Finding Pollen Grain Images (TEM) for Plant Biology Research

For transmission electron microscopy (TEM) images of pollen grains, these resources are excellent starting points:

• NatureBee.com – shows actual pollen cells.
• Biosicherheit.de/gentransfer/ – includes a TEM image of a pollen zygote with a tube inserted for intracellular extraction.
• HGTV's "The Secret World of Gardens" series – features close-ups of insects transferring pollen; search hgtv.com for episodes.

Additionally, university plant biology departments often host image databases. Search for "pollen TEM" along with specific plant families (e.g., "Poaceae pollen TEM") on academic sites like PubMed Central, ResearchGate, or university herbarium pages.

For your graduate work, consider contacting the palynology lab at your institution or nearby universities—they often have curated TEM libraries.
