External leaves, such as the oak or maple leaves, are typically broad and flat, designed to capture sunlight for photosynthesis and often exhibit vibrant colors in the fall. Internal leaves, like those found in certain plants such as the aloe vera or some types of succulents, are modified to store water and nutrients, often appearing fleshy or thickened. Both types serve crucial functions in their respective environments, adapting to different conditions and needs.
Leaf is an external organ of the plant
no one
at the external layer is the lamina which is the flat leaf. there is also the network of veins which provides the minerals.furthermore is the petiole which holds the leaf the the main branch.lastly is the cuticle which prevents excessive loss of water of the plant. this is the internal structure of the leaf courtesy from www.wikipedia.org HI
draw internal leaf
The external leaf structure serves to protect the internal tissues of the leaf, regulate gas exchange through tiny openings called stomata, and capture sunlight for photosynthesis through chlorophyll-containing cells.
the internal make up of a leaf isn't really complex the chloroplast is the main component in photosynthesis because it captures sunlight.
The external structures/parts of the flower are: 1. Dermal tissue 2. Cuticle 3. Ground tissue 4. Air spaces 5. Guard cell 6. Stomata
In "The Last Leaf", the first conflict is whether the last leaf will drop or not. To be more clear, whether Johnsy will die or not. The second one is whether Behrman will paint a masterpiece or not.

The exchange of oxygen and carbon dioxide between internal leaf cells and the external environment is crucial for photosynthesis and respiration. During photosynthesis, cells take in carbon dioxide and release oxygen, while during respiration, cells take in oxygen and release carbon dioxide. This exchange allows plants to produce energy and oxygen while removing carbon dioxide from the air.
