Why was it important in today’s exercise to sever the stems while they were submerged in water?

Question

Accepted Answer

∻Answer∻ ⚹ Severing the stems while they were submerged in water is crucial to prevent air embolisms in the xylem vessels, which can block water uptake. ⚹ ∻Solution∻ ‖ a ⋮ Prevention of Air Embolism: When stems are cut in the air, air bubbles can enter the xylem vessels, creating air embolisms that block the flow of water and nutrients. Cutting the stems underwater prevents this by ensuring that water, not air, fills the xylem vessels. ‖ ‖ b ⋮ Continuous Water Column: Maintaining a continuous column of water in the xylem is essential for the plant's ability to transport water from the roots to the leaves through capillary action and transpiration pull. ‖ ∻Key Concept∻ ⚹ Air Embolism Prevention ⚹ ∻Explanation∻ ⚹ Cutting stems underwater prevents air bubbles from entering the xylem, ensuring efficient water transport within the plant. ⚹◊What biological process occurs in plants when stems are severed while submerged in water?⍭ Generate me a similar question◊
