This fungus consists of single vegetative cells. Small daughter cells can be seen budding off from the larger cell. S. cerevisiae ferments sugar, producing alcohol and carbon dioxide in the process.

Lung alveoli, SEM Credit: EYE OF SCIENCE/SCIENCE PHOTO LIBRARY Alveoli in a human lung. Each alveolus is a site for gas exchange between the air in the air sac and the blood in adjacent capillaries. Red blood cells (erythrocytes) can be seen through the walls of the alveoli.

Writing Dry Ice! I am confusingly cold. As white as muddy snow, rolling Diamonds glinting in the sun. I bash, dent and chip. Sticky substance to touch, it burns, it hurts, It curls and swirls. Floating boxes, drifting along, Thousands of doors to open with a creak. I crackle like falling caves. When I open my steamy souls. Dark and dangerous I can be. Crosses you notice all over me. My end is near, heat I fear! DRY ICE! I shout By Minnie M It oozes and sucks, The mud glints in the sun, Poisoned, polluted, Sucking down its helpless, struggling victims. Swirling treacherous waters, Like portals to other worlds, Thick black mud holds people down, As the deadly waters choke them to death. The bubbles floating on their voyage, Through scummy waters, Are like frogspawn That will never hatch. But then the sun comes out, The marsh is defeated, It retreats, And sinks back into the soil.
