Plant Tissues

Dermal, ground, and vascular. Neighboring cells are often connected by

plasmodesmata.

Plasmodesmata are strands of cytoplasm that pass through openings in cell walls and connect living cells.

Label the Plant Tissues

Dermal Tissue Acts similar to human skin. Function:

Covers the outside of a plant, providing protection in a variety of ways.

Made of parenchyma cells

Details: Epidermis is made of live parenchyma cells. Can be made of dead parenchyma cells; makes the

outer bark of woody plants.

Ground Tissue Surrounded by dermal tissue. Function:

Provides support and stores materials in roots and stems.

Made of all three cell types. Parenchyma is most common.

Details: Makes up much of the inside of the plant. Where you can find the chloroplast in leaves.

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

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.
