Wheat grain, light micrograph
Wheat grain. Light micrograph of a vertical section through a grain of wheat (Triticum vulgare). This is the fruit of the plant, and includes the endosperm (larger area, pink), which is full of food in the form of starch grains and protein crystals. The seed (smaller area at upper right, blue) contains the embryo. The embryonic area includes a plumule and radicle enclosed within the coleoptile and coleorhiza respectively. The plumule and radicle are the structures by which the seed will germinate and develop a root and leaf system, developing into a new plant. The endosperm provides nutrients for the germinating plant. Wheat is a crop that is cultivated for its grains, which are a rich source of starch

EDITORS COMMENTS
This print showcases the intricate beauty of a wheat grain at a microscopic level. The light micrograph reveals a vertical section through the grain, providing us with an intimate glimpse into its anatomy and reproductive process. At first glance, we are drawn to the larger area colored in pink, which represents the endosperm - a vital part of the fruit that stores food in the form of starch grains and protein crystals. Intriguingly, within this larger area lies a smaller blue section known as the seed. This tiny compartment houses the embryo, consisting of both plumule and radicle enclosed within protective structures called coleoptile and coleorhiza respectively. These embryonic components play crucial roles in germination by developing roots and leaves that will eventually grow into a new plant. The nutritious endosperm acts as fuel for this germinating plant, ensuring its successful growth and development. Wheat is widely cultivated for its abundant grains, renowned for their high starch content. As one of nature's bountiful sources of carbohydrates, these grains serve as an essential staple in our diets. This extraordinary image not only highlights the fascinating intricacies of wheat reproduction but also emphasizes its significance in agriculture and food production worldwide. Through meticulous microscopy techniques employed by Science Photo Library's experts, we are granted access to an awe-inspiring world hidden from plain sight – where science meets artistry to capture nature's wonders on film.
