1. Structural Support and Height: Trees, with their complex tissues and specialized cells, can grow tall and sturdy. This allows them to access sunlight more effectively, competing with other plants for resources. Single-celled algae, on the other hand, are limited in size and can only thrive in environments where they can access sufficient light.
2. Specialized Tissues and Organs: Multi-celled organisms like trees have specialized cells that form tissues and organs. This allows them to perform complex functions like transporting water and nutrients, producing food through photosynthesis, and reproducing efficiently. Algae lack this level of complexity, which limits their overall capabilities.
