1. Ground Tissue: This is the most abundant tissue type and makes up the bulk of the plant. It's responsible for:
* Photosynthesis: In leaves, ground tissue contains chloroplasts and performs photosynthesis.
* Storage: Ground tissue in roots, stems, and fruits stores water, nutrients, and starches.
* Support: Some ground tissue provides structural support for the plant.
2. Vascular Tissue: This tissue is responsible for transporting water and nutrients throughout the plant. There are two main types:
* Xylem: Transports water and minerals upwards from the roots to the rest of the plant.
* Phloem: Transports sugars (produced during photosynthesis) from the leaves to other parts of the plant for growth and storage.
3. Dermal Tissue: This tissue forms the outer protective layer of the plant. It includes:
* Epidermis: The outermost layer of cells, covering leaves, stems, and roots. It helps prevent water loss and regulates gas exchange.
* Periderm: A tougher, protective layer that replaces the epidermis in older stems and roots.
These are just the main tissue types. Within each type, there are various specialized cells and tissues that contribute to the overall structure and function of the plant.
