Explain what is meant by the terms: Aspect Altitude Why do aloes prefer to grow on North facing slope rather than South facing slope? Give TWO abiotic factors that can be seen in the above diagram Explain TWO structural adaptations of the leaves of aloe plants to its xerophytic mode of life.

In the Southern Hemisphere, North-facing slopes receive more direct sunlight throughout the day compared to South-facing slopes.

This direct sunlight leads to higher temperatures and increased evaporation, resulting in drier soil conditions. Aloes are xerophytic plants, meaning they are adapted to arid environments and thrive in these warmer, drier conditions.

2.1.3 Give TWO abiotic factors that can be seen in the above diagram.

The diagram explicitly shows the sun and different slopes.

• Sunlight (or solar radiation)
• Aspect (or slope/topography)

2.1.4 Explain TWO structural adaptations of the leaves of aloe plants to its xerophytic mode of life.

Aloe leaves are typically thick and fleshy.

• Thick, fleshy leaves: These leaves are succulent and store a large amount of water in their tissues, allowing the plant to survive long periods without rainfall.
• Waxy cuticle: The leaves are covered with a thick, waxy layer (cuticle) that reduces water loss through transpiration by reflecting sunlight and creating a barrier to evaporation.
