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

Label the Plant Tissues

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

Ground Tissue Surrounded by dermal tissue. Function: Details: 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.

Vascular Tissue Surrounded by ground tissue. Function: Details: 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.

Xylem

Phloem

Plant Growth Plants are able to grow throughout their lifetime due to the presence of undifferentiated tissues called meristems. Meristematic cells are constantly producing new cells these new cells become specialized to form tissues Apical meristems add primary growth and cause the stem to increase in length. Apical meristems are located at the tips of stems and roots. Lateral meristems add secondary growth and cause the plant to increase in girth. Meristems in plants are analogous to stem cells in animals. This tissue is undifferentiated and the cells begin to divide when conditions permit. Explain to students that if you carve your initials in a tree a meter from the ground as a 15 year old teenager, then visit the tree again as a 45 year old adult you’ll find the initials are still only a meter from the ground as a result of apical growth.
