  1. What are tissues made of? Tissues are a group of cells working together to perform a certain function. . Plant Tissues • There are 3 tissue systems in plants: • Dermal tissue • Ground tissue • Vascular tissue

  2. Plant Tissues • Neighboring cells are often connected by plasmodesmata. • Plasmodesmata are strands of cytoplasm that pass through openings in cell walls and connect living cells.

  3. Label the Plant Tissues

  4. Dermal Tissue • Acts similar to human skin. • Function: • Covers the outside of a plant, providing protection in a variety of ways. Details: • Epidermis is made of live parenchyma cells. • Can be made of dead parenchyma cells; makes the outer bark of woody plants. • Cell types: Made of parenchyma cells

  5. Ground Tissue • Surrounded by dermal tissue. • Function: • Provides support and stores materials in roots and stems. • Details: • Makes up much of the inside of the plant. • Where you can find the chloroplasts in leaves. • Made of all three cell types. Parenchyma is most common.

  6. Vascular Tissue • Surrounded by ground tissue. • Function: • Transports water, mineral nutrients, and organic compounds to all parts of the plant. • Details: • Made of two networks of hollow tubes. • Xylem and Phloem

  7. Cell types in Phloem – Sieve tube elements, companion cells Cell types in Xylem – Tracheid cells and vessel elements

  8. Xylem and Phloem • Similar to our veins and arteries. • Xylem: carries water and dissolved mineral nutrients up from roots to the rest of the plant. • Phloem: the vascular tissue that carries the products of photosynthesis through the plant.
