Acacia Pollen in REM Pollen grains contain male gametophytes which are ultimately meant to alight upon the proper carpel to unite with the female gametophyte cell and ultimately germinate into a genetically different offspring (my apologies to any impressionable readers out there).  Spring is such a difficult time for allergy sufferers because many common trees and grasses utilize this time of year for pollination: flowers are unblocked by mature leaves and a whole growing season stretches…

Resin cast of arteries in the brain. Your brain consumes about 20% of your body's energy so it needs a lot of blood flow to keep it supplied with nutrients. Even knowing that, the density of the neurons here amazes me--they look almost the size of the brain itself!

The cancer cell's pink mitochondria and gold endoplasmic reticulum--a network of vesicles and sacs--swirl around a dark nucleus. The rendering was awarded an honorable mention in the illustration category of the 2008 International Science and Engineering Visualization Challenge.     Donald Bliss and Sriram Subramaniam of the National Institutes of Health's National Library of Medicine created the image by "sandblasting" the cell with ions of the element gallium.

El ovulo, es la célula o gameto sexual femenino, es de forma esférica, contiene gran cantidad de citoplasma y un núcleo con 23 cromosomas. Un ovulo humano mide en promedio 1.5 mm, el cual puede verse con facilidad. De hecho, es la célula más grande del cuerpo. El espermatozoide es la célula o gameto sexual masculino, de él se distinguen la cabeza, el cuello y flagelo. Un espermatozoide mide 5 ó 6 micras de largo y 2 ó 3 de ancho (una micra es la milésima parte de un milímetro)
