. flower articles
