1

LABEL the parts of the FLOWER

2

Filament
 

Supports & holds anther. Part of stamen.
 

3

Anther
 

  • Part of stamen
  • Contains pollen.
     

4

Ovary
 

Eggs stored here, join with pollen.
 

5

Stigma
 

Sticky to catch pollen.
 

6

Petal
 

Brightly coloured - To attract insects and birds
 

7

Stamen
 

Male part of flower. Makes pollen. Made up of anther & filament.
 

8

Carpel
 

Female part, seeds made here. Consists of stigma, style, ovary.
 

9

Stem
 

Green stalk. Provides support.
 

10

Sepal
 

Special leaves form ring around bottom. Protects the buds.
 

11

Style
 

Supports stigma
 

12

Receptacle
 

Top part of stalks where flowers attached.
 

13

Desribe the first stage of PLANT fertilisation

Pollen is transferred from one plant to another (By wind, insect or bird etc) and lands on the STIGMA

14

Describe the second stage of plant fertilisation

When the pollen grain lands on the STIGMA a pollen TUBEgrows down through the STYLE towards the OVARY

15

Describe the third stage of PLANT fertilisation

The NUCLEUS of the pollen grain then passes down the tube to fertilise the egg cell inside the ovule.

16

Describe the last stage of PLANT fertilisation

The fertilised egg cell develops into an embryo, the ovule becomes the seed and the ovary forms the fruit
