For sexual reproduction to take place pollen from the anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety of one flower must land on the anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety of another flower. This is called anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety. Pollen grains can be carried by insects like bees and these tend to be anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety so that they can stick onto the body of insects.

Pollen grains carried by the wind are anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety and light.

When pollen lands onto a stigma it grows a anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety inside the style. It grows anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety towards the anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety. The growth of the pollen tube can be controlled by anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety solution. The anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety of the pollen travel down this tube.

When the pollen tube reaches the ovule the nucleus of the pollen grain will anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety with the nucleus of the egg cell. This is called anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety. A fertilised egg cell is formed. The new nucleus inside this fertilised egg cell will now have all the necessary anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety to make a new cell.

anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety of this information comes from one plant and the anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety from the other plant. Because the new plant has some features from both parent plants it is said to be a new anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety.

The fertilised egg will grow and divide. Eventually it will become an anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety.
The ovule will become the anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety and the ovary will become the anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety which swells up. The fleshy part of an apple is what we eat and the core of the apple is where we find the seeds that once was the ovule.

There are two main types of pollination

When pollen grain from a flower of a plant gets to the stigma of a flower on the same plant we call this anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety.

When pollen grain from a flower of a plant gets to the stigma of a flower on another plant we call this anthercross pollinationdownwardsembryofertilisationfruitHalfinformationjoinnucleusother halfovarypollen tubepollinationseedself pollinationsmallspikeystigmasugarvariety. Cross pollination allows new varieties to be formed.
