Explanation:

Geranium leaves are typically arranged in a way that allows for optimal use of light through a process called "heliotropism" or "solar tracking."

Heliotropism is the ability of plants to orient themselves towards the direction of the sun to optimize their exposure to light.

Geranium leaves are arranged in a rosette pattern, with each leaf emerging from the base of the stem and spreading outwards. The leaves are arranged in a way that maximizes their surface area while minimizing shading of other leaves. This arrangement allows the leaves to capture the maximum amount of sunlight possible.

Additionally, geranium leaves have a waxy cuticle that helps to prevent excessive water loss and damage from UV radiation. The leaves also have chloroplasts, which contain chlorophyll and are responsible for photosynthesis, the process by which plants use sunlight to produce energy.
