Plant Tissues, Structure and Function

Plants have 4 different types of tissues that help them survive. Plant Tissues Plants have 4 different types of tissues that help them survive. Dermal Tissue Ground Tissue Meristematic Tissue Vascular Tissue

Tissue that covers the plant. Dermal Tissue Tissue that covers the plant. Epidermis Periderm - Cork/Bark On non woody parts On woody parts of the plant Made of dead cells

Ground Tissue Tissue that makes up the inside of plants. It is specialized to: Carry out photosynthesis in the leaves Store photosynthetic products Glucose Support the plant

There are 2 types of vascular tissue: Moves water, dissolved minerals and nutrients throughout the plant body. There are 2 types of vascular tissue: Xylem Moves Water Phloem Moves Nutrients

Moves sugar and minerals down. Vascular Tissue Xylem Phloem Moves water up Moves sugar and minerals down.

Tubes that allow sugar and minerals to move down through the plant. Vascular Tissue Xylem Phloem Hollow, water-proof tubes that allow water to rise up in the plant via capillary action Tubes that allow sugar and minerals to move down through the plant.

Xylem Phloem

Plants have 2 types of meristematic tissue Mertistematic Tissue Tissue that allows the plant to grow up, down and/or out. Where mitosis occurs! Plants have 2 types of meristematic tissue Apical Meristem Allows growth at the tips of roots and branches….up and down Vascular Cambium In the outer layer of the stem/trunk that allows outward growth (thickness)

Bundles in a non-woody plant Mertistematic Tissue Apical Meristem Vascular Cambium Bundles in a non-woody plant Root tip

Plants have 3 main structures Structures Overview Plants have 3 main structures Roots A system for absorbing dissolved minerals and nutrients as well as water Stems A structure used to support the body of the plant Leaves The main photosynthetic regions of the plant.

Roots Help to anchor the plant to the ground Absorb water and dissolved nutrients/minerals Root hairs increase the surface area to increase absorption Storage Sugars such as starch Propagation
