Description

Leaf pores. Coloured scanning electron micrograph (SEM) of stomata (holes) on the surface of a leaf. These structures perform a similar function to the pores in human skin, allowing water to pass out of the leaf. They also act like lungs, allowing carbon dioxide and oxygen (found in air) to pass into and out of the leaf. The stomata can be opened and closed depending on the conditions and the need to retain water. Water and carbon dioxide are combined in photosynthesis to produce sugars (transported around the plant in veins, one seen, brown) and oxygen (released via the stoma). This is a coriander plant leaf (Coriandrum sativum).

    Clear advanced search
    to get more results.
    Try again with these tips.
    • Check your search term for any typos.
    • Try other spellings, like “theatre” instead “theater”, or “colour” instead of “color”.
    • Find synonyms, like “butter” instead of “margarine”, or “pop” vs. “soda”.
    • Try “general” versions of your search, like “alien” instead of “martian” or “burger” instead of “big mac”.
    • For long queries, like “cat jumping out of a yellow brick window”, try deleting some words, in this case you would try “cat jumping yellow window”. This is merely an example.
    • Make a request in our forums, or contact us with any issues.
