Although all parts of a plant are important, the bud has a very essential purpose. Its job it to attract butterflies and bees to that plant which is beneficial to both the insects and the plants.
The insects collect pollen from the pollen sacks contained in the bud, which the bees can take back to their hive. But during the fertilization season, pollen grains can get stuck to the insects, who then travel to other flowers and then start the whole fertilization process. Below is an explanation of how this process occurs:
• The fertilization process in plants occurs when pollen grains (considered to be male gametophytes) are carried to a female gametophyte on another plant (the open ovule which contains the eggs to be fertilized). Plants are asexual which means that the offspring can be formed by one parent.
• Pollen can be carried by the wind or by being stuck to insects and released on another flower.
• Once the pollen has been dropped in the ovule, it will develop into an outgrowth called a pollen tube. Here it will eventually penetrate the egg cell which is contained in one of the archegonia.
• The sperm cells will then fertilize the egg.
• Once this fertilization has taken place, an embryo will develop inside the female gametophyte. The ovule proceeds to become the new seed but also has the gametophyte tissue which a food source and the integument which is a seed coat.
• Once the embryo has finished developing, it will become a new sporophyte. This consists of the hypocotyl and the epicotyl which are two embryonic leaves.
