In which of the following structures would you be surprised to find stomata?
Answer:
Stomata are tiny openings or pores found in the epidermis of leaves and stems, which are essential for gas exchange in plants. Typically, stomata are mainly found on the underside of leaves, but there are some structures where you would be surprised to find stomata due to their unusual or unexpected locations:
-
Roots: While stomata are not typically found on roots, certain aquatic plants, like water lilies, may have stomata on their roots to facilitate gas exchange in submerged conditions. This adaptation allows these plants to absorb oxygen and release carbon dioxide even from their roots.
-
Flowers: Stomata are not commonly found on flowers, which are reproductive structures of plants. However, some succulent plants such as cacti have stomata on their flower petals to aid in transpiration and gas exchange.
-
Fruits: Stomata are usually absent on fruits since their primary function is to protect and contain seeds. However, some fruits like apples may have remnants of stomata on their surface from when they were developing as flowers.
-
Petioles and Stems: Stems are not the most common location for stomata, but certain plants may have stomata on their stems and petioles. This unique arrangement allows these plants to regulate transpiration and gas exchange through additional surfaces.
In conclusion, while stomata are typically found on the underside of leaves, there are some exceptional cases where stomata can be present in surprising structures like roots, flowers, fruits, and stems for specialized functions in certain plant species.
