1984年1月1日 · Scanning electron micrographs of chloroplasts treated with prolonged cytoplasmic maceration show results directly comparable with those obtained in the transmission electron micro- scope. In the parietal cytoplasm around the chloroplasts numerous mitochondria and vacuoles were seen (Fig. 5).

Abstract. Structural changes in chloroplasts of broccoli (Brassica oleracea L., Italica group) florets during senescence were examined using light microscopy, scanning electron microscopy (SEM) with freeze-fracture technique, and transmission electron microscopy (TEM) to better understand the process of chloroplast degradation, particularly at the

Coloured scanning electron micrograph (SEM) of a section through a plant cell, showing a fractured chloroplast (dark green). Chloroplasts are the site of photosynthesis, the process that synthesises carbohydrates from carbon dioxide and water using sunlight.

1977年4月1日 · Scanning electron microscopy has been used to get information about purity and three-dimensional structure of the chloroplast populations that can be isolated by aqueous polymer two-phase partition. The critical point technique was used for drying the chloroplast preparations to avoid destructive surface tension and freeze artifacts.

2018年7月10日 · Here we recapitulate protocols to visualize chloroplasts from Arabidopsis leaves and Phaeodactylum tricornutum cells with confocal and transmission electron microscopy together with a new technique using a focused ion beam-scanning electron microscope (FIB-SEM) allowing for 3D imaging.

Serial block-face scanning electron microscopy (SBFSEM) overcomes the variation introduced by manual sectioning: an internal ultramicrotome cuts 40– 80 nm sections from a resin-embedded sample block, and the newly exposed surface of the sample block is scanned by the SEM.

Here we recapitulate protocols to visualize chloroplasts from Arabidopsis leaves and Phaeodactylum tricornutum cells with confocal and transmission electron microscopy together with a new technique using a focused ion beam-scanning electron microscope (FIB-SEM) allowing for 3D imaging.

1984年1月1日 · Pollen development in Tragopogon porrifolius has been studied in the scanning electron microscope to establish the origin of taxonomically significant features. As in other members of the tribe recently investigated the echinolophate condition is shown to result from differential deposition of the tetrad callose wall and, subsequently, of ...
