1. Photosynthesis: Land plants are autotrophs, meaning they produce their own food through photosynthesis. They use chlorophyll to capture sunlight and convert it into chemical energy, which is stored in the form of sugars.

2. Multicellular: Land plants are made up of multiple cells, which are organized into tissues and organs. This allows for specialization of function and a greater ability to adapt to their environment.

3. Cuticle: Land plants possess a waxy cuticle on their outer surfaces to prevent water loss. This is crucial for survival in dry terrestrial environments.

4. Alternation of Generations: Land plants have a life cycle that alternates between two distinct multicellular stages: a haploid gametophyte (produces gametes) and a diploid sporophyte (produces spores).

5. Adapted for Terrestrial Life: Land plants have evolved a range of adaptations to survive on land, such as vascular tissue (for transport of water and nutrients), roots (for anchorage and absorption), and stomata (for gas exchange).
