asexual reproduction in plants

Asexual reproduction in plants:

• bulbs & tubers
• runners
• cuttings & grafting
• cloning (see book)

Steps of sexual reproduction in plants:

• pollination - transfer of pollen to stigma (self or cross)
• fertilisation - fusion of egg cell and pollen

• dispersal - water, insects, wind. 
• germination - seed starts to develop
