•    Some facts about flowers are that flowers get their food from sunlight, water, and minerals in the soil; flowers are the reproductive parts of a plant, and plants make their own food by photosynthesis.

•    Plants can photosynthesize due to cells called chloroplasts that contain chlorophyll; this is what makes plants green. Sun strikes the chloroplasts and combines with carbon dioxide that plants get from their leaves, and water that plants get through their roots, to produce sugar, or glucose. This is the plant's food, and this gives the plant energy to grow and produce flowers.

•    Sometimes people add fertilizer, or plant food, to give plants extra minerals and nutrients so that they can grow better. Fertilizer does not take the place of sunlight and water. Without sunlight and water, plants will die.

•    Inside a flower is the pistil, or the female parts of the flower. The pistil looks like a vase with a long neck. The top of this ‘vase’ is called the stigma. The long neck is called the style. The bottom, fatter part of the vase is the ovary and contains the ovules, or eggs.

•    Flowers did not always exist; they first appeared 140 million years ago. Before that, ferns and cone bearing trees dominated the earth.

•    Several centuries ago in Holland, tulips were more valuable than gold.

•    Some plants such as orchids do not need soil to grow - they get all of their nutrients from the air.

     •    Some plants produce toxic substances that kill other plants around them - the sunflower is an example.
