Question

Why do gases came out of the leaf when it was put into warm water

Answer 1

Answer:

The leaf is using light to maintain photosynthesis when it is underwater. Oxygenating the leaves is a step in this process. You are observing bubbles in the water, which are caused by this oxygen. So even though plants don't use lungs to breathe like humans do, they nonetheless take in and expel air.

Explanation:

• The needs for gas exchange are taken care of by each component of the plant. Although plants have sophisticated liquid transport systems, they are not involved in the transfer of gases.
• Respiration rates in roots, stems, and leaves are substantially lower than those found in animals. Large amounts of gases are only transferred during photosynthesis, and each leaf is well-adapted to meet its individual needs.
• Even in a large plant, the distance over which gases must disperse is not very significant. The plant's live cells are all found close to the surface. It is clear for leaves, but it also holds true for stems. Only living cells can be found in the stem, and they are arranged in thin layers immediately below the bark. The interior's dead cells solely serve to support the body's mechanics.
• In a plant, the majority of the live cells have at least a portion of their surface exposed to the air. A network of air voids is created by the loose arrangement of parenchyma cells in leaves, stems, and roots. Gases disperse through the air thousands of times more quickly than they do through water. Once in the network of intercellular air gaps (arrows), oxygen and carbon dioxide diffuse quickly across them.
• By diffusion, oxygen and carbon dioxide also pass through the cell's plasma membrane and cell wall. Aquaporin channels that have been introduced into the plasma membrane may aid in the diffusion of carbon dioxide.
