How leaves pull water upward
See how transpiration, stomata, cohesion, and xylem connect evaporation at a leaf to water movement through a plant.
Nature science
Use visible details as evidence while keeping uncertainty clear when a species, microscopic process, or environmental cause cannot be confirmed from one photo.
Families, walkers, gardeners, and learners observing nature without disturbing it.

Biology
See how transpiration, stomata, cohesion, and xylem connect evaporation at a leaf to water movement through a plant.
Include the whole leaf, habitat, sky, or surrounding material as well as the detail that caught your eye.
Check whether lighting, moisture, damage, or a similar-looking species could explain the image.
Observe in place whenever possible and avoid handling unknown plants, fungi, or animals.
Do not use image analysis to decide whether a plant, mushroom, animal, or substance is safe to touch or eat.
Choose a depth before analysis and keep the result private unless you decide to share it.
