Variety of trichomes in Tulsi leaf
Onset of spring season has sprouted new leaves on my tulsi plant. Trichomes were isolated from young tulsi leaves and observed under foldscope. They were of variable shapes and sizes. I wonder if the mature leaves too have similar type and shapes.
Leaf Trichomes of Daucus carota
Certain leaves when eaten cause irritation of throat. Such leaves are not even eaten by cattle and other herbivores. When scratched and seen under foldscope the cause was presence of trichomes on the surface of leaves.
Cells of a dried flower during autumn season seen under foldscsope

White Mold-Sclerotia causing pod rot in peas
Some white, cottony mass was observed on pea pods. The sample observed under foldscope revealed fungal hyphae and black, irregular sclerotia. When these pea pods were split open, white fluffy, slimy mycelium was found inside also. Infection results in production of dense white mycelium which covers the stems, leaves and even the pods. The affected…
