flower : : the specialized part of an angiospermous plant that occurs singly or in clusters, possesses whorls of often colorful petals or sepals, and bears the reproductive structures (such as stamens or pistils) involved in the development of seeds and fruit : blossom — Webster
Flower, sometimes known as a bloom or blossom, is the reproductive structure found in plants that are floral (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) or allow selfing (fusion of sperm and egg from the same flower). Some flowers produce diaspores without fertilization (parthenocarpy). Flowers contain sporangia and are the site where gametophytes develop. Many flowers have evolved to be attractive to animals, so as to cause them to be vectors for the transfer of pollen. After fertilization, the ovary of the flower develops into fruit containing seeds. In addition to facilitating the reproduction of flowering plants, flowers have long been admired and used by humans to beautify their environment, and also as objects of romance, ritual, religion, medicine and as a source of food. — Wikipedia

Cells replicate by dividing, but scientists still don't know exactly how they decide when to split. Deciding the right time and the right size to divide is critical for cells – if something goes wrong it can have a big impact, such as with cancer, which is basically a disease of uncontrolled cell division.

Shopping in your supermarket's produce section is like strolling through a museum of humanity's greatest inventions. Perfect ears of golden sweet corn; tomatoes of different sizes, shapes and colors; and spicy jalapeño peppers are all a testament to human ingenuity. You may not consider food an invention, but nearly all foods we eat are the product of thousands of years of constant breeding and selection. […]
More flowers around apple orchards can yield...

Apple growers should increase the amount of flowers around their apple orchards if they want to increase their harvest. A new study by researchers from Stockholm University, among others, shows that more pollinators, such as bees and flower flies, are attracted to orchards with flowers – which increase the chance for pollination.
