GCSE Biology - Structure of a Leaf and Stomata #50

The video explores plant structure, focusing on how cells form tissues, organs, and organ systems. It examines the leaf's structure, highlighting its role in photosynthesis, which requires carbon dioxide and water. The process of photosynthesis is detailed, including the transport of sugars via the Floum. The video also addresses water loss issues in leaves and the function of stomata and guard cells in regulating gas exchange and water conservation. Lastly, it discusses meristem tissue's role in plant growth and differentiation.

Explain the role of stomata in gas exchange.

What is the significance of the palisade mesophyll layer in leaves?
