Essential Question: How are plant organs related to their function? Agenda 11/27 Essential Question: How are plant organs related to their function? Complete Plant Reading Road Map Plant Brochure Exit Ticket HW: Finish Plant Brochure We will explain the three tissue systems and the functions of each using a road map. I will label and colored the plant structures. Learning Goal Identify the major plant organs and tissues to function: roots, stems, leaves, flowers, fruits, cones. Diagram and label plant structures.

DERMAL, GROUND, AND VASCULAR TISSUE

DERMAL, GROUND, AND VASCULAR TISSUE

Plant tissues are made of three basic cell types.

Xylem and Phloem

Reading Road Map Xylem: Pg 642 What is the function of xylem and phloem? Xylem: Tissue that carries water and nutrients from the roots to the rest of the plant. Phloem: Tissue that carries the products of photosynthesis (sugar) through the plant

Water and nutrients flow through vascular plant tissues Water and nutrients flow through vascular plant tissues. Tissues are divided into two parts: xylem and phloem. The xylem is located close to the center of the plant; it transports water. A well-known example of xylem is wood, which is how vascular bodies transport water and nutrients to the tops of trees. Also, the xylem consists of dead cells. The phloem, on the other hand, consists of living cells.The phloem is located close to the outside of the plant. The purpose of the phloem is to move organic substances to the upper reaches of the plant.
