How do plants reproduce?
What is asexual reproduction?
It involves a single parent only, no gametes. no fertilisation takes place and the offspring are clones of each other and the parent plant
How can asexual reproduction happen artificially?
It happens by vegetative propagation
The techniques include cuttings, grafting and micro propagation

What is the difference between sexual and asexual reproduction?
Sexual reproduction is when the male sex cell and a female sex cell join together
Asexual reproduction does not involve fertilisation and there is only one parent
What is the male part of the flower called?
It is called the stamen
It is made up of the anther and filament
What is the female part of the flower called?
It is called the carpel
It is made up of the stigma, style and ovary
Sate the function of the sepal
To protect the flower before it blooms
State the function of the anther
To produce pollen which is the male gamete
State the function of the filament
To help the anther get the pollen
State the function of the carpel
To make the ovary
State the function of the ovary
To produce the egg which is the female gamete
State the function of the stamen
To make the pollen
State the function of the petal
To attract insects to the flower for pollination
List the five stages involved in sexual reproduction of plants
Seed and Fruit Formation
Seed and Fruit Dispersal
What is pollination?
This is the transfer of pollen from the stamen to the carpel
State two ways in which pollen is carried from one flower to another flower
What is fertilisation?
This is the joining of the pollen and the egg to form a zygote
State the two parts of the embryo
1. The plumula will become the plant shoot
2. The radicle will become the plant root
How are seeds dispersed?
Wind eg. dandelions
Animal eg. strawberry
Water eg. water lily
Self dispersal eg. peas
What is germination?
This is the growth of a seed to form a new plant
What factors (things) are needed for germination to occur?
