Reproduction in animals and plants Lesson 7
Lesson 7- learning intention Plant reproductive organs
Reproduction in plants Flowering plants undergo sexual reproduction to produce seeds. The male and female sex organs of a plant are found in the same flower
Plant sex cells Plants have male and female sex cells Don’t produce eggs and sperm (like humans) Produce POLLEN GRAINS and OVULES
Plant sex cells Pollen grains hold the MALE sex cell Ovules are the FEMALE sex cell
Quick task In your jotters draw a table which compares the sex cells in an animal to the sex cells in the plant SEX CELL Male Female Animal Plant
Parts of the Flower The STAMEN is the MALE part of the flower and is made up of the ANTHER and FILAMENT The ANTHER produces POLLEN grains The FILLAMENT holds the anther in place
Parts of the Flower The STIGMA is the FEMALE part of the plant. It is STICKY and catches pollen grains The OVARY contains the OVULES (the female sex cell).
Petals Bright and colourful to attract insects Labelling the plant Petals Bright and colourful to attract insects
