Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.

Achillea millefolium, commonly known as White Yarrow or Common Yarrow, is a graceful perennial flower that produces an abundance of huge, flat clusters, packed with creamy-white flowers. They are born on tall stems atop an aromatic, green, fern-like foliage. Both flowers and foliage are attractive and long lasting, making White Yarrow a wonderful garden plant and a great choice for prairie or meadow plantings.\nIt is a rhizomatous, spreading, upright to mat-forming. Cultivars extend the range of flower colors to include pink, red, cream, yellow and bicolor pastels.

Photomicrograph of rotifer, probably Rotaria rotatoria. Rapidly rotating cilia at top of head, internal organs visible. Green circles are algae. Live specimen. Original image at 40X, wet mount, transmitted brightfield illumination. Indistinct image due to motion blur of live specimen and very shallow depth of field of brightfield illumination.

Low biennial or perennial, sometimes annual, with a solitary or several rosettes. Leaves linear to lanceolate, often pinnately-lobed, toothed, hairless or finely hairy. Flowers yellowish-brown, 3mm, in long spikes on enridged stalks longer than the leaves; anthers pale yellow.\nHabitat: Coastal places, sandy or gravelly soils, occasionally inland.\nFlower Season: May-July.\nDistribution: Throughout, except the far North.
Representatives of the Lemnaceae, the duckweed family, are well-adapted for use as bioindicators for testing soil and water for toxic substances. Their rapid multiplication and the simplicity of their anatomy are important advantages for this use.
