WARNING: The bitmap (BMP) images are over 1 megabyte per image! Full-sized
jpegs are usually only about 40 kilobytes. We recommend downloading jpegs

SCALE: Unless otherwise noted, these images are two centimeters wide and just under
one and a half centimeters tall. To estimate the dimensions of zoom images, compare
to their corresponding wide-angle shot. A fully-zoomed image can represent an area
of the soil a mere three millimeters wide and two millimeters tall!

|
Site (plant species): Genist monspessulana Could be more root hairs, but the assymetry suggests that some of those wispy threads may be fungal. |

Site (plant species): Genist monspessulana Nice example of hairy roots... |
|
|
Site (plant species): Genist monspessulana Dramatic zoom shot of a dense zone of root hairs. Notice that the densely hairy areas are growing preferentially in certain areas. Perhaps the plant is exploiting localized zones of high nutrient availability. |
|
|
Site (plant species): Genist monspessulana Here again we see dense root hairs growing in specific zones on the root surface. |
