“…A similar pollen shape class was observed by Fogle (1977) and Geraci et al (2012). A prolate shape was observed by Chwil (2015) Zuraw et al (2015), who had found that Rosa pollen size ranged from 29.2-34.2 µm in polar and 29.4-33.5 in equatorial view, tricolporate aperture and striate exine. The present study's P/E ratio of 1.09 is similar to the P/E ratio of 1.…”

Pollen grains vary widely in pollen shape, size, aperture type and exine sculpture among the taxa and within the taxon, which make them taxonomically important. They also contain several proteins, lipids and vitamins which are essential for the growth and developments of developing bee larvae. Quantification of these chemical constituents is important for the dietary purposes of honey bees. The present study deals with the morphology and chemical constituents of hand-collected pollen from four bee forage plants viz. Prunus cerasoides D.Don, Prunus persica (L.) Batsch, Pyrus pashia Buch.-Ham. ex D.Don and Rosa brunonii Lindl. from Garhwal Himalaya, Uttarakhand. The family represents a homogenous group with a tricolporate pollen aperture type in all the studied taxa. Pollen shape varied from sub-prolate to prolate-spheroidal with a smaller pollen size observed in Pyrus pashia (26.53±0.30 µm polar view and 24.20±1.04 µm equatorial view) and a larger one in Prunus persica (38.39±3.06 µm polar view and 36.41±1.34 µm equatorial view). Exine sculpture was psilate to striato-reticulate. Maximum crude protein (68.33±0.14 mg/g) and starch content (32.98±0.67 mg/g) were recorded in pollen of Prunus cerasoides and maximum free amino acid (13.78±0.71 mg/g) in Pyrus pashia. All chemical constituents were found to be significant except the amino acids which were non-significant at the 0.05* level. Results showed that pollen grains of these Rosaceous members contained high amount of crude protein and phenolic content as a bee food source for brood, which makes this family economically important.

The signals generated by these stimuli are transferred to the central neural network and brain to provide an appropriate response. In addition, biological skin possesses unique characteristics, such as stretchability, self-healing ability, and mechanical toughness. [1][2][3] It also provides an effective barrier against ambient elements such as chemicals, gases, radiation, and external biological agents.Electronic skin (e-skin) is an artificial smart skin composed of various electronic sensors distributed on a single uniform surface or stacked on multiple surfaces. It mimics some of the biological skin senses and provides a promising sensing platform for key application areas such as wearable sensors, robotics, and prosthetics (Figure 1). [1,[4][5][6][7][8][9][10][11] However, serious concerns have arisen regarding the production of electronic waste (e-waste), the influence of e-skin on human health, the safety of wearable electronic devices, costs, and environmental limitations. These concerns have encouraged researchers to develop biocompatible, renewable, sustainable, and biodegradable flexible wearable detection devices and biosensing platforms. [12][13][14][15][16] Biological skin regularly regenerates the old superficial layer of the epidermis with new skin cells during the healing process. Inspired by this natural degradation cycle, artificial biodegradable skin-based electronics should be designed for programmable degradation, in contrast to conventional electronic materials. To achieve this goal, the development of biocompatible, environmentally friendly electronic systems that can be used for the fabrication of biodegradable and sustainable e-skins is important.Various low-cost, nontoxic, renewable, and natural substances and polymer-based materials that can be applied to the development of sustainable, biodegradable e-skins and alleviate the environmental and health risks of e-waste materials are available. [17][18][19][20][21][22] E-waste disrupts the biological activity of microbial enzymes and their metabolisms, which decreases the resistance and the diversity of soil-based microbial communities. [23] In addition, in the human body, the accumulation of metals and metalloids used in the fabrication of conventional electronics can cause a range of biophysical malfunctions and diseases, such as liver damage by Cu, behavioral disorders by Pb, and lung cancer and kidney damage by Cd. [24][25][26][27] The rapid growth of the electronics industry and proliferation of electronic materials and telecommunications technologies has led to the release of a massive amount of untreated electronic waste (e-waste) into the environment. Consequently, catastrophic environmental damage at the microbiome level and serious human health diseases threaten the natural fate of the planet. Currently, the demand for wearable electronics for applications in personalized medicine, electronic skins (e-skins), and health monitoring is substantial and growing. Therefore, "green" characteristics such as biodegradability, self-healin...
