Nature Prefers Asymmetrical Pollen Grains, Study Finds News
Here, we describe methods of transmission electron microscopy (TEM) based on conventional chemical fixation and high-pressure freezing (HPF) and freeze-substitution (FS) to examine the ultrastructure of Arabidopsis pollen grains and pollen tubes.

SMOOTH OVER Pollen grains from flowering plants can be relatively smooth (one shown in this scanning electron microscope image at left). Computer simulations of pollen formation show that halting.
GMS Scanning Electron Microscope Still Image of Pollen Particles
This study employs scanning electron microscopy (SEM) to delve into the intricate pollen morphology of Cucurbitaceae (Gourd Family) species, unraveling the nuanced details of their structural features. Concurrently, the research investigates the antimicrobial potentials encoded within these pollen.

soil analysis. Palynologists rely on light microscopy (LM) to identify and interpret the pollen spectrum of a particular sample. Scanning electron microscopy (SEM) is not normally used for counting and identifying pollen grains. Instead, SEM is mainly used for morphological comparisons and taxonomy where the increased resolution of SEM makes.

The electron-micrographs were made using a Quanta 250 microscope (FEI Company) and JEOL 6390LV microscope. Descriptions follow Punt et al. (2007) , and the produced slides were deposited at the pollen library of Plant Micromorphology Laboratory (LAMIV), of the State University of Feira de Santana.

Hitherto such studies have used optical or transmission electron microscopy but here a recently devised preparative technique has enabled pollen development in Cosmos bipinnatus to be studied using the scanning electron microscope. The technique involves freeze-fracturing of osmium fixed, cryoprotected anthers, maceration in dilute osmium.

A scanning electrode microscope ( SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition of the sample.
