Ivy stem, SEM

Ivy stem. Coloured scanning electron micrograph (SEM) of the surface of an ivy plant stem. The star- shaped trichomes, a type of modified hair cell, may function in preventing water loss, or in defending the plant against insects. Several stomata are visible, for example in a line from lower left to centre. These pores allow for gaseous exchange between the air and the plants cells. There are fewer stomata on plant stems than on the leaves

Coloured Sem Gaseous Exchange Hair Cell Horizontal Pore Pores Stem Stoma Stomata Surface Trichome Trichomes Cells

EDITORS COMMENTS
This print showcases the intricate beauty of an ivy plant stem at a microscopic level. The coloured scanning electron micrograph (SEM) reveals a mesmerizing surface adorned with star-shaped trichomes, which are modified hair cells that serve various purposes. These unique structures may play a crucial role in preventing water loss or defending the plant against insects. As we explore this image further, our attention is drawn to several stomata scattered across the stem's surface. Notably, a line of these tiny pores can be observed from the lower left to the center of the photograph. Stomata are vital for gaseous exchange between the air and plant cells, allowing for respiration and photosynthesis to occur efficiently. Interestingly, it becomes apparent that there are fewer stomata on plant stems compared to leaves—a characteristic worth noting. This distinction emphasizes how plants have evolved different strategies for optimizing gas exchange depending on their specific needs. Nature enthusiasts and botany aficionados will find themselves captivated by this horizontal SEM image as it unveils hidden wonders within one of nature's most resilient climbers—the ivy. With its vibrant colors and intricate details captured through advanced microscopy techniques, this print serves as a testament to both scientific curiosity and artistic appreciation for our natural world.
