Together called the CARPEL
Together called the STAMEN
Some of the pollen sticks on the STIGMA
Pollen is produced in the ANTHER
The pollen goes down a small tube to the EGG
There are lots of eggs in most plant ovaries.
The anther explodes and pollen just goes everywhere
Sexual reproduction is where two different cells meet
Sex cells are called GAMETES
The female gamete is theEGG
When the pollen and egg meet this is called FERTILISATION
Pollen is the male gamete
Small and green
No Scent or Nectar
Carry a large amount of very small pollen.
Contain sweet liquid called
Anthers contain a small amount of large pollen
When the male gamete POLLEN
Gets inside the female gamete or EGG
They form aZYGOTE
This is the first cell of a new plant
(OIL and STARCH)
The two together make the EMBRYO
Zygote forms here
Wet and warm conditions
Next the shoot grows up to the light
The first leaves
Embryo becomes primitive root
Lateral roots form
Seeds are dispersed in many different ways:
The carrying of the seed (and its surrounding fruit) as far away from the parent plant as possible
Fruit Wall (Pod)
Pod bursts and flings seeds out
A floating seed is carried by sea or river
A plant produces another plant without involving a second plant
No gamete cells are used.
The plant sends out runners
