WHITE FLOWER

Nano Flowers

Beauty is in the eye of the beholder and nanotechnology can sure look spectacular! Ghim Wei Ho, is a Ph.D. student working for Professor Mark Welland, at the University of Cambridge Nanoscale Science Laboratory and has produced some spectacular images of nano-flowers. They are three-dimensional Si composite nanostructures, taken with a scanning electron microscope. Ghim Wei Ho’s Ph.D. project in the Nanoscience Centre involves the fabrication and characterisation of novel nanostructures. In addition to ‘flowers’ Ghim Wei Ho can also grow nanowires, cones, rings etc.

Welcome to Botany.com's botanical dictionary of plants and flowers. A botanical dictionary is also commonly referred to as a plant dictionary or flower dictionary. Use this outdoor and indoor plant resource to look up words used to describe plants, flower parts, types of foliage, plant living processes and growing habits, as well as leaf shapes, and much more.

Cactus

n cacti the ovary is inferior, that is the flower is located above the ovary, sometimes with an elongated tube. The flower is usually regular or symmetrical, that is it forms equal halves whichever plane it is sliced across. Some are asymmetrical or zygomorphic, that is it only has one plane of symmetry eg Cleistocactus, Borzicactus and Schlumbergera.

Anatomy of a flower

Angiosperms or flowering plants produce flowers soley for the reproduction of the plant. Like animals there are female and male reproductive organs.
Flowers are extremely diverse in size, shape, color, and many other factors. This means they are excellent for identifying plants and their relationship to other plants, especially as the flower does not change according to environmental conditions, unlike say shape of plant, leaves and stems.
