Cactus seed, SEM
Cactus seed. Coloured scanning electron micrograph (SEM) of a seed from a cactus flower (family Cactaceae). A seed contains an embryo (a fertilised ovule from which a new plant can grow), and a supply of food. The food is used either while the embryo grows within the developing seed, or during germination. Seed shapes and surface textures vary widely, affecting how they are dispersed from their parent plant. Seed dispersal methods include being carried by the wind, or water or on animal coats, or being eaten and deposited in animal droppings. Cactus seeds are usually dispersed in animal droppings. The cacti are succulent plants adapted to grow in arid areas like deserts. Magnification: x830 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of a cactus seed, captured through a coloured scanning electron micrograph (SEM). The seed, belonging to the Cactaceae family, holds within it the potential for new life - an embryo ready to sprout into a thriving plant. Alongside this precious embryo is a vital supply of food that sustains its growth and nourishment. The diverse shapes and textures of seeds greatly influence how they are dispersed from their parent plants. In the case of cacti, these resilient succulent plants have adapted to arid environments like deserts. To ensure their survival in such harsh conditions, cactus seeds rely on animal droppings as their primary means of dispersal. Nature's ingenious ways never cease to amaze us; whether carried by wind or water or clinging onto animal coats, seeds find unique methods to reach new territories where they can take root and flourish. This SEM image reveals the hidden wonders within a single cactus seed - an extraordinary example of nature's reproductive prowess. With magnification at x830 when printed 10 centimetres wide, this photograph allows us to appreciate the intricate structures and details that make up this tiny but essential part of plant life. It serves as a reminder that even in seemingly barren landscapes like deserts, life finds remarkable ways to persist and thrive against all odds.
