Spore bags of helminthosporium contain 8 cells. This disease causes helminthosporiosis of wheat. Soon very small and quite harmful.

Squash preparation of stained onion root tip cells showing late telophase and metaphase stages of mitosis. Bright field illumination on a Leica microscope, Image taken with the X100 objective lens. Depth of focus is extremely shallow (less than one micron). Optimum setting of the aperture for maximum resolution and good contrast. Chromatic aberation is inevitable in light microscopy, especially at this scale of magnification, but has been kept to a minimum in this image.

Epidermis. Electron microscope micrograph showing a keratinocyte of spinous layer. The epithelial cell has a polygonal shape, central nucleus with nucleolus, cytoplasm full of keratin filament bundles, and numerous dark desmosomes crossing the intercellular spaces.

$Sedum kamtschaticum, commonly known as Kamchatka sedum or Kamchatka stonecrop, is a compact low-growing ground cover that forms a foliage mat of 15cm tall with spread of trailing stems to 30-45” wide. It is native to northern China and along the Pacific coast of Siberia including Kamchatka Peninsula.\nThick, triangular, succulent, spatulate to obovate, semi-evergreen, dark green leaves are deciduous at the stem bases but tend to be evergreen at the tips. Tiny, star-shaped, yellow flowers bloom in flat cymes in June-August. Flowers give way to small fruits which turn red in fall.$
