Hyphae and asci of Sphaerotheca mildew Featured 7 Apr 2004 Image

Hyphae and asci of Sphaerotheca mildew

Mildew. Coloured Scanning Electron Micrograph of hyphae and ripe asci of the leaf mildew Sphaerotheca sp. The hyphae are the tangled filaments which make up a fungal colony. Asci (singular ascus) are the aerial, club-shaped spore-forming bodies seen here. Inside an ascus, eight ascospores develop and are violently discharged when ripe. The ascospores are carried away by air currents and may produce a new fungal colony if they land on appropriate material. Sphaerotheca species are plant parasites, various species invading the leaves and buds of dandelions, hops, gooseberries and roses. Magnification: x300 at 5x7cm size. x1950 at 10x8ins

False-colour SEM of connective tissue Featured 7 Apr 2004 Image

False-colour SEM of connective tissue

False-colour scanning electron micrograph (SEM) of human connective tissue, showing collagen fibres, which appear as an irregular mass of yellow strands. Red blood cells (erythrocytes) are interspersed between the fibres. Connective tissue provides metabolic and structural support for other tissues and organs throughout the body; more distinct & specialised systems include bone, blood, tendons & ligaments. Fibres comprising connective tissue are of 3 types: collagen, reticular & elastic. Where properties of strength & elasticity are required (as with tendons & ligaments), the fibres are densely & regularly packed. Magnification: X 440 at 35mm size
