1. Adaptations for Life on Land:
* Cuticle: A waxy outer layer that prevents water loss.
* Stomata: Tiny pores on leaves that regulate gas exchange (taking in carbon dioxide and releasing oxygen) and control water loss.
* Vascular Tissue: A network of specialized cells (xylem and phloem) that transport water, nutrients, and sugars throughout the plant.
* Roots: Anchoring structures that absorb water and nutrients from the soil.
* Stems: Support structures that elevate leaves and flowers for better access to sunlight and pollinators.
2. Photosynthesis:
* All terrestrial plants have chlorophyll, a green pigment that captures sunlight energy to convert it into chemical energy (sugars) through photosynthesis.
3. Reproduction:
* While reproduction strategies vary among plants, all terrestrial plants reproduce sexually, involving the fusion of male and female gametes.
* Many terrestrial plants also reproduce asexually, creating new individuals from parts of their existing body (e.g., runners, bulbs).
4. Adaptations for Specific Environments:
* Terrestrial plants have evolved a wide range of adaptations to survive in diverse environments, including different climates, soil types, and levels of sunlight. These adaptations can involve leaf shape, root systems, growth patterns, and more.
5. Importance in Ecosystems:
* Terrestrial plants are the foundation of most terrestrial ecosystems. They provide food and shelter for animals, contribute to soil formation, and regulate the global climate.
While these are the main commonalities, keep in mind that the plant kingdom is incredibly diverse. There are many exceptions and variations within these shared characteristics.
