    Title : Germinating seed, SEM
    File Name : 132_1200514-W.jpg
    ID Number : 132_1200514
    Caption : Germinating seed. Coloured scanning electron micrograph (SEM) of the main stages in the germination of a plant seed. The sequence runs from left to right. The first two images show the emergence of the radicle (white), the embryonic root, from the seed coat (testa, brown). In the third image, the root grows downwards in response to gravity (geotropism), while in the fourth image the embryonic shoot (plumule) grows up against gravity. Its seed leaves (cotyledons, green) will photosynthesise using sunlight. The root 'hairs' will help obtain water and nutrients. This is a swede (Brassica napus) seedling. Credit    : POWER AND SYRED / SCIENCE PHOTO LIBRARY / Universal Images Group

    Title : Germinating coconut palm
    File Name : 132_1204501-W.jpg
    ID Number : 132_1204501
    Caption : Germinating coconut palm (Cocos nucifera) on a beach in Barbados. A coconut palm can grow up to 30 metres high and will begin to bear fruit (coconuts) roughly 7 years after germination. Coconuts take between 8 to 10 months to fully ripen. Young, green coconuts contain a nutritious liquid, rich in vitamin C, and a soft, jelly-like flesh, while ripened fruit conatin a thicker liquid (milk) and white, solid flesh that is used in cooking rather than eaten raw.

    Title : Garlic clove germination experiment
    File Name : 132_1210039-W.jpg
    ID Number : 132_1210039
    Caption : Garlic clove germination experiment. Image 2 of 3. The clove of garlic (Allium sativum) has been impaled on a pin and suspended with its root tip in a test tube of water. Left exposed to air and light, and at a suitable range of temperatures, the clove (which is the seed of the plant) has germinated and started to grow roots (white). The next stage in the growth of a new garlic plant will be the emergence of leaf shoot from the other end of the clove. The stages of the germination and growth process can be seen in images B787/634 to B787/636.
